Bread is considered as one of the oldest processed foods to be known, traditionally prepared using wheat flour and water and baked on hot stones. The process of bread making involves hydration of protein and formation of gluten network ABSTRACT 70 Bakery and Confectionery Technology upon mixing, the evolution of carbon dioxide owing to the action of yeast on sugars and aeration of the mixture by incorporation of the gas followed by coagulation of the dough upon heating it in the oven. 

The history of cakes traces back to ancient times where Egyptians first practiced advanced baking skills. However, the modern-day cakes are said to have evolved in Europe around mid of 17th century. Today cake products and its derivatives are widely found all around the world. Cakes are sweet baked products rich in sugar, fat and egg with a tender bite and a pleasant flavour. They are basically protein foams, stabilized by gelatinized starch. Quality of cake depends on number of factors like selection of ingredients, balancing of recipe, optimum mixing and baking procedures. Good quality cakes are characterized by large volume, uniform crumb with fine cells and pore size.

Confectionery is an vital food item of great acceptance among wide range of population. It has been relished as a major food delicacy from ancient times. The term confectionery is describes a spectrum of sweet goods and takes on different meaning depending on the country in which it is used, for example in the United Kingdom the term applies to any sweet product including cakes. In the United States confectionery is candy and includes sugar confectionery and chocolate confectionery.

In the Modern era of globalisation, a wide variety of miscellaneous bakery products are available. It is hard to acknowledge all of them in this chapter due to the unlimited specialities of bakers across the world. The writing here in this chapter is limited to formulation & technology used for the production of buns, pizza base, chapatti, wafers, pretzels, crackers and muffins individually.

Technology Promotion
The activity of promoting the transfer of technology by creating opportunities, advertising and organizing technology events.
Promotion is a marketing tool, used as a strategy to communicate between the sellers and buyers. Through this, the seller tries to influence and convince the buyers to buy their products or services. It assists in spreading the word about the product or services or company to the people. The company uses this process to improve its public image. This technique of marketing creates an interest in the mindset of the customers and can also retain them as a loyal customer.
Promotion is a fundamental component of the marketing mix, which has 4 Ps:
1. Product (Warranty, features, variety, quality, design, packaging, brand name)
2. Price (List price, discounts, payment terms, credit)
3. Place (channels, coverage, Types of promotion locations, transportation, inventory)
4. Promotion (advertising, self-marketing/personal, sales promotion, public relations, direct marketing, trade shows, events).

Introduction

Sugarcane based production system has to go a long way to turn hightech because of the existing technological gap in the irrigated agroecosystem. This has been realized more in the recent studies undertaken by social scientists. All the crops associated with the sugarcane based production need varietal introduction as well as the adoption of relevant crop management practices. Since the possibility of increasing area under sugarcane is remote in view of emerging low input high value crops, the projected target of 420 million tonnes by 2020 AD has to be achieved by enhancing the cane productivity and sugar recovery concurrently. The full exploitation of the existing improved sugarcane production technologies and development of a package of agro-techniques in the changing scenario of sugarcane based production system suiting to the socio-economic conditions of the farmers is as such the only master key to unlock the yield potential of sugarcane.

Hypothesis testing is the statistical procedure used in order to accept or reject statistical null hypotheses. One of the major purpose for which we formulate the hypothesis is, to test the statistical significance of the relation, difference or variation etc. among given sample/s at a given point of time or at different time points.

Introduction

Test of pollen viability (extent of pollen viability) is important in pollination experiments to ensure fertility/seed setting. It is also important in monitoring state of pollens during storage in ecological/ taxonomic studies as well as during research on pollen biochemistry, genetics, stigma interactions, and incompatibility studies. Pollen viability refers to the ability of pollen to accomplish post-pollination events to achieve fertilization. Pollen viability test has gained importance particularly in plant breeding and hybrid seed production experiments/ practices. In this chapter, you will be acquainted with the basics of pollen viability test. However, for more professional knowledge on the topic readers are suggested to refer specialized books.

Pollen Viability Test

It is important to know the extent of viability of pollens used in pollination experiment, in finding fertility of a plant of interest, to monitor state of pollen on storage, in ecological/taxonomic studies, as well as in research on biochemistry, genetics, stigma interaction, incompatibility assay, etc. of pollen. Several pollen viability tests have been developed time-to-time. It is recommended to initially use different tests for a given pollen type to find out the most appropriate method that provides reliable result on pollen viability. It is important to note that every procedure requires standardization of protocol according to the sample used. Following different tests are used for assessing pollen viability.

1. In-vitro Pollen Germination Test

It is a simple, speedy, and quantitative test for assessing pollen viability. In this method, a collection/sample of pollen is germinated in vitro and observed under microscope. The percentage of germinating pollens (producing pollen tube) after appropriate treatment and a given period of time is determined. The percentage provides an index of viability of the pollen sample.

Introduction

Seed is a living entity (mature ovule) consisting of a tiny plant in embryonic stage along with the stored food protected by an outer layer known as seed coat. Seed is an important biological input in agriculture, which is economically important for successful crop husbandry. Cotyledons serve as the source of nutrients (proteins, carbohydrates, and oils) that not only nurture the plant at the early developmental (seedling) stages of plant but also the vegetarian (heterotroph) organisms. Being one of the important inputs in agriculture, viability of seed needs to be assessed to know the germination percentage of seeds used to raise a crop. Since viability of seeds may deteriorate on storage depending on the storage conditions. Therefore, often it becomes important to test viability/germinability and vigour of seeds before being used for raising a crop or conducting an experiment. In this chapter, we briefly discuss about the different methods which can be used for testing the viability of seeds.

Seed Viability

Seed viability can be defined as the capability of the seed to germinate and produce a normal seedling within a specified period. In other words, seed viability indicates how many seeds in a lot are alive and could develop into plants under appropriate field conditions. It is very important that most of the stored seeds are capable of germinating when sown in a field. They must possess higher viability at the beginning of storage and maintain it over the storage. A seed with high initial viability survives longer in storage; however, the viability deteriorates slowly at first and then rapidly as the storage prolongs. It is important to know the duration of storage after which a considerable decline in viability occurs under given storage conditions so that to take necessary action to revive the seeds. Excessive deterioration in vianility of seeds may lead to loss of the seed/material/ germplasm.

The growing chemicalization of milk presents a great challenge to the dairy industry. A number of chemical compounds get entry into milk, intentionally or un-intentionally, through their direct or indirect usage for crop, animal; or dairy husbandry practices, as environmental contamination. Several of these contaminants may be naturally present on grazing grass or use as pesticides for green fodder or they may get entry through use of compounded animal feeds. These eventually get excreted into milk as residues and pose problems to food safety. The risk of health hazards arises from veterinary drugs, residual pesticides, heavy metals, detergents and micotoxins etc. It is therefore, become necessary to detect these contaminants in order to make food safe for human consumption.

10.1. Introduction

Decision-making is a fundamental aspect of human life, influencing choices in both personal and professional settings. Every individual, whether consciously or unconsciously, engages in decision-making daily, ranging from simple tasks like selecting a meal to complex strategic planning in organizations. However, decision-making becomes increasingly challenging when multiple conflicting criteria are involved. The presence of numerous factors, each with varying degrees of importance, often creates ambiguity and uncertainty, making it difficult to arrive at the most suitable option. To address these challenges, structured decision-making methodologies have been developed to provide a systematic and logical framework for evaluating alternatives.

One such widely recognized method is the Analytical Hierarchy Process (AHP), introduced by Thomas L. Saaty in the 1970s. AHP was designed to assist decision-makers in breaking down complex problems into a structured and systematic hierarchy. This approach allows for a step-by-step evaluation of different factors, making it easier to analyze their relative importance. By structuring a problem into different levels - such as goal, criteria, sub-criteria, and alternatives - AHP provides clarity in decision-making and enhances consistency in judgments. The method is particularly beneficial when dealing with decisions that involve both tangible and intangible factors, as it allows subjective preferences to be quantified systematically (Saaty, 2008).

Introduction

In the annals of history, the term “Renaissance” evokes images of a time marked by profound cultural, artistic, and scientific rebirth. The Renaissance of the 14th to the 17th century was characterized by an extraordinary surge in creativity and intellectual achievement, which laid the groundwork for the modern world. Today, we find ourselves at the cusp of a new Renaissance—a Digital Renaissance—propelled by the rapid and relentless advancements in technology. This new era, like its historical counterpart, is marked by a transformative shift that is redefining every aspect of human life, from how we work and communicate to how we learn and govern.

This chapter delves into the essence of this transformative era, exploring the fundamental technological innovations reshaping our world and their far-reaching impacts on society. We will examine the pivotal technologies driving the Digital Renaissance, including artificial intelligence, blockchain, the Internet of Things (IoT), and other emerging technologies such as virtual and augmented reality and 5G networks. By understanding these technologies and their applications, we can appreciate how they collectively contribute to a digital transformation that is as revolutionary as the artistic and scientific achievements of the past.

Introduction

Food being the foremost basic need gets the priority in expenditure of people, especially poor class. Access to food demands affordability, which depends upon the twin factors namely, income of the people and prices prevailing in the country. Slower growth in income than prices would undermine the purchasing power, resulting in inadequate access to food and calorie consumption. Foodgrains account for about four-fifth of the calorie intake of the poor and an increase in cereal prices could significantly reduce the calorie intake of the poor, as it is sensitive to cereal prices.

Introduction

It is said that Rome was not built in a day. Similarly, Extension was not master minded by one individual; rather it evolved through hard work of extension professionals around the world over more than a country.

The necessity of a human being is food, for which he must rely on agriculture. The agriculture to achieve its expected growth must depend on several factors which include technology, research and obviously extension. The basic function of agricultural extension is to train, teach and guide farmers. Agricultural extension’s primary role is to mentor, instruct, and train farmers.

Introduction

Agriculture has always been linked with prosperity, man power and the ability to feed and raise human population. In earlier times, humans as man power were deployed on the fields to do all the necessary operations to cultivate the crops, but during the industrial revolution, with development of different farm machines the uses of human labor on the fields were drastically decreased. Further, with advancement of technologies and more availability of computers, Artificial Technology (AI) has been gaining momentum in recent years.

AI has the potential to transform the agricultural sector through cost reduction and increased crop yields, and minimizing environmental impacts. AI can help farmers better manage their land, improve crop quality, and increase their productivity In addition, AI can be used to monitor and analyze the health of crops, livestocks, and soils to identify issues and assist in their resolution. The primary idea of using artificial intelligence in agriculture is due its adaptability, superiority, and cost-viability. The customary techniques that were utilized by the farmers were not adequate enough to satisfy their necessities. (Khan et al. 2022) With the right implementation and technology, AI can be an invaluable tool to help farmers increase their efficiency and profitability. In today’s rapidly evolving world, where the demand for food continues to escalate amidst concerns over environmental sustainability and resource scarcity, Artificial intelligence (AI) has become a transformative force in agriculture, from optimizing crop production and resource management to enhancing decision-making processes. Globally, AI is changing how we approach farming techniques.

ABSTRACT

Economic growth of a country depends upon the skills of its people and the application of knowledge, inherited or acquired by them. Optimum utilization of human resources undoubtedly leads to considerable degree of economic development of a country. There are over one billion youth (aged 15 – 24) in the world today. Eighty five (85) per cent of these youth live in the developing world, where 99 per cent of population growth is occurring. Around 50 per cent of the population in developing countries live in rural areas. Some 61.5 per cent of youth live in Asia. Many youth are unable to reach their potential because of poverty and associated hunger and poor health. Also, education and training is often of poor quality and is irrelevant and inappropriate for the needs of rural youth and of the labour market. So although many youth today are more educated than their parent’s generation, they often do not possess employable skills. Even when good education and training are available and youth have been well trained, obstacles still exist, such as social customs (for example, caste and traditional values), lack of support mechanisms and lack of access to capital. Corruption is also a problem, as are structural impediments (institutional and governmental). Also, because youth numbers are growing faster than the rate of job creation, too few decent employment opportunities are available for the number of youth seeking them. The result is that a large number of youth are unemployed or underemployed. Not only do these youth lack income, they lack a means of gaining respect and a sense of belonging in their communities. Inability to find decent employment means youth often find employment in the informal sector, with poor working conditions and pay. Rural youth will often look to urban areas for employment and move to cities that adversely affect the household farming in India.

Abstract

Indigenous Peoples of northwestern North America have utilized several hundred local plant species, as well as some algae, lichens and fungi, in their traditional diets. Many of these are also used in traditional healing, and some have potentially harmful or poisonous properties that must be taken into account in harvesting and preparation. Other species, known primarily for their medicinal use, also have noted toxicity if used improperly or without constraints. In this study, a total of 375 traditional food and medicine plants, fungi, lichen and algal species, as well as those species reported to be toxic by indigenous knowledge holders, were surveyed across 12 First Nations groups, each with distinct languages, for overlaps across the categories of food, medicine and toxic species. A complex of species use and avoidance emerged, modulated by processing, dosage, and other factors, with significant numbers of food species with reported healing properties, food species also used as medicine, and both food and medicinal species known to be harmful or toxic under some circumstances. Even most of those species considered extremely poisonous have been taken internally as medicines in some way by some groups.
