Pineapple is a monocarpic perennial herb. Each stem flowers only once and dies after fruiting, similar to bananas, before a side shoot takes over. After the pineapple plant reaches a certain size, natural inflorescence initiation (flowering) occurs in response to decreasing day length and temperature (Bartholomew, 2003). Flowering of Smooth Cayenne pineapples grown under an 8-hour day length was encouraged by a night temperature of 20°C, whereas f lowering was delayed by temperatures of 15 and 20°C, and totally inhibited by 30°C.Flower initiation usually starts in November and lasts through the winter. Flowering in nature is highly irregular, and some plants can fail to produce fruit. Thus, growth regulators such as ethylene (25-50 ppm) and NAA (25 ppm) are used in industrial practise to force plants to bloom. The numerous radish-purple sessile flowers are spirally arranged on the axis, each with a pointed bract. To explain the emergence of developing inflorescence, this stage is also known as the red bud stage. The spike-like inflorescence contains 100 to 200 florets. The petals are white at the base and bluish-purple above the calyx at anthesis. They are ligulae form in shape, about 1.6 cm long and 5 mm wide, and are about 1.6 cm long and 5 mm wide (Collins, 1960).The outer f lower petals are very close together, allowing only small insects to reach the f lower; they have 14 to 20 locules, resulting in a capacity of 6000 to 7000 seeds per 150 floret fruit. After pollination, fruits with 2000 to 3000 seeds are not uncommon (Collins, 1960).

Research methodology gives detailed justification about the research methods and procedures carried out in the present study. The present study focuses on the women’s involvement in the dairy farming and their empowerment. Keeping in view the specific objectives of the study and various aspects relating to these objectives the methodological framework has been formulated. The sub topic under the research methodology is as follow:

3.1 Locale of the study

The present study entitled “Retrospective Multidimensional Study on Magnitude of Participation of Women in Dairy Farming in East district of Sikkim” was carried out in the villages of East district of Sikkim. Sikkim is the second smallest states in India, with an area of 7,096 sq. km in size. The meaning of Sikkim is “The valley of rice”. It lies between 27 º33' 00" N and 88 º30' 00" E. The average annual temperature of the state is 18 ºC (64 ºF) and annual rainfall is 2739 mm. The state is situated in the Eastern Himalayas and it shares its border with countries like Tibet, Nepal and Bhutan. Mt Kanchendzonga (8585m) which is the third highest peak in the world is situated at Sikkim. According to 2011 census, population of state was 610,577 with male population of 323,070 and female population of 287,507. The literacy rate in the state is 81.40 percent. The density of the state is 86 people per km2 (Census,2011). The cattle population in the state was 264,860 in number (BAHS,2019). The state has four district- East, West, North, and South (Registrar General of India, 1989).

Several fruits and vegetables are unexploited for proper utilization and product development. Due to lack of utilization, there is a lot of wastage and ultimately the great loss to the people as well as nation. Some unexploited fruits and vegetables have potential for introducing new products. Therefore unexploited fruits and vegetables have to be exploited for new product development especially from underutilized sub-tropical and tropical fruits and vegetables. Research and development should be undertaken to utilize these fruits and vegetables.

Unexploited Fruits

Unripe Green Mango: Although pickles are prepared but droped green mango fruits are not preferred for pickle preparation. They can be dried and utilized for preparation of dried slices or amchur. Amchur is used to develop flavor and taste in Ice cream. These products are used to develop flavor and taste in meal or food. It is also used to prepare chatney. But utilization of Amchur is not known to common people.

Avocado: It is found in tropical and sub-tropical climatic regions having more humidity and rainfall. In Ethiopia it is found throughout the country but not utilized properly by people. They prefer to eat ripe fruits with salt and lime juice. It is very healthy fruit for chronic disease like cardiac and diabeted diseases. This is seasonal use but no product is available for off season. Therefore researches should be carried out for different products development of Avocado products.

Research and development plays a central role in innovation, product improvement, cost optimization, and competitiveness in the ice cream industry. This chapter explains the distinction between research, development, and new product development and examines the responsibilities of an R&D department. It covers formulation development, pilot and plant trials, ingredient evaluation, shelf-life studies, regulatory considerations, supplier collaboration, product costing, and commercialization. The chapter also highlights the importance of cooperation between R&D, QA, production, procurement, marketing, and finance. Key performance indicators and common mistakes are discussed to strengthen the effectiveness of R&D programmes. The chapter ultimately connects scientific innovation with manufacturing feasibility, consumer expectations, regulatory compliance, and commercial success

It is a most deteriorating biological process of the harvested fruits and vegetables that leads to the oxidative breakdown of the complex material (carbohydrates or acids) of cell into simpler molecules (CO₂ & water) with production of energy. Respiration includes glycolysis metabolism, aerobic metabolism, anaerobic metabolism, trycarboxilic acid cycle and electron transport metabolism processes.

India is situated north of the equator between 8°4' and 37°6' north latitude and 68°7' and 97°25' east longitude, is the largest peninsular country in the world bordered by Arabian Sea in the west, Indian Ocean in the south and the Bay of Bengal in the east. India has a coastline of 8118 km and 0.5 million t sq. km continental shelf endowed with 2.02 million sq. km of Exclusive Economic Zone (EEZ). It has a catchable annual fisheries potential yield of 4.41 million occupying third rank in world marine fish production (Table 1). India’s territorial waters extend into the sea to a distance of 12 nautical miles from the coast baseline. The vital details on marine capture fisheries of India are given in table

This chapter presents the analysis, interpretation and discussion of the collected data from the study area in an effort to attain the objective of the study. The data collected were analyzed with appropriate statistical test and presented in a systematic format.

The results of the study are presented under the following subheadings:

4.1 Distribution of respondents according to different socio-economic variables

Basic information of the respondents under the study has been given according to the socio-economic characteristic of the respondents. Variables like age, education, marital status, family size, family type, milk production per day, social status, farming experience, herd size, land holding and annual income are presented in the following table 4.1

1.1 Introduction
The rural economy has greatly benefited from dairy farming. In rural India, milk has become a substantial source of revenue. Dairy products, including milk, are vital components of modern diets. India holds the title of being the greatest milk producer and consumer globally. Together with native cattle, crossbred cattle, and water buffalo, it also has the biggest dairy herd. Since 2000, there has been a steady and substantial annual growth rate of 4.2 percent in both milk production and consumption. Additionally, second, respectively, in terms of population (GoI, 2014). It accounts for around 25% of the global bovine population. India has emerged as the leading global producer of milk, with a remarkable production of over 155.5 million tonnes during the 2015- 16 period. This translates to a per capita availability of 337 grammes per day, according to the Government of India (GoI, 2017). Dairy farming serves as a primary means of subsistence for more than 100 million individuals. A significant percentage of small-scale livestock keepers lack access to land, and the prevalence of rural landless households is expected to rise due to the continued subdivision of land holdings. Livestock are increasingly vital for the income of smallholder and landless farmers. These initiatives have positively impacted the farmers’ food production, nutrition security, and household income. Additionally, they have played a crucial role in creating employment opportunities in rural areas.

In spite of big potential of the largest livestock population in the world, meat industry in India is still in nascent stage. It is a business of those who are not trained and very much literate. The industry is primarily based on the raw material that is not reared for meat purpose but serves the secondary role after passing their viable life in primary field. The industry is also facing problem of social prejudice and meat is taboo for certain communities. But scenario is now changing and people are coming forward to organise the sector. Now the society is accepting the facts that meat is an only source of cheap and nutritious food to million of people in India and the good source of animal protein for large segment of Indian population, particularly landless, small and marginal farmers.

India ranks fifth in the world meat production with the annual meat production of about 6.3 million tones which is 2.21% percent of world meat production. In the last two decades meat industry in India has grown @ 4.5% whereas, during the last five years, this segment has been growing very fast at the rate of 27% annually. It has a good future if given proper attention by the Government and Private Entrepreneurs. In total meat production, share of cattle is 17.34%, buffalo 23.3%, sheep 4.6%, goat 9.4%, pigs 5.3%, poultry 36.6% and others 3.4%. The share of various meat types in total Indian meat production accounts buffalo meat 1.5 million tones, beef 1.28 million tones, mutton 0.24 million tones, chevon 0.53 million tones, pork 0.50 million tones, chicken meat 2.20 million tones and duck meat 0.07 million tones. To produce the above quantities, the extraction or slaughter rates in cattle are about 7.9%, buffaloes 11.1%, sheep 47.9%, goat 37.9%, pigs 88.9% and poultry 73.6%. In the world total meat production Indian cattle meat shares 13.1%, buffalo meat 55.8%, mutton 5.7% and chevon 14.9%. However, India is having world’s 15.0% (210 million) cattle, 57.0 %( 111 million) buffaloes, 7.0 %( 74 million) sheep, 17.0 %( 154 million) goat and 1.5% pigs. Overall contribution of meat sector in total output of Livestock sector was Rs 25984 crores in the year 2004-2005.

Research being a continuous process for a scientific study, previous study provides basis for the research. The review of literature is necessary for developing conceptual frame work and suitable design for the study. It assists the researcher to keep his work going in right direction. The available literature related to the present study has been reviewed under the following heading:

2.1 Differential role accomplished by women dairy farmers from different social strata

Toppo et al. (2004) examined the participation of women farmers in dairy occupation in Anand district of Gujarat and their result revealed that 18.34 percent of the farm women were mostly engaged in activities related to artificial insemination, majority of the respondent (68.34%) participated in cleaning of the shed, while 25.00 percent of the farm women practised manure preparation and 95.00 percent of the respondent were not involved in preparation of gobar gas mixture.

Badole (2006) reported that majority of the responded had low socio-economic status.

Millets are essential grains that help developing nations in Asia and Africa’s semi-arid tropics, particularly India, Nigeria, and Niger, achieve food and nutrition security.They are grown on soils that are usually too weak for any other crop to grow. They can withstand drought, minimal fertiliser treatment, and temperature swings better than other cereal crops, and their short growing season makes them exceptional. Millets are all-season crops that can be grown all year and provide several security benefits (food, feed, health, nutrition, livelihood, and the environment), making them the most cost-effective agricultural security crop. Sorghum (Great millet), Bajra (Pearl millet), small millets such as Korra (Foxtail millet), Ragi (Finger millet), Kodo millet, Proso millet, Little millet and Barnyard millet are all important millet crops grown in India.

Introduction

Food processing comprise of techniques employed to transform raw ingredients into final food product or to preserve the food product. Food processing industry as well as at domestic scale the food processing methods aim at providing processed food products for daily consumption by humans and animals. Food processing aims at increasing the shelf life, preserve, make nutritious or ready to eat foods, and getting the best quality final products. There are various techniques and methods which come under food processing such as drying, dehydration, fermentation, pickling, freezing, mixing, pumping, pasteurization, cooking and homogenization etc.

Rheological properties of foods are greatly influenced by various unit operations and processing methods or conditions such as heating and mechanical treatments. Processing of different food products such as dairy, fruit and vegetable products like jams and purees, chocolates, dough development etc. and basic make up of foods such as fats, proteins and others such as emulsifiers, hydrocolloids etc. affects the rheological properties of food product and which ultimately affects the quality of end product. Apart from processing conditions the compositional variations have a great impact on the textural or rheological properties of foods. The changes in rheological characteristics of a food product reflects the alterations in the molecular structure of the food material, this can aid in revealing the changes in product structure during different processing methods or conditions. In designing of various processes such as cooling, freezing and equipment design information about thermal properties is crucial. Moreover, in order to design storage structures for foods and refrigeration equipment the knowledge of thermal properties is important (Becker et al. 2003).

For rheological measurements various tests and techniques are available, such as steady and dynamic shear measurements. From the steady shear properties flow properties of the sample can be revealed whether the flow is Newtonian or Non Newtonian. In case of dynamic shear rheological properties information on viscoelastic characteristics can be withdrawn in terms of storage and loss modulus and depending on the predominance of each modulus the nature of sample can be predicted i.e. whether viscoelastic solid or viscoelastic fluid (Bhardwaj et al. 2019). Apart from these measurements, other rheological measurements are available for specific food materials, such as farinograph, alveo-consistograph, mixograph etc. are meant for study of rheological properties of dough. So, accordingly, depending upon the food material choice of rheological measurement can be made. To study the thermal transitions DSC (Differential scanning calorimeter) and DTA (Differential thermal analysis) are commonly employed. Dynamic measurements as a function of temperature or time are made in these techniques to detect the endothermal and exothermal changes. These techniques can be used to determine the phase transitions in various foods, for instance, crystallization and melting of water, lipids and other food components; denaturation of protein; gelatinization of starch and others (Roos 2015).

1. Introduction

Celiac disease (CD) is an immune-mediated enteropathy triggered by the ingestion of gluten in genetically susceptible individuals. Gluten is the protein component in wheat, rye and barley. In the last 10 years, cutting edge scientific developments in this disease have led to the formulation of new concepts of epidemiology, pathophysiology and clinical manifestations. At present, the only available treatment for CD is a strict gluten-free diet (GFD) (Mulder et al., 2013; Theethira and Kelly, 2014). Until recently, the geographical distribution of CD was mostly restricted to Europe and other developed countries, such as the United States, Canada and Australia. Celiac disease is not only frequent in developed countries, but it is increasingly found in areas of the developing world, such as North Africa (Malekzadeh et al., 2005), Middle East (Rostami et al., 2004) and India (Basu et al., 2014, Deora et al., 2014; Yachha and Poddar, 2007). New epidemiological studies have brought evidence that this disorder is common in many developing countries as well, showing that the ‘global village of celiac disease’ has indeed a worldwide distribution (Fasano and Catassi, 2001).

The only available treatment for celiac disease is the strict, lifelong avoidance of gluten. When gluten is removed from the diet, the small intestine will start to heal and overall health should improve (Fasano and Catassi, 2001). Traditional substitutes for gluten-containing grains have been rice, tapioca, corn, and potato. However, more nutrient-dense grains, seeds, nut flours, and legumes are being incorporated into the diet to provide an enhanced palatability, variety, and nutritional quality. These include sorghum, millet, teff, quinoa, amaranth, flax seed, and buckwheat.

Ripe

This word is derived from Saxon word ‘Ripi’, which means gather or reap. This is the condition of maximum edible quality attained by the fruit following harvest. Only fruit which becomes mature before harvest can become ripe.

Ripening

Ripening involves a series of changes occurring during early stages of senescence of fruits in which structure and composition of unripe fruit is so altered that it becomes acceptable to eat. Ripening is a complex physiological process resulting in softening, colouring, sweetening and increases in aroma compounds so that ripening fruits are ready to eat or process. The associated physiological or biochemical changes are increased rate of respiration and ethylene production, loss of chlorophyll and continued expansion of cells and conversion of complex metabolities into simple molecules.

A healthy life is ensured by having access to safe, nutritious and balanced food. World health organisation (WHO) ensures its contribution in developing food safety systems that are sustainable to reduce health risks from farm to consumer. Thus, safe food, its quality and consumer protection are the priorities of this organisation (FAO and WHO, 2021)

Introduction

Biological, physical, chemical and other hazards associated with food have been detailed in Chapter 4. This chapter would address the risks associated with these hazards as well the scientific approach is assessing them. Risk analysis is an inevitable platform for food safety assurance which measures the impact of hazards on the health of consumers. To improve public health and maintain consumer trust in the food supply and to provide a sound regulatory foundation for national and international trade in food, an efficient food safety management system is essential. Therefore, World Trade Organization (WTO) developed food regulations governing international trade in foods based on science and risk assessment. A sound knowledge of food hazards and risks they pose to consumers, along with the capacity to take appropriate interventions, deserve top priority of a responsible authority and industry.

Risk

The word ‘risk’ is used to describe a situation that involves a possibility of something undesired to happen (Rowe, 1977). In food processing, hazards are considered as risks. Hazards are often thought of as synonyms of risks, however, hazards are quite different from risks.

A food borne hazard is defined by Codex as “a biological, chemical or physical agent in or condition of food, with the potential to cause an adverse health effect”. A risk is the chance, low or high, that any hazard will actually cause harm. Some of the emerging food hazards that must be assessed and managed are listed in table 1. Assessment and management of risks posed by these hazards is the responsibility to be urgently addressed by the scientific community.

Introduction

The risk assessment is gaining importance as the scientifically-based approach for the development of food safety and quality standards. It is a logical extension of HACCP revolution. In hazard analysis, first the hazards likely to occur in foods are identified, then an assessment is made of the severity of each hazard, and an evaluation is done of its likelihood to occur. Severity and likelihood are the two factors involved in risk assessment. Second, the increase in international trade has raised new safety and quality challenges. New approaches address the risk of cross-border transmission of infectious and hazardous agents with emerging food-borne diseases and quality problems. This has led to the development of a new safety and quality regulatory framework in 1995, the Sanitary and Phytosanitary (SPS) and the Technical Barriers to Trade (TBT) Agreements of the World Trade Organization (WTO). In these two Agreements, two provisions are of importance to fish safety and quality:

• National SPS and quality requirements should reflect standards agreed on in the international standards setting bodies i.e. Codex Alimentarius for food quality and safety.

• Domestic standards can be developed based on scientific risk assessment.

Risk assessment of microbiological hazards is identified as a priority area by the Codex Alimentarius Commission (CAC). In 1999, the Codex Committee on Food Hygiene (CCFH) in the 32nd session, identified a list of 21 pathogen commodity combinations that require expert risk assessment advice. FAO and WHO jointly launched a programme with the objective to provide an expert advice on risk assessment of microbiological hazards in foods to their member countries and to the CAC. Under which, expert groups are established to examine four priority pathogens: product pairings, e.g. Listeria monocytogenes in ready-to-eat food; Salmonella in eggs and broiler chickens; Campylobacter spp. in broiler chickens; and Vibrio spp. in seafoods. Risk assessment is therefore important throughout all aspects of the seafood industry - for companies, national governments and for international regulators.

9.1 Introduction

Food quality and safety are central issues in food economics today. A number of developed countries (EU, UK, US) has imposed a number of new regulations to track food products across the supply chain which is forcing the companies to invest in new automated approaches for their implementations. These solutions facilitate better process efficiency with more productivity, quality control in production lines, lower manufacturing costs with higher profit margins, and also help to achieve improved presentation as customers request. The high labour costs in developed countries make cost-cutting inevitable to remain competitive production. The growth in products packaged for the market, the increasingly strict hygiene regulations, the need to reduce risks at work, cut costs, and control product quality are all calling for the development of technologies that enable robots to be used for these tasks. In fact, robotics has a great opportunity in this industry. But the variation in physical properties of various food products and the necessity to avoid damaging them, make it necessary to seek flexible handling solutions for a wide range of products.

The robotics industry is looking into a bright future. As per the report given by the Statistical Department of International Federation of Robotics (IFR), it was projected that between 2014 and 2016 worldwide robot sales will increase by about 6% on average per year. Ten years ago, global sales figures were hovering around 80,000. So, three key factors for the boom - factory modernization, increases in production capacity and rising demand from a number of emerging markets.

Calcium, anti-oxidants and certain enzymes are reported to play vital role in extending the shelf-life of harvested produce of many horticultural crops especially fruits. They help in maintenance of cell wall structure. Being an important constituent of cell wall, in the form of calcium pectate, it helps in maintenance of cell wall structure. Antioxidants are highly beneficial in extending the shelf-life of fruits besides maintaining the quality. Similarly, some enzymes play a key role in preserving the fruit quality and prolonging its market life. As some fruits are catergorized under ‘Low volume high value fruits’, it is essential to extend their shel-flife for reducing the post-harvest losses of fruits and also to reap better remuneration. Thus, it becomes indispensable to review the role of Ca, anti-oxidants and enzymes which are beneficial in keeping the harvested produce afresh for a relatively longer period.

Abstract

Research has demonstrated that nutrition plays a crucial role in the prevention of chronic diseases as most of them can be related to diet. Functional food enters the concept of considering food not only necessary for living but also as a source of mental and physical well-being contributing to the prevention and reduction of risk factors for several diseases or enhancing certain physiological functions. One of the most clear objectives of the study of functional foods is to identify and validate biological markers in order to understand the interaction mechanisms between the food component and a body function. Epidemiologic and laboratory data from previous studies suggests that diets rich in fruits and vegetables are associated with a reduced risk of various types of cancers. The reduction in cancer risk may be attributed to the abundance of a family of specific compounds referred to as anthocyanins, which are found in various berries. Anthocyanins are water soluble pigments responsible for the blue, purple, and red color in many plant tissues Strawberry is one of “super fruits”, since they can form a significant component of the diet and are a potential resource of functional foods and nutraceuticals due to their antioxidant capacity and nutritional quality. Strawberries contain high levels of anthocyanins and they are also well liked by consumers. Popularity of strawberries in the consumer market makes them an ideal focus for chemoprevention studies. Strawberries are a rich source of phytochemicals (anthocyanins, catechins, the flavonols quercetin and kaempferol, and ellagic acid) and an important source of essential nutrients (ascorbic acid, potassium, folic acid, carotenoids, B-vitamins). Strawberries are consistently ranked among the top food sources of polyphenols and antioxidant capacity; the preventive and therapeutic health benefits of strawberries may be attributed to the synergistic effects of these bioactives and the nutrients contained in the fruit. These bioactive photochemical contribute the major health-promoting function. Strawberries have shown a remarkably high scavenging activity toward chemically generated radicals, thus making them effective in inhibiting oxidation of human low-density lipoproteins. Antioxidant activity of strawberries could contribute to the prevention of cancer, cardiovascular and other chronic diseases. Hence strawberry can be used as a vital and indispensible functional ingredient for the development offunctional foods and nutraceuticals.
