Worldwide, agriculture is the foundation of early human civilization. Humans transitioned from hunting and gathering to farming when they settled near rivers. As a consistent source of food, agriculture aided in human evolution. From then on, the economy has been sustained by agriculture. Among other things, illnesses and natural disasters frequently have an impact on agriculture. Such a state required advisory. This explains the existence of the agricultural extension domain. A social innovation, agricultural extension has been copied, altered, and developed over the years.

Ice cream has evolved from simple frozen preparations into a sophisticated food industry combining dairy science, food chemistry, refrigeration, microbiology, processing technology, packaging, and cold-chain management. This chapter introduces the historical development of ice cream and explains its transformation from a luxury product into a widely consumed frozen food. It examines the characteristics of the industry, major categories of ice cream and related frozen products, flavour classifications, composition, and quality characteristics. The chapter also presents the basic manufacturing process, important quality-control parameters, common manufacturing challenges, and emerging industry trends, providing a foundation for understanding ice cream as both a technical product and a commercial business.

It is supposed that man was evolved on earth about 15 lakh years ago. This man started to move by standing erect on his feet and called Homo erectus L. Later the modern man was evolved called Homo sapiens L. (Sapiens means learning habit) due to his continuous learning habit. It is difficult to trace the exact period of beginning of agriculture. Archeological evidences indicated that, Agriculture started about 50,000 years ago.

Hunting was the primary source of food in olden days and was prevailed for long time. They obtained his food through domestication of some animals like dogs, horse, cow, buffalo etc. They live in the periphery of the forest and migrate from one place to another in search of food. It was not comfortable and they started enjoying by settling at one place near the river and started agricultural system.

Communication is a key to understand things between two people. Today’s communication is entirely different from pre-historic era and has taken many evolution throughout the years. Before alphabets, signs, symbols, letters and telephone evolved, communication was restricted to interpersonal interaction (i.e.) from one person to another in the form of gestures. It is in other terms called non-verbal communication. Today, communicating between two or more people has become too easy that one can communicate with more than 10 members at a time which is in technical means called conferencing.

The growth of internet has paved way for innumerable means of communica- tion. In other words it can be told as, communication is re-defined by technol- ogy. Texts, email, tweets, tele and video conferencing have widely saved much time of people and made them recipients of today’s fast moving world.

Microorganisms (or microbes) are organisms too small to be seen with the naked eye. The science of microbiology is the study of microorganisms, their properties, classification, growth requirements, method of reproduction and distribution in nature. These organisms range in size from tiny viruses to larger bacteria, protozoa, algae, fungi and some of the microscopic worms (helminthes). They are present everywhere in our environment, in our homes, on our bodies, on the things we touch and on the food we eat. They are important for human survival on Earth, playing an essential role in many processes that maintain life. In nature, microorganisms carry out a number of important functions.

1.They are responsible for the decomposition of organic matter.

2.Recycling of nutrients that help to maintain the balance of chemicals in the soil.

3.Special nitrogen-fixing bacteria live symbiotically with certain plants, absorbing nitrogen from the air and converting it into compounds which can be used by the plant for growth.

4.Some algae are capable of photosynthesis, using energy from the sun to convert carbon dioxide in air into carbohydrate.

5.Marine microorganisms form the basis of the food chain in lakes, rivers and oceans.

6.Certain microorganisms are used in the manufacture of food.

7.Pharmaceuticals and drugs.

8.Industrial processes.

9.A valuable tool for scientific research.

10.Use in laboratory experiments to understanding metabolic pathways and in the discovery of the genetic code.

Bakery Industry

Baked goods have been around for thousands of years. The art of baking was developed early during the Roman Empire. It was a highly famous art as Roman citizens loved baked goods and demanded for them frequently for important occasions such as feasts and weddings etc. Due to the fame and desire that the art of baking received, around 300 BC, baking was introduced as an occupation and respectable profession for Romans. The bakers began to prepare bread at home in an oven, using mills to grind grain into the flour for their breads. The oncoming demand for baked goods vigorously continued and the first bakers’ guild was established in 168 BC in Rome. This drastic appeal for baked goods promoted baking all throughout Europe and expanded into the eastern parts of Asia. Bakers started baking breads and goods at home and selling them out on the streets.

This trend became common and soon, baked products were getting sold in streets of Rome, Germany, London and many more. This resulted in a system of delivering the goods to households, as the demand for baked breads and goods significantly increased. This provoked the bakers to establish a place where people could purchase baked goods for themselves. Therefore, in Paris, the first open-air bakery of baked goods was developed and since then, bakeries became a common place to purchase delicious goods and get together around the world. By the colonial era, bakeries were commonly viewed as places to gather and socialize.^[2] World War II directly affected bread industries in the UK. Baking schools closed during this time so when the war did eventually end there was an absence of skilled bakers. This resulted in new methods being developed to satisfy the world’s desire for bread. Methods like: adding chemicals to dough, premixes and specialized machinery. Unfortunately these old methods of baking were almost completely eradicated when these new methods were introduced and became industrialized. The old methods were seen as unnecessary and financially unsound, during this period there were not many traditional bakeries left.

Bakery is a traditional activity and occupies an important place in food processing industry. The bakery manufacturers in India can be differentiated into the three broad segments of bread, biscuits and cake. About 1.3 million tonnes of the bakery products industry in India is in the organized sector out of 3 millions tonnes, while the balance comprises of unorganized, small-scale local manufacturers. Though, there are sufficient automatic and semi-automatic bread as well as biscuit manufacturing units in India but there are still number of people prefer fresh bread and other products from the local bakery. After entry of Pizza and Burgers’ MNCs in the country, people are changing their tastes also. Today, they are not restricted to bread, cake and biscuits but to other bakery products also. The consumers are increasingly going for newer options with respect to bakery products. With the ventures of few Companies like Britannia, Biskfarm, and Morish etc. competition has increased. Also, the Indian market is witnessing the proliferation of bakery cafe chains in the form of Baristacafe, coffee day, Café Coffee & Monginis etc.

Armed with better technology, know-how and novel ideas, these foreign companies have made rapid inroads into the lucrative market within a very short span of time. Though the demand for bakery products in India has always been on the rise, there is clearly a lack of awareness and the will to break new ground, which has helped global players to gain brownie points while exploring the market in India. The unorganized sector accounts for about half of the total biscuit production estimated at 1.5 million tonnes. It also accounts for 85 per cent of the total bread production and around 90 per cent of the other bakery products estimated at 0.6 million tonnes. The last includes pastries, cakes, buns, rusks and others.

Introduction

Food and nutrition security is the basic requirement of human development. Among the ten global burden of diseases, six are connected with diet related factors. Food and nutrition security is also closely related to other factors like socio economic status, geography and demography. Asia, Latin America and Africa hosts world’s most of the undernourished population. Among these regions South Asia is considered as one of the hotspots of malnutrition, in which India is the major contributor. Fifty seven percent of population cannot afford healthy diet in South Asia.

Over the centuries of remarkable economic growth in India concomitant reduction in under nutrition has not been witnessed and this dilemma is called Indian enigma (Gillespie et al 2012; Sengupta 2019). In India among the different socio economic categories, undernutrition has highly been manifested among SC and STs (Gillespie et al 2012; NNMB 2009).The reasons of food and nutrition insecurity are directly linked to remoteness, dire poverty and dysfunctional food security programmes (Khera 2011; UNICEF 2014). Poor and landless among them are mostly falling prey to chronic food insecurity. Coupled with reduction in locally available dietary inputs, rising food expenditure also compel poor to cut back the quantity and resort to low priced calorie dense food (Smyth & Sweetman; 2010). Therefore, poor people’s diet assume to fraught with starch, which leads to nutritional imbalances and resulting in to various lifestyle diseases like diabetics among them. This situation necessitates the need of local, sustainable household food production through home nutrition gardens. Many studies testify the impact of household level food crop cultivation in addressing malnutrition. Kuhnlein & Raceveur 1996; Pimbert 2009; Vira et al 2015 argues inadequate diets are associated with the “delocalization of food supply” and disruption in existed food systems. Therefore, in general literatures on agriculture and nutrition elicits the positive correlation between cultivating food crops and nutrition security (Gillespie et al 2012; Hossain et al 2016; Viswanathan et al 2015). In this context, home nutrition garden programmeassumes greater significance in countering malnutrition among Paniyan community in Western Ghats region of Wayanad district of Kerala.

The number of hormones secreted by the body exhibits control over the physiological regulation of glucose sugar level (homeostasis) in the manner needed by the body. Depending upon the situation, hormones may increase or decrease the level of glucose sugar present in the blood or tissues. The glucose is oxidized to yield energy, carbon dioxide, and water.
Glucose, more than the body’s needs, is stored or converted mainly to glycogen and, to some extent, protein and fat. If glucose is less than the need of the body, its denovo synthesis takes place from amino acids or fatty acids, or is formed from the breakdown of stored glycogen. Various hormones are secreted by multiple endocrine glands to control the blood glucose level. If it fails, it leads to hypoglycemia or hyperglycemia conditions. Gluconeogenesis is not developed at birth in the case of a baby pig. Therefore, hypoglycemia in baby pigs is observed within 2 days of age if starved, leading to hypoglycemia, weakness, confusion, and death.
15.1 The Hormones Involved in Homeostatic Regulation of Blood
Glucose Level
The hormones influencing carbohydrate metabolism are explained below:

Hormones are a group of biochemical messengers that assist in transmitting signals from one part of an organism to another. The term “hormone” was first coined by Ernest Starling in 1905 after the discovery of secretin, a chemical produced in the small intestine that regulates pancreatic secretions. In 1937 Went and Thimann defined hormones as “a substance which, produced in any one part of an organism, is transferred to another part and there influences a specific physiological process”. Since then hormones are also known as chemical messengers. These intercellular messengers are produced by specialized cells of endocrine glands, generally called effectors and released into the bloodstream thereby assisting in the regulation of physiological processes in target cells. Hormones assist in the regulation of a plethora of cell functions such as maintaining homeostasis, metabolism of biomolecules, growth, and reproductive function, and controlling blood pressure and glucose levels that are essential in orchestrating an intricate body- balance. The pituitary, thyroid, pancreas, adrenal, parathyroid, and gonads (testis and ovary in males and females respectively) produce hormones. Apart from these endocrine glands, few other organs such as the kidney, heart, and liver are also involved in hormone production. The pituitary gland

Introduction

Hormones may be defined as specific chemical molecules produced in certain specific organs called specialized cells or endocrine glands. They are delivered into the blood stream or some other body fluid in minute amounts by the circulatory system of the body and their they exerts a physiological effect at a site of action remote from its origin, regulating numerous biological activities including growth, development, reproduction, water & electrolyte balance, storage & usage of energy etc.

13.1 Introduction

Hospitality industry is the second largest industry in the world. It is well diversified and can be chosen as per the interest. Hospitality management involves planning, organizing, directing and controlling human and other resources within the different segments of hospitality industry i.e. lodging, restaurant, travel and tourism, institutional management, recreational management, meeting and convention planning industries. Although, these all are separate but related segments of the hospitality industry and are interrelated to provide good and efficient services to the guests and users. Hospitality industry provides services which are need oriented and differ in various parts of the world as per regions and the traditional styles.

The first building created specifically for hotel was ‘City Hotel’ with 73 rooms at 115 Broadway, New York in 1794. Pallonjee Pestonjee established the very first western-style hotel in India, “The Bristol Hotel” in Mumbai in 1840. According to the report of the department of Tourism, Government of India, at the end of the year 2004, there were 167 Five star hotels with approx. 28,900 rooms, whereas 126 Four star hotels, with 8,831 rooms [2]. To expedite the ongoing process of classification/re-classification of functioning hotels in one to three star categories, five Regional Committees have also been set up in Delhi, Mumbai, Kolkata, Guwahati and Chennai to conduct inspection [3].

Appliances which help or assist in doing household work as cooking, cleaning and food preservation are known as equipments. A equipment also referred to as a domestic appliance or an electric appliance or a household appliance.

Corporate Social Responsibility (CSR) is generally a policy to assess its impact on society and estimate its societal responsibilities. The CSR plan of any organization ensures that it complies with government norms, their investments in respect of growth, development of weaker sections and the environment. CSR’s primary requisite should be sustainable, involving interventions that an organization can justify without negatively affecting its profit goals.

Climate change referred as, a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods (IPCC, 2001). In other words, it is any long term conspicuous deviation from usual prevailing climate bringing variations in normal temperature, rainfall, atmospheric circulation with abnormal expression in extreme climate such as floods, droughts, extreme temperature etc.

Identify and Describe Program You Want to Evaluate

The first step in conducting a program evaluation is to clarify why we are doing it, what we want to achieve, and what we will focus on. This will help us to define the evaluation questions, criteria, indicators and methods that will guide our data collection and analysis.

What is Program Evaluation?

Ten Steps in programme evaluation
i. Identify and describe programme you want to evaluate: The first step of the evaluation process is to identify the object or programme of evaluation. For this purpose, a short written description of the object or programme to be evaluated must be drafted. This description must be formulated in a way that is also comprehensible to outsiders. Relevant items to be included in this description are, for example, the name of the object or programme of evaluation, the expert responsible for it, the employees taking part in it, the goals, scientific references, the contents or topics, the elements, methods, scope, available resources, key figures, past developments, etc.
ii. Identify the phase of the programme
• Design
• Start-up
• Ongoing
• Wrap-up
• Follow-up

Once you have embarked upon the idea of doing (any) business, your concentration should be focused on doing things that should be relevant to maximizing returns and minimizing risks. Looking upon why businesses fail, one can find that it is usually because entrepreneurs are ill equipped to identify real business opportunities and take advantage of them, or they don’t anticipate and adapt critical changes or they fail to recognize or minimize real threats to business. Successful entrepreneurs are found to intensively pursue the path of planning by preparing business plans, for having foresight of critical incidents that would affect business and possible ways of action.

1.1. INTRODUCTION

Researchers interested in taking up research have initial difficultes in picking up a problem worth for investigation. At time they waste considérable amount of time in just thinking about the pros and cons of problems suggested by some ones or identified by himself/herself. It is basically due to misunderstanding about "what is research". Usual notion about research is that it must resuit in something spectacular or it must come up with a new discovery or theory. It must be pointed out that a study which brings forward new facts, or which demolishes or establishes a hypothesis or a theory or principal already in vogue, or which puts a variety of information in to order or system, or which prepares ground for further research is as valid as one which ends with a new discovery. The best research problem for researcher is one which arises from the researcher's own curiosity. The only thing is that researcher must know the tools which can handle the problems he proposed to take up. Before choosing for a problem for research one should as question to himself: is this problem really of interest to me?; Is it significant in the sense that it extends the frontiers of knowledge or fills an important gap in knowledge?; Can I handle this problem within the constraints of resources of money, time etc?; has this problem not been investigated by someone else? A good research proposai describes situation of problem, problem area, justification, methodology adopted for data collection, analysis, expected results and institution/ organisation that may use the outcome.
