Abstract

Determination of quality of wheat is very important because quality requirement of an individual product vary from one another. Flour quality can be defined as the ability of the flour to produce a uniformly good end product. Flour quality factors can be divided into two basic groups: those that are inherent in the wheat as a result of the genetic make up and the changes brought about by growing conditions; secondly those factors that might be altered during the process of converting wheat into flour Wheat flour constituents play an important role in determining the quality of flour. The flour quality for baking could be assessed by measuring the physical, chemical and rheological characteristics.

Wheat (Triticum aestivum L.) is one of the major cereal consumed globally in various form as food. The powder of wheat flour is prepared by grinding of wheat seeds. Soft wheat flour has low gluten content that causes its crumbly texture. However, hard wheat flour has high gluten content of about 12-14% and has elastic toughness due to which it has good shape once its baked. Wheat flour is a basic ingredient in India’s famous flatbreads, and it can also be a key ingredient in addressing major health concerns in India.

Quality management in apparel production requires an integrated approach covering every stage from material sourcing to final inspection. Important areas include fabric inspection, spreading, cutting, in-process monitoring, finishing and evaluation of completed products. The chapter explains the Acceptance Quality Limit system through practical examples and introduces Statistical Process Control for monitoring manufacturing performance. It aims to help students, practitioners and researchers understand the multiple dimensions of apparel quality and apply appropriate inspection systems. Checklists, performance indicators and corrective measures support continual improvement. Because perceptions of quality depend on value, expected performance and durability, manufacturers must translate customer expectations into measurable specifications and consistently controlled production processes.

Fruits and vegetables are very important food commodities not only in developing country like India but all over the world. India, which is the most densely populated country in Asia continent, is still struggling to achieve self-sufficiency to feed about 135 crores people. For this purpose, fruits and vegetables have got their specific importance to provide a balance and healthy diet to the Indian people. Therefore, the reduction of post-harvest loss of fruit and vegetables is a complementary means for increasing production. It may not be necessary to considerably step up the production of fruits and vegetables with the growing demand if the post-harvest loss is reduced to a great extent. The cost of preventing losses after harvest in general is less than preventing a similar additional amount of fruit and vegetable crop of the same quality

Fruits are important source of Pro-vitamin A and vitamin C. In addition, vegetables also supply fair amount of carbohydrates, protein and energy and add colour, flavour and aroma to human diet. India is one of the largest producers of fruits and vegetables. Fruits and vegetables are an important supplement to the human balanced diet as they provide the essential minerals, vitamins and dietary fibre (roughage) for maintaining the tear and wear of the over body. Fresh fruit and vegetables have a short shelf life under ambient conditions of temperature and humidity due to their highly perishable nature. They soon lose their freshness and become subjected to mould and bacterial attack, and consequently decay and become useless as articles of human diet. Fresh fruits and vegetables are valued for their quick sources of available energy. Fresh fruits have high water content (70-96%), varying amount of carbohydrate (3-27%) and fibre (0.2-3.1%) and a low content of protein, fat and minerals. Ideal climatic conditions ensure round the year availability of broad range of fruit and vegetables in large quantities. The production of fruits and vegetables was 97.00 MT and 179.60 MT during the 2017-2018 in India

Maturity Standards and Harvesting Indices

Harvesting : Harvesting is detaching a commodity from the point of its origin. This point of origin may be an above ground plant part i.e. shoot eg. apple, tomato etc. or an underground plant part eg potato, carrot, etc. or in water i.e. harvesting of fish from a pond (not to be covered in this book).

Abstract

India has become not only self sufficient in food grains but has also emerged as net exporter of wheat and rice. Acute famines in India have practically been eliminated, thanks to increased food availability at the national level, improved early warning systems and expanding infrastructure for more rapid transport of food grains and other products to needy areas. However, the existing post management system, strategies and policies don’t seem to match new challenges. Despite government intervention in pricing and procurement of food grains, primarily wheat and paddy, India continues to suffer heavily on account of losses and wastages incurred during the post harvest stages, which are more manmade than natural. Some losses have already occurred before the arrival of food grains in the regulated and wholesale markets and continue till food grains reach their destination. What contribute to continuing losses and wastages are improper post harvest handling, government policies and their implementation, which even stifle growth and modernisation of grain markets and processors.

Introduction

Food grains have been the key component of the human diet for thousands of years and have played a vital role in framing human civilization. Rice, wheat, and maize, and to a lesser extent, coarse grains are major staples, crucial to the daily endurance of billions of people around the world. Cereal grains are consumed by more than 50% of world population to meet daily calorie requirements. Most grains undergo a milling process that ideally removes the outer bran (pericarp) and germ layers; catering to consumer market requirements. To a farmer, yield is the most prominent aspect. As the grain moves along the supply chain, and as the product reaches the market, quality becomes the key determinant of its sale-ability and economic value. Grain quality is defined by a range of physical and compositional properties where threshold necessities are set according to end consumer use requirements. Most industries and consumer markets have become habituated over the years to demand grain with specific attributes. Where consumers are close to the source of grain production (e.g. in local markets), their own preferences and the laws of supply and demand control the grain quality. However, where grain is traded over large distances, particularly internationally, consumers almost have no direct influence on quality, requiring regulatory standards to be established and imposed to protect consumer rights. Therefore in the grain supply chain, all points have effects with respect to grain quality.

19.1. Introduction

Quality is a measure of the degree of excellence or degree of acceptability by the consumer. It is also defined as the combination of attributes or characteristics of the products that has significance in determining the degree of acceptability of the product to a user. Industry defines quality as the measure of purity, strength, flavour, colour, size, maturity, workmanship or any other distinctive attribute or characteristics of the product. According to USDA Marketing Workshop Report (1951) quality is the combination of attributes or characteristics of a product that have significance in determining the degree of acceptability of the product to the user . The quality standards of fresh and processed fruit or vegetable products vary with their intended use. For marketing purposes; size, attractiveness, maturity, organoleptic quality and freedom from defects are to be kept in mind. While for processing, physico chemical attributes of raw material such as presence of soluble solids, development of uniform colour, flavour, juiciness, uniform maturity, tenderness in some vegetables etc are taken into consideration. During processing of fruit or vegetables into value added products; colour, flavour and texture etc also become important.

1. Introduction
Quality makes the product what it is. Quality is how well a product or service satisfies the needs of the customer. Quality can be interpreted in several ways, such as conformance to the standards, meeting customers’ preference/ satisfaction for desired quality attributes, degree of excellence, zero-defect products, etc.
The quality standard of fresh and processed fruit or vegetable products varies with their intended use. For marketing purposes, size, attractiveness, maturity, organoleptic quality and freedom from defects are to be kept in mind in fresh and processed fruit or vegetable products. During the processing of fruit or vegetables into value-added products, colour, flavour and texture also become important. Therefore, Quality is defined in different ways, such as:
i. Quality is a measure of the degree of excellence or degree of acceptability by the consumer.
ii. Quality is also defined as the combination of attributes or characteristics of the products that have significance in determining the degree of acceptability of the product to a user.

Quality is an increasingly important factor in the production and marketing of biological products. Consumers are becoming more discerning as their affluence increases, and would be suppliers of products must meet these demands if they are to maintain or increase market share. The term ‘quality’ is one of the most defined terms in use in food industry today. Quality may be defined as ‘The totality of features and characteristics of a product that bear on its ability to satisfy a given need’. The first part, ‘The totality of features and characteristics of a product…..’ concerns objective factors related to the product.  The second part, ‘…… to satisfy a given need’, concerns subjective factors related to user or consumer of goods.

Introduction

It is necessary to ascertain the quality of irrigation water so as to gauge the possible effects of this water on the soil. The irrigation water often results in water logging, salinity and alkalinity problems. It is therefore very important to know its quality. Following are the basic criteria or characteristics on which irrigation water quality is judged.

1. Presence of total soluble salts in irrigation water.
2. Proportion of carbonates and bicarbonates in relation to calcium and magnesium in irrigation water.
3. Proportion of sodium in relation to other cations in irrigation water.
4. Concentration of specific ions in irrigation water.

Several parameters are employed to judge the quality of irrigation waters No parameter in complete in judging the quality of irrigation water. Further the quality of water should be judged by considering the crop and soil factors. Any judgment without considering the above factors may not be useful. Researchers devised many parameters by following above said criteria. Some of the commonly adopted parameters used to judge the quality of irrigation water are:

Whatever may be the source of irrigation water viz., river, canal, tank, open well or tube well, some soluble salts are always dissolved in it. The main soluble constituent in water are Ca, Mg, Na and K as cations and chloride, sulphate bicarbonate and carbonate as anions. However ions of other elements such as lithium, silicon, bromine, iodine, copper, cobalt, fluorine, boron, titanium, vanadium, barium, arsenic, antimony, beryllium, chromium, manganese, lead, selenium phosphate and organic matter are also present. Among the soluble constituents, calcium, sodium, sulphate, bicarbonate and boron are important in determining the quality of irrigation water and its suitability for irrigation purposes. However other factors such as soil texture, permeability, drainage, type of crop etc., are equally important in determining the suitability of irrigation water.

The following are the most common problems that result from using poor quality water.

The quality of irrigation water has a direct influence on soil properties, crop growth and the long-term sustainability of irrigated agriculture. Water containing excessive salts or undesirable proportions of specific ions can create salinity, sodicity and other soil-related problems. This chapter presents the major criteria used for evaluating irrigation water quality. Salinity hazard is considered as an important indicator of the potential for salt accumulation in the soil and consequent restrictions on plant water uptake. Sodium hazard is examined because excessive sodium can adversely affect soil structure and permeability. The chapter also considers the salt index as a measure relevant to the evaluation of irrigation water. Bicarbonate hazard is discussed in relation to the chemical behaviour of irrigation water and its potential effects on soil conditions. Magnesium hazard is another important consideration in assessing the suitability of water for irrigation. By bringing these criteria together, the chapter provides a framework for evaluating irrigation water before application. Proper assessment of water quality is essential for selecting appropriate management practices and preventing long-term degradation of irrigated soils.

Introduction
Water is one of the most vital natural resources for sustaining life on Earth. However, its availability is not uniform across the planet, and the growing demand for freshwater in the face of climate change, population growth, and industrial development has raised serious concerns about the future of water resources. In 2024, the global water landscape presents both challenges and opportunities, shaped by shifting environmental patterns, technological advances, and policy responses to water scarcity. Water resources refer to the natural sources of water that can be utilized for various purposes, including water supply. Approximately 97% of the Earth’s water is saline, found primarily in oceans, while only about 2.5% is fresh water, but only a small portion of this is accessible. The majority of freshwater is locked in glaciers, ice caps, and deep underground aquifers. Less than 1% of Earth’s freshwater are readily available in rivers, lakes, and accessible groundwater for human use. Of this small fraction, nearly two-thirds is locked in glaciers and polar ice caps. The remaining unfrozen fresh water exists predominantly as groundwater, with only a small percentage available as surface water in rivers, lakes, and atmospheric moisture. The primary natural sources of freshwater include surface water, underflow in riverbeds, groundwater, and frozen water in glaciers. In addition to these, artificial sources such as treated wastewater (reclaimed water) and desalinated seawater are increasingly being used to supplement the global freshwater supply, particularly in regions facing water scarcity. As agriculture accounts for approximately 70% of global freshwater withdrawals, the management and quality of irrigation water are vital for sustaining food production and maintaining the health of ecosystems. Water is essential not only for basic plant functions, such as photosynthesis and nutrient absorption, but also for controlling temperature and supporting soil structure. In regions where rainfall is insufficient or irregular, irrigation provides a reliable source of water to meet the needs of crops throughout their growth cycle.

Water used for irrigation contain some salts, but quantities and kinds vary greatly depending on the source of water. Since sodic status of soils can be greatly influenced by salts in irrigation waters, successful irrigation practices require the evaluation system to judge irrigation water quality and methods employed. The actual damage done by salt to plants or soils depends on the concentration in soil solution rather than the quality of irrigation water applied. Thus, the use of some water source for irrigation might lead to severe salt problem in soils where drainage is restricted.

Criteria for evaluation of irrigation water

Various criteria considered in evaluating the quality of irrigation water are:

1. Salinity hazard

The most satisfactory method for rating the salt content of irrigation water involves measuring electrical conductivity. Various conductivity limits have been proposed to indicate the degree of salinity problems that might be anticipated with use of irrigation water on crops. There are four classes of salinity hazard such as C₁, C₂, C₃, and C₄.

Seed in agriculture recognized as one of the most vital and crucial input in agriculture ever since the human kind has started tilling the land to produce the food for his existences. Seed technologist defined seed as matured fertilized ovule consisting of an intact embryo, endosperm and or cotyledon with protective covering (seed coat). A quality hybrid maize seed production system ensures design of the production technology which enables to maintain the healthy embryo, endosperm and /or cotyledon with protective covering. In fact the search of quality seed had acted as a major force to evolve the science of plant breeding. Ever since the farmers understood the importance of seed, they started trading the quality seed within community and now between geographies. Self-pollinated crops possess the natural mechanisms to maintain the intactness of genetic constitution of a seed during multiplication as there is very minimal chance of natural crossings. On the contrary, cross pollinated crops like maize requires special techniques in seed multiplication to maintain the genetic constitution of a F₁ hybrid. Hybrid Maize seed production techniques are well defined and are used by public and private sectors to produce the required hybrid seed in India. In this chapter, I will be highlighting the process, potential agro-climatic zones, hybrid maize seed production capacity and its future perspective in India. In addition, it also reviews the current system and possible strategic move in order to support the maize seed production system and steps required to meet future demand.

Quality standards are essential in the highly competitive global textile and apparel industry, where products must satisfy increasingly demanding consumer expectations and international trade requirements. They establish consistent benchmarks for regulatory compliance, product safety, performance and ethical production. Standards also strengthen trust among manufacturers, brands, retailers and consumers while facilitating trade between countries. They are authoritative documents containing requirements, specifications, guidelines or characteristics that ensure materials, products, processes and services remain fit for their intended purposes. By providing common terminology, procedures and expectations, quality standards enable stakeholders throughout the supply chain to communicate effectively, evaluate products objectively and maintain consistent levels of performance and conformity.

Food is a major determinant of health, nutritional status and productivity of the population. It is, therefore, essential that the food we consume is wholesome and safe. Unsafe food can lead to a large number of food-borne diseases. It is necessary that the food available is safe, hygienic, wholesome and its quality must be assured. Quality of foods can be defined as the ‘composite’ of those ‘characteristics’ that differentiate individuals units of a product and have significance in determining the degree of acceptability of that unit by the buyer. In general, the quality control is the maintenance of quality at levels and tolerance acceptable to the buyer, minimizing the cost for the vender. But, from the scientific angle the overall quality refer to technical, physical, chemical, microbiological, nutritional and sensory parameters to achieve the wholesome food. These quality factors depend on the specific attributes such as sensory properties, based on flavour, colour, aroma, taste, texture, quantitative properties viz. percentage of sugar, protein, fibre etc and hidden attributes like peroxide, free fatty acids, enzymes etc. Though quality attributes are many, not all need to be considered for a particular product. It is imported to determine how far relatively the factor is in relation to the total quality of the product.

Hence, the quality attributes of a particular is based on the composition of the product, expected deteriorate reaction, packaging used, shelf required and the type of the consumer i.e., deployed in terrain conditions or in peaceful situation. With the ultimate goal of protecting the consumer, quality standardization systems have come into force for regulating the gamut of operations in food manufacture. In a broader sense, food laws and Regulation cover the related acts affecting the marketing, production, labeling, food additives used, dietary supplements, enforcement of General Manufacturing Practice (GMP), Hazard analysis and critical Control Point (HACCP), federal laws and regulations, factory inspections and important-export inspections.

The quality of medicinal plants is paramount in respect of its therapeutic value. The therapeutic value of a plant solely depends on its genuineness in respect of its identity and optimum quantity of therapeutically active phyto-constituents. The medicinal plants are resourced from wild and cultivated sources. The major sources of medicinal plants are wild sources viz. forest areas, open land, non-cultivated sources etc. The medicinal plants collected from wild sources remain questionable for their quality especially when they have been procured from trade channels owing to fair chances of adulteration, substitution and inappropriate storage condition which lead to deterioration in quality. All the medicinal plants which are available in dried form in the trade are termed as crude drugs and are always subject to quality check in a laboratory on the basis of pharmacognostical, physico-chemical, phyto-chemical, microbiological and other analytical specifications. These specifications are available in pharmacopoeial monographs under regulatory frame work.  The pharmacopoeial standards are experimentally established and are also approved standards incorporated in a pharmacopoeia. A pharmacopoeia is a book of standards applicable to drug substance and their dosage forms of common usage in a country. Pharmacopoeia is prepared by recognized authority appointed by the Government of a particular country. It is an essential requirement of a regulatory framework in the sphere of Drugs and Cosmetics Act 1940 and Rules there under (Anonymous 1940). Pharmacopoeial standards are experimentally established and approved standards.
