Food adulteration is a global issue, and because there are insufficient regulations and oversight, developing nations are more vulnerable to it. But in many nations, food adulteration has gone unnoticed. Contrary to popular assumption, milk adulterants can, regrettably, present major health risks that result in fatal diseases. Modern milk adulteration involves increasingly complex techniques, necessitating state- of- the- art research to identify the adulterants. Because milk contains so many nutrients that are needed by both adults and infants, it is referred to as the ideal food. In terms of protein, fat, carbohydrates, vitamins, and minerals, it is among the best sources. Regretfully, milk adulteration is a very common problem worldwide. Potential causes could be the gap between supply and demand, the perishable nature of milk, the low purchasing power of the consumer, and the absence of appropriate detection tests. Because there is insufficient oversight and inadequate law enforcement, the situation is substantially worse in developing and underdeveloped nations. While quantitative detections of adulterants in milk are varied and complex, qualitative detections can be carried out simply using chemical reactions. The type of quantitative detection methods used depends on the milk’s adulterants.

Typical Adulterants in Milk

The addition of vegetable protein, milk from different species, whey addition, and watering are the main adulterants in milk that are known to be economically motivated. There is no serious health risk associated with these adulterations. Some adulterants, though, are too dangerous to ignore. Urea, formalin, detergents, ammonium sulfate, boric acid, caustic soda, benzoic acid, salicylic acid, hydrogen peroxide, sugars, and melamine are a few of the main adulterants in milk that have been shown to have serious negative health effects.

The terms “cultured dairy foods,” “cultured dairy products,” and “cultured milk products” are other terms for fermented dairy products. Lactobacillus, Lactococcus, Leuconostoc, and other lactic acid bacteria, along with yeasts in certain products, are used to ferment milk to make these dairy products. The product’s shelf life is extended through fermentation, which also improves the product’s taste and milk’s digestibility. There is a wide variety of fermented milk products available, each with unique flavors and attributes. The following categories apply to fermented milk products, based on the type of fermentation.

Changes in Nutrients Resulting from Fermentation

Fermentation lowers the lactose content in fermented milk products; however, if the starting milk is concentrated or fortified, the finished product’s lactose content may be higher than that of liquid milk.

The composition and content of protein and total amino acids are comparable to those of raw milk. Casein degradation is small compared to cheese, accounting for not more than 1% of the total protein. While some products of casein degradation are used by the starter microorganisms, others build up as free amino acids in the fermented kinds of milk. The amounts of free amino acids that build up differ depending on the species. Generally, proline is increased in large quantities, followed by serine, alanine, valine, leucine, and histidine. As a result of continuous starter culture activity, the level of free amino acids increases during storage. A limited degree of lipolysis occurs during the manufacture of fermented milk. The amount varies depending on the type of species, but the pattern and concentration of free fatty acids are both impacted. During fermentation and the breakdown of amino acids, trace amounts of volatile fatty acids are also produced.

Being an essential component of the rich Indian past, traditional dairy products and a sophisticated classification of confections have played a significant role in the Indian economy. Depending on how it is processed, it has significant social, cultural, and economic significance. These products have been developed over a long period using a combination of experience, traditional wisdom, and culinary skills. India is emerging as the highest milk- producing country in the world with an annual production of 221.1 million tons in the year 2021–22 (Source: Basic Animal Husbandry Statistics, MoFAHD, DAHD, GoI). An estimated 50% of the milk produced in India is used to make a range of traditional dairy products, including paneer, dahi, ghee, khoa, and shrikhand. The product is not only well- established in the Indian market, but it also has significant export potential due to the large Indian diaspora living all over the world.

All native milk products that have developed over time using locally accessible technologies are referred to as traditional Indian dairy products or Indian indigenous milk products. The Indian masses’ economic, social, religious, and nutritional well- being are greatly influenced by traditional dairy products.

Classification of Traditional Indian Dairy Products

Traditional dairy products in India are typically made, packaged, and/or sold using time- honored methods without the use of machinery or meticulous documentation of the procedure. These products do, however, have several technological advantages, including their widespread appeal, reduced cost of production, straightforward manufacturing process, adoption at the rural level or collection center, large profit margin, and abundance of employment opportunities. These products are categorized according to the manufacturing principle.

One of the most consumed and well- known milk products in the Indian subcontinent is ghee. It is a by- product of tradition, prepared both at organized dairy plants and the household level for a well- established market. Ghee is traditionally made from the milk of cows or buffalo. The tetrapyrrole pigments biliverdin and bilirubin are responsible for the distinctive color of buffalo ghee. On the other hand, ghee is golden yellow due to the presence of carotenoids in cow’s milk. Ghee’s composition changes according to the kind and feeding habits of the animal and can differ from place to place and season to season.

In addition to, being a substantial source of fat- soluble vitamins, essential fatty acids, and other growth- promoting components, ghee is a rich source of energy. Its value as food for humans is enormous. Additional attributes related to medicine are present in ghee. Ghee can improve one’s physical and mental attributes and treat eye conditions like ulcers. Ghee is used in religious and ceremonial rites in addition to being consumed.

Composition

Ghee is a complex lipid composed of mixed glyceride which makes up 99–99.5% of its total content. In addition, it has trace amounts of calcium, magnesium, phosphorus, iron, copper, and fat- soluble vitamins, tocopherols, carbonyls, hydrocarbons, carotenoids, free fatty acids, phospholipid, sterols, and sterol esters

The process of making dried milk involves eliminating water from milk, primarily through spray or roller drying. It is regarded as a significant sector of the dairy industry and is made from whole cow, buffalo, or standardized milk. Skim milk powder (SMP) is made from milk after the fat has been removed whereas whole milk powder (WMP) is made from whole cow or buffalo milk

FSSA (2006) Standard Of Milk Powder According to FSSA (2006), Milk powder is the product obtained by partial removal of water from the milk of cows and/or buffalo. The fat and/or protein content of the milk may be adjusted by the addition and/or withdrawal of milk constituents in such a way as not to alter the whey protein to casein ratio of the milk. It shall be of uniform color and shall have pleasant taste and flavor, free from off-flavor and rancidity. It shall also be free from vegetable oil/fat, mineral oil, thickening agents, added flavor, and sweetening agents. It may contain food additives. It shall conform to the microbiological requirements prescribed by FSSA (2006).

Water activity, high storage temperatures, longer than usual storage times, high product moisture content, high processing temperatures, and container headspace are some of the variables that affect the Maillard reaction in dried milk.

Casein and whey proteins are the major proteins present in milk. Unlike casein, whey proteins are heat-labile. Whey protein fractions present in milk are α-lactalbumin, β-lactoglobulin, bovine serum albumin, immunoglobulin, euglobulin, and lactoferrin. β-lactoglobulin and κ-casein interact during heat treatment. When milk is refrigerated for longer than 24 h, it forms γ-casein and protease-peptone fractions.

Commercially, one of the most significant milk products is ice cream. It is a frozen product which is usually made from milk or cream that has been f lavored with fruits like peaches or strawberries, and spices like vanilla or cocoa, or with sugar or a substitute. Stabilizers are sometimes combined with food coloring. Ice cream mix typically contains 10.0% milk fat, 11.0% solids not-fat, 14.0% added sugar, and 0.3% additives like an emulsifier, stabilizer, f lavor, and color substances.

Standard of Ice Cream

According to FSSA (2006), ice cream, kulfi, chocolate ice cream or softy ice cream means the product obtained by freezing pasteurized milk prepared from milk and/or other products derived from milk with the addition of sweetening agents and fruit products, egg products, coffee, cocoa, ginger, and nuts. It may also contain chocolate, and bakery products such as cake or cookies as a separate layer and/or coating. It may be frozen hard or frozen to a soft consistency. It shall be free from artificial sweeteners. It shall have a pleasant taste and smell free from flavor and rancidity. It may contain food additives. It shall conform to the microbiological requirements as given in FSSA (2006).

Concentrated milk products are obtained through partial removal of water which increases the dry matter content of milk. The increase in dry matter content in concentrated milk is proportional to the degree of concentration. The milk concentrate may be prepared from either full-cream whole milk or fat-free skim milk.

Depending on the nature of raw material and other non-milk additives concentrated milks are classified into four broad categories.

1. Sweetened condensed milk

2. Evaporated milk or unsweetened condensed milk

3. Sterile milk concentrate

4. Reconstituted concentrated milk

Sweetened Condensed Milk

One of the earliest dairy products to be produced industrially is sweetened condensed milk. According to FSSA (2006), sweetened condensed milk is the product obtained by partial removal of water from the milk of cow/buffalo with the addition of sugar or a combination of sucrose with other sugars or by any other process that leads to a product of the same composition and characteristics. The fat and/or protein content of the milk may be adjusted by the addition and/or withdrawal of milk constituents in such a way as not to alter the whey protein to casein ratio of the milk being adjusted. It shall have a pleasant taste and flavor and be free from off-flavor and rancidity. It shall be free from any substance foreign to milk. It may contain food additives. It shall conform to the microbiological requirement as laid down by FSSA. The said product shall also conform to the following requirements

Cheese is made from milk, with the addition of cream, buttermilk, and/or whey. This basic raw material is also called cheese milk. Cheese consists mainly of casein (the major protein of milk), other milk proteins, fat, other milk components, and a certain percentage of water, which is bound. Proteins are precipitated by enzymes and/or acidification as well as heat and are separated by suitable processes from the aqueous phase. (whey, serum). Cheese is most often molded, pressed, and salted and has fungal and bacterial culture additions. colorants, herbs, spices, and other non-dairy ingredients are also added to the cheese. It is consumed either fresh or at different stages of ripening.

Worldwide, there are more than 2000 types of cheese, sometimes made by very different manufacturing processes. A classification can be based on several aspects and is done in different countries according to different criteria. A general classification can be made for three major groups:

a. Rennet or natural cheese: manufactured straight from milk by using proteolytic enzymes (rennet) and acid, with a more or less pronounced ripening process.

b. Fresh cheese or non-ripened Cheese: Quarg, fresh cheese, and white cheese are examples. Its manufacturing process is similar to that of rennet cheese manufacturing, but it has a high degree of acidity and is not subjected to a proteolytic ripening process.

c. Long-life cheese (processed cheese): it is more often made from rennet cheese and is textured by thermal treatment and made shelf-stable.

Chemistry of Creaming

After being drawn from animals, normal milk will form a cream layer on standing. Because of the difference in density between fat globules (920 kg m−3 at room temperature) and milk plasma (density 1030 kg m−3), the granules tend to rise. This causes creaming, which we often want to prevent and it enables milk to be separated into cream and skim milk. Creaming is much enhanced when the globules have been aggregated into flocculates, clusters, or granules.

Cream Ripening

This unit operation serves as an intensive preparation of the cream for the churning process. It is divided into two categories.

1. Physical ripening;

2. biochemical ripening The following criteria are influenced by the cream ripening:

• Consistency, firmness, and spreadability of butter.

• Basic water content of butter during the manufacturing process (bound water in butter, which cannot be removed by any mechanical treatment).

• Buttermilk fat content, which has to be minimized.

The melting and solidification behavior of fat depends on the attached fatty acid, which indicate the hardness of the butterfat.

Natural hardness is caused mainly by seasonal feeding of the milk animals. Winter feed with a great deal of dry feed or roughage yields a hard butterfat with a high percentage of saturated and short-chain fatty acids and few double bonds in the fat molecules.

Summer feeding (green grass) results in fat with longer chains and a higher percentage of unsaturated fatty acids with many double bonds. We therefore distinguish between summer fat and winter fat or summer cream and winter cream.

Types of Enazymes in milk

1. Endogenous and 2. Exogenous.

Three sources of enzyme in milk:

1. The blood via defective mammary cells.

2. Secretory cell cytoplasm. Some of which are occasionally entrapped with fat globules by the encircling MFGM.

3. The outer layer of MFGM is probably the principal source of endogenous enzymes in milk. The outer layer of MFGM is derived from the apical membrane of the secretory cell which in turn originates from the Golgi membrane and acts as the principal source of enzyme in milk.

General Characteristics of Milk Enzymes

1. Deteriorative character e.g. lipase (commercially most important enzyme in milk), proteinase, acid phosphatase, xanthine oxidase.

2. Preservative enzymes. e.g. superoxide dismutase, sulfhydryl oxidase.

3. As an indicator of the thermal treatment history of milk. Related enzymes are alkaline phosphatase, ϒ glutamyl transpeptidase, and lactoperoxidase.

4. Mastitis infection indicator. Related enzymes are catalase, n-Acetyl-β D-glucosaminidase, and acid phosphatase.

5. Antimicrobial activity.

6. Commercial source of ribonuclease and lactoperoxidase

Common Milk Enzymes and their Role in Dairy Industry

The salts of the milk include those constituents that are present as ions or in equilibrium with ions. The main salts of milk are phosphates, citrates, chlorides, sulfates, carbonates, and bicarbonates of sodium, potassium, calcium, and magnesium. Approximately 20 other elements are found in milk in trace quantities including copper, iron, lead, boron, manganese, zinc, iodine, etc. These ions are more or less associated with themselves and with proteins. Some metals act as catalysts in the oxidation of milk fat leading to oxidative rancidity and certain metals like Ca, P, Mg, Mo, Co, Fe, etc. are components of metalloproteins such as lactoferrin, lactoperoxidase, xanthine oxidase, and parts of phospholipids.

Distribution of Salts Between Casein Micelles and Serum

The phosphorus is present as orthophosphate, but part of it is bound to organic components like serine and threonine residues of casein, molecules of hexoses and glycerol, phospholipids, etc. Phosphorus is also found in the hydroxyapatite structure of the colloidal calcium phosphate in the micellar structure of casein. The sulfur content of milk is about 0.36 g/kg, but most of it is in the amino acid residues methionine and cysteine of the proteins. About 10% is present as inorganic sulfate.

Physical Equilibria Among Salts

Milk contains several elements but all of them are not entirely in a soluble state. Some minerals exist in colloidal and ionic states at the normal pH of milk. The compounds that are in soluble condition play an important role in keeping various milk constituents in stable condition. A balance exists between the components that are in a soluble state and those which are in colloidal state.

Milk lipids or milk fats exist as an emulsion of small spherical droplets called milk fat globules. These globules are very small in size but very large in number. The diameter of the milk fat globules ranges between 0.1 and 22 µm and the number varies between 1.5 and 3.0 billion globules/mL. The average size of milk fat globules ranges from 2 to 5 µm. The average fat globule size in cow and buffalo milk are 3.4 and 4.5 µm, respectively. The surface of the milk fat globules is coated with an adsorbed layer of material known as the milk fat globule membrane (MFGM). MFGM contains phospholipids and proteins in a complex form. MFGM has two main functions (a) fat globule stabilization and (b) preservation of the fat globule’s identity.

General Composition

Triacylglycerols (triglycerides) represent 97–98% of the total lipids in the milk of most species. The diglycerides probably represent incompletely synthesized lipids in most cases. Although phospholipids represent less than 1% of total lipids, they play an important role in being present mainly in the MFGM and other membranous material in milk. The principal phospholipids are phosphatidylcholine, phosphatidylethanolamine, and sphingomyelin. Trace amounts of other polar lipids, including ceramides, cerebrosides, and gangliosides, are also present. Phospholipids represent a considerable percentage of the total lipid of buttermilk and skim milk reflecting the presence of proportionately larger amounts of membrane material in these products.

Carbohydrates are polyhydroxy derivatives of aldehydes or ketones and undergo all the organic reactions common to the carbonyl groups and hydroxyl groups. The principal milk carbohydrate is lactose. It is a disaccharide. Hydrolysis of lactose with enzyme β-galactosidase yields glucose and galactose.

Lactose is the major carbohydrate present in all types of milk. The first record of isolation of lactose was in 1663, by Bartolettus by evaporation of whey. Milk contains only trace amounts of other sugars, including glucose, fructose, glucosamine, galactosamine, neuraminic acid, and neutral and acidic oligosaccharides.

Lactose plays a significant role in milk and milk products that are

• It plays a major role in the production of fermented dairy products.

• It contributes to the nutritive value of milk and milk products

• It affects the texture of certain concentrated and frozen products;

• It is involved in heat-induced changes in the color and flavor of highly heated milk products.

Status of Lactose

Lactose content varies extensively in the milk of different species. Breed of animal, individuality factors, udder infection, and especially the stage of lactation regulates the lactose content in milk. The lactose concentration in milk decreases gradually and significantly during lactation; this behavior contrasts with the lactational trends for lipids and proteins, which, after a decrease during early lactation, increase significantly during the second half of lactation. Lactose synthesis is hampered during mastitis. Lactose, along with sodium, potassium, and chloride ions, plays the principal role in controlling the osmotic pressure of the mammary system. Thus, any change in lactose content is compensated by a change in the soluble salt constituents. The osmotic relationship between lactose and soluble salts during the secretion of milk partly explains the presence of high lactose in milk with a reduced ash content and vice versa (Table 1).

Bovine milk contains an average of 3.5% protein. The concentration of protein changes significantly during lactation. The first few days of lactation exhibit the main change in protein concentration. The main changes occur in whey protein fraction.

Distribution of Protein in Milk

80% casein and 20% whey protein (β lactoglobulin- 10%, α- lactalbumin- 5%, serum albumin, and immunoglobulin- 5%).

Fractionation of Milk Proteins Fractionation of milk protein is mainly done by acidification at pH 4.6 around 30 °C.

Almost 80% of the bovine milk protein precipitates at pH4.6, and this fraction yielded by precipitation is called casein.

The remaining soluble part of the protein is referred to as whey protein/serum protein/ non- casein protein. Wide variation is observed in the casein- whey protein ratio in different types of milk(protein synthesis is independent of animal diet)

Significant Difference Between Casein and Whey Protein

1. Casein precipitates at pH 4.6 but does not precipitate whey protein at that pH. This property of milk protein is commercially exploited for the preparation of industrial casein and certain varieties of cheese.

2. Chymosin or other proteolytic enzymes produce specific changes in casein resulting in coagulation in the presence of calcium. Whey protein does not undergo this type of coagulation.

3. Casein is very stable to high temperatures. They can withstand heating up to 140 °C for 20 minutes but whey protein is relatively heat labile. They are completely denatured by heating at 90 °C for 10 min.

4. Casein is a phosphoprotein containing an average of 0.85% phosphorous while whey protein does not contain any phosphorous. The phosphate of casein is an important contributor to remarkably high heat stability and calcium- induced coagulation of rennet- altered casein.

5. Casein contains very low sulfur (0.8%) whereas whey protein is relatively rich in sulfur (1%). The principle casein contains only methionine but whey protein contains a significant amount of cystine, cysteine, and methionine. These sulfur- containing amino acids are responsible for many changes in milk on heating.

6. Casein is synthesized only in the mammary gland and no other sources in nature. Some of the whey proteins β lactoglobulin, and α- lactalbumin are synthesized in the mammary gland but bovine serum albumin and immunoglobulin are not synthesized in the mammary gland but derived from blood.

7. The whey protein is dispersed in solution and has a simple quaternary structure. Casein has a complex quaternary structure and exists in milk as large colloidal aggregates.

Introduction

The mammary glands of female mammals secrete milk, a necessary food that is liquid and meets the newborn’s nutritional needs. All mammals consider milk to be a complete food for their newborns. It is considered a necessary food for humans and can be consumed as a product or as liquid milk. It contains almost all essential nutrients except iron, which is very low in milk. In essence, milk is an emulsion of protein and fat in water, supplemented with carbohydrates, vitamins, and minerals.

Definition of Milk

• Milk is a complex biological fluid that differs from species to species in both composition and physical properties. It is the full lacteal secretion of a mammary gland that is obtained by milking mammals for a minimum of 72 h after calving or until the milk is free from colostrum.

• FSSAI defines milk as the normal mammary secretion derived from the complete milking of healthy milch animals. It should be free from colostrum.

From a chemical perspective, milk is a dynamically balanced mixture that comes in different forms such as emulsion, colloidal suspension, and true solution. It also contains varying amounts of proteins, fats, carbohydrates, salts, and water.

Gross Composition of Milk

Milk composition varies among different mammals. The average chemical composition of milk in various species is given in Table 1. Buffalo milk and sheep milk contain higher amounts of fat, while human milk comparatively has the highest lactose content. Human milk has lower protein content as compared to milk of other species.

Introduction

Export of quality seafood products is important to have a success in international marketing. Exporters must be quality conscious and the Governments must insist on quality control and inspection. The seafood export industry in India is over 50 years old. Seafood contributes 10% of the total exports and nearly 20% of all agricultural exports. In the year 2022-23, India exported 17,35,286 MT seafood to more than 100 countries worth US $8.09 billion equivalent to Rs. 63,969.14 crore. There are over 150 fish processing facilities approved by the European Union out of the existing 350 processing facilities. The Export Inspection Council and the Marine Products Export Development Authority are working very closely with the fish processing industries for the growth of seafood exports.

The Government of India enacted the Export (Quality Control and Inspection) Act, 1963 for the development of export trade through quality control and inspection. It empowers the Government to notify the products intended for compulsory quality control and inspection prior to their export. It specifies the type of quality control required for the notified products. It recognizes standard specifications for a notified product. It prohibits the export of notified products that are not complying with export conditions. It creates a machinery for quality control and take measures to protect markets for Indian commodities. As the first step, Export Inspection Council (the Council) was established on 1st January 1964 for implementation of various provisions of the Export (Quality Control & Inspection) Act, 1963.

Introduction

Wastes produced during fish processing operations can be solid or liquid. Solid wastes consist of skin, viscera, fish heads, fish bones, and scraps of f lesh. Liquid wastes are the blood water and brine from drained storage tanks, water discharges from washing and cleaning, blood and soluble substances from entrails, and detergents and other cleaning agents. The effluent from the processing of fatty fish contains very high levels of oil. Overall, the wastewater from fish processing operation contains an undefined mixture of substances, mostly organic in nature.

13.1. Physicochemical Parameters of the Wastewater

13.1.1. pH

The pH is an important parameter that reveals contamination level before biological treatment. The effluents from fish processing plants are usually close to 7 or alkaline, due to decomposition of the proteinaceous matter and emission of ammonia compounds.

13.1.2. Solids Content

Solids may be present either in dissolved or suspended form. Suspended solids are objectionable as they settle in the wastewater ducts reducing their capacity or settle in the waterbody affecting bottom - dwelling flora or sometimes float reducing the light entering from the surface or remain suspended reducing the amount of light that enters the water. The settling solids are measured using an Imhoff cone. If the wastewaters contain solids that settle after 10 min, their discharge is usually not permitted. The suspended solids are measured by passing a sample through a fiberglass filter; and determining the quantity by gravimetry, after evaporation of a known volume of the filtrate.

Introduction

Seafood provides about 25% of the global intake of animal protein and fetches a huge economy for developing nations. Many challenges concerning food safety and quality exist due to globalization and liberalization of the global f ish trade. International food safety regulatory bodies such as WTO and CAC through SPS and TBT Agreements work on ensuring food safety and quality. Adoption of risk-based analysis and implementation of the HACCP system are encouraged to maintain high seafood safety standards. International regulatory bodies set maximum residual limits for various environmental pollutants and contaminants to ensure consumer safety. Consumer education programs play important role to enhance awareness and improve transparency in the seafood supply chain. Internationally traded seafood products therefore need to meet the standards prescribed for food safety and quality requirements. In case of non-conformance, they could be detained, rejected and destroyed.

The global demand on seafood quality and safety requirement and the complexities of seafood supply chain make difficulty to ensure authenticity and traceability of seaood products in the market. Most seafood is exported from the country where it is caught while part of it via. a third country. Seafood pass-through complex supply chains involving, capture/culture, transshipment, processing, packaging, wholesale, retailing, and consumer. The global trade of seafood has led to a significant concern associated with seafood fraud.

12.1. Seafood Fraud

Seafood fraud is the practice of providing misleading information to the consumers about their product for financial gain. There are nine types of seafood fraud, which include species substitution, fishery substitution, IUU substitution, species adulteration, chain of custody abuse, catch method fraud, undeclared product extension, modern day slavery, and animal welfare

Introduction

Nutrition is the study of how food and nutrients affect the body’s health and well-being. It encompasses all aspects of food, from the food production, processing, consumption and digestion by the body. A balanced diet included all the essential nutrients such as carbohydrates, protein, fat, vitamins and minerals for maintaining good health. The recommended daily intake of nutrients varies depending on the age, gender and physical activity of a person. The nutritional need also varies depending on the lifestyle and medical condition of a person. The nutrition facts are based on recommended daily intakes for various nutrients, which vary based on factors such as age, sex, and physical activity. These facts are given on food packaging or label, providing important information on the serving size, calories, macronutrients and micronutrients, and other ingredients.

Nutrition labels are mainly intended to guide the consumer in food selection. Nutrition information provided on labels must be true and should not mislead consumers. Nutrition labelling regulations are provided by countries to help manufacturers. The Codex guidelines on Nutrition Labelling provide guidance to member countries to develop or update their national regulations and to encourage harmonization of national standards with international standards. According to it, no food should be described or presented in false, misleading or deceptive way. Nutrition labelling cannot solve nutrition problems, instead it is one of the elements of nutrition policy.

11.1. Nutrition Facts

Nutrition Facts means the nutritional information required for most of the packaged food in many countries giving the energy value and nutrients contained in the food. Nutrition facts labels are required by regulation similar to other types of food labels. It provides detailed information on the nutrient content of the food such as the amount of fat, sugar, sodium and dietary fiber.

Introduction

The international fish trade increases day by day reaching to a tune of USD 151 billion in 2020 (FAO, 2022). Many developing countries like India gain benefits from this trade as income through net foreign exchange reached to a level of 8.09 billion USD in 2019-20. Seafood supplied by developing countries contribute to 77% of fish consumption worldwide. The European Union (EU) is the single largest market for fish and fishery products to a tune of 91.74 billion USD in 2022 as a consequence of an increased per capita consumption among its Member States. Spain, Italy, Germany and the United Kingdom are the largest importer of fish and fishery products.

To protect consumer health and to protect the territory from the introduction of animal and plant diseases, the European Community (EC) has laid down joint conditions for imports of foodstuffs. The Directorate General for Health and Consumer Protection (DG SANCO) is responsible for food safety in the EU. The import rules for fishery products are framed of high standards with respect to hygiene, consumer safety and animal health status. It is important that importing countries and food business operators (FBOs) must understand the fundamental principles and requirements of the European Food Law to ensure efficient and smooth imports. The EU system relies on Government to Government assurances without any intervention of any private type certification or standards. The Competent Authority (CA) in the country of origin is responsible for giving the official guarantees to the EU regarding compliance and conformity to all requirements of its legislation. The Export Inspection Agency (EIA) is the Competent Authority in India for issuing the required official guarantees for export of fish and fishery products. The EIA maintains a complete list of all establishments under its control.
