Introduction
The term canning refers to a process in which the food is heated in hermetically sealed containers at a specific temperature for a specific time to eliminate microbial pathogens that endanger public health; and microorganisms & enzymes that deteriorate food during storage. The credit for the invention of canning goes to a French confectioner Francois Nicholas Appert, who was awarded a prize in 1809 by the French government for developing a new method of heat preservation of food in a sealed container and after whose name the process of canning has also been named as Appertization. In 1810 Nicholas Appert published the first book on canning entitled “The Art of Preserving Animal and Vegetable Substances for Many Years.” which is the first known work on canning. The work of Appert consists of packing food in glass bottles, closing them with corks, and heating the container in boiling water for several minutes depending upon the type of the food. Although the developed technique was used to preserve different types of food, the actual reason for the prevention of spoilage was known only after the work of Louis Pasteur (1864) who discovered that food spoilage was caused by microorganisms that were destroyed at elevated temperatures and the technique was known as Pasteurization. This understanding helped to form a scientific basis for establishing and revolutionizing the canning industry. Canning of fruits on a commercial scale was introduced in the USA in 1817 by William Underwood. The old phrase ‘necessity is the mother of invention’ suits well for the development of the canning industry during wars. The Civil War in America and the Great European War of 1914 also gave impetus to the development of a canning industry to meet enormous requirements of food for the fighting forces.

Canning is a process of sealing food stuffs hermatically in containers and sterilizing them by heat for long storage is known as canning.

Principle of Canning

Destruction of spoilage organism within the sealed container by means of heat.

Selection of Fruit and Vegetable

For canning fruit should be ripe but firm and uniformity mature and vegetables except tomato should be tender.

Grading

Selected fruit and vegetable are graded according to size and colour to obtain uniform quality. This is done by hand or machines such as screw grader and roller grader.

Capacity building represents a fundamental process through which individuals, organizations, and societies develop, strengthen, and maintain their abilities to perform functions, solve problems, and achieve objectives effectively over time. This multidimensional concept encompasses the enhancement of knowledge, skills, systems, and institutional arrangements that enable entities to fulfill their mandates and respond to emerging challenges. The United Nations Development Programme defines capacity building as the process by which individuals, organizations, and societies obtain, strengthen, and maintain the capabilities to set and achieve their own development objectives. This definition emphasizes the dynamic and sustainable nature of capacity building, highlighting its role not merely as a one-time intervention but as an ongoing process of organizational and individual growth. The conceptual foundation of capacity building rests on the understanding that sustainable development and organizational effectiveness require more than temporary fixes or external assistance. True capacity building involves creating endogenous capabilities that can be sustained and enhanced over time without continuous external support. This approach

Training

Training represents activities that teach employees how to better perform their jobs. Training is a powerful tool in the hands of development professional to catalyze human resources. Training is a process of acquiring specific skills to perform ajob better.

Training as the act of increasing the skills of an employee for doing a particular job

Training always aim at lasting improvement on the job. It is primarily organized not for learning more but to behave differently in own endeavors

“Activities which develop individual knowledge, talents, skills, and behaviour and improve institutional structures and processes so that the organization may efficiently accomplish its mission and goals in a sustainable manner” it refers as a capacity building. One of the crucial elements of capacity building is training.

Training for Development

Training is becoming an integral component of HRD. It has developed into one of the elements that allows any institution to produce its personnel who are the most productive and qualified.

The livelihoods of millions of rural households in the semi-arid areas depend mainly on natural resources such as soil, rainwater, vegetation, livestock and the like. The major source of livelihood in these areas solely depends on the arrival, distribution and cessation of monsoons, which are erratic and ill distributed. However, management of natural resources like soil and vegetation in a way that these are used to optimally to produce maximum output. This requires new knowledge, better skills and improved management strategies. In this context, building the capacity of the rural households particularly the youth holds key to improving productivity and profitability ot the enterprise. Keeping these in view, the National Agricultural Innovation Project (NAIP) sub project on “Sustainable Rural Livelihoods through Enhanced Farming Systems Productivity and Efficient Support Systems in Rainfed Areas” being implemented by a consortium led by CRIDA has introduced several interventions aimed at involving rural youth right from the beginning of the project.  The project is being implemented in eight backward districts (Adilabad, Anantapur, Kadapa, Khammam, Mahabubngar, Nalgonda, Rangareddy and Warangal) of Andhra Pradesh in selected clusters of villages.

Abstract

The Stree Shakthi Groups (SHGs) were launched in Karnataka during 2000-01 aimed at improving the overall development of rural women in Karnataka. A review of the progress achieved by these illeterate or less educated, hither to continued to be economically dependent with no voice in decision making, is nothing short of a miracle. With an enrollment of one and a half million in 5000 villages, their savings and borrowings run into hundreds of crores and employment opportunities are provided to lakhs of farm women. Apart from agriculture related activities, some of them have also involved in some unconventional, income generating activites. Economic empowerment has emboldened these beneficiaries to not only fight against social evils but also win their battles. Overall, SHGs have transformed the life of rural women treatmendously in a positive direction.

Introduction

Carbohydrates are the most common source of energy for all living cells, which, in presence of light, are formed by the green plants from CO₂ and water during photosynthesis. It canbe said that ‘light’ is theultimatesourceof energyrequired for all livingcells.Glucose,a monosaccharide,plays a centralroleincarbohydrate metabolismin all plants, animals and manymicroorganisms. Glucose is derived from the polysaccharides (starch, glycogen) and non-carbohydrate sources (amino acids, glycerols, etc.) during metabolism and ultimately converted either into carbondioxide and water orotherintermediateproducts.Complete oxidation of glucose to CO₂ and water provides ~2,840 kJ/mol energy. The other monosaccharides such as fructose, galactose, mannose, etc. are also important molecules in carbohydrate metabolism.

1. Carbohydrates are primarily composed of the elements
   1. Carbon, hydrogen and oxygen
   2. Hydrogen, oxygen and carbon
   3. Oxygen, carbon and hydrogen
   4. None of these
2. Carbohydrates have an empirical formula
   1. (CH₂O)_n
   2. (CH₂O)_n+₁
   3. (CH₂O)_n-₁
   4. (CH₂O)_n/₂

Food is composed of three main constituents viz; carbohydrates, proteins and fats and their derivatives. In addition to these constituents, inorganic mineral elements and diverse organic compounds like vitamins, pigments, flavouring compounds, enzymes, and acids are also present. Carbohydrates, proteins, fats and vitamins are organic in nature. The percentage of water is large in certain foods. The variation in structure, texture, colour, flavour and nutritive value is because of the varying proportions and arrangements of these constituents.

Carbohydrates are important in foods as a major source of energy, to impart crucial textural properties, and as dietary fiber which influences physiological processes. Digestible carbohydrates, which are converted into monosaccharides, which are absorbed, provide metabolic energy. Carbohydrates account for more than 70% of the caloric value of the human diet. It is recommended that all persons should limit calories from fat to not more than 30% and that most of the carbohydrate calories should come from starch. Non-digestible polysaccharides (all other than starch) comprise the major portion of dietary fiber.

ABSTRACT

The rapid growth in population has created the need of industrialization and as a result there has been a significant increase in milk production and processing. Milk is a commodity which is consumed by persons of all age groups due to its nutritive value and health promoting attributes. However, the rapid growth in dairy sector has adversely affected the environment by emitting various greenhouse gases and thereby, resulting in global warming. Apart from it, there has been an increased usage of non- renewable resources like natural gas and coal in dairy sector. As a result, a viable balance has to be maintained between milk production and processing, environmental health and the rapidly growing population. This can only be achieved with the application of green or environment friendly technologies in all the stages of milk production and processing. This chapter will mainly deal with the various sources of greenhouse gases from dairy sector and on application of life cycle assessment and carbon foot printing for computing the impact of greenhouse gases on the environment. Also, this chapter will enclose various green technologies which can be applied in dairy sector to curb the greenhouse gas emissions.

Introduction Nanoscience is a competitive and trending concept in present scientific community, especially in agricultural and allied sciences. The usage of nano-sized materials in food processing sector spreading slowly. With the passage of time and innovation continuation in nanotechnology creating interest to develop miniaturized sensors. Miniaturized sensors have lots of benefits like reducing bulkiness with low power consumption and this eventually reduces the cost. Generally inorganic semiconductors are widely used to develop nano sensors. Generally, sensors are composed of two basic unit which are an identification element and a signal transducer element. Due to its simple structure, high portability and low price, can benefitted against disadvantages of existing system, which are costlier and much more popular. High portability, ease of placement and use make it suitable for onsite use with real-time monitoring. Also, helps in qualitative and quantitative analysis of such substances during analysis of foods which may cause danger and thus inhabit a wider research and development space. For the detection of different unwanted materials or compositions in food, various chemical or biological sensing devices based on different working principles have been developed. The carbon-based nano material can be categories as Ordered Mesoporous Carbon, Carbon Nanotubes, Graphene and Its derivatives, and Carbon Dots.

1. INTRODUCTION

There are many countries surrounded by the waters of the Caribbean Sea. These countries vary widely in size, topography, ethnicity, language spoken, agricultural production systems, main sources of income, income levels and styles of governance, to name a few.

This analysis covers only the countries where English is spoken as the first language. These countries are linked through a grouping of Caribbean Communities, called CARICOM, an organization of 15 Caribbean nations and their dependencies. It starts with Jamaica in the North to Trinidad and Tobago in the South, but also includes Belize in Central America and Guyana and Suriname in South America. Although French speaking Haiti and Dutch speaking Suriname belong to CARICOM, they are not discussed because of the language barrier. The other French speaking islands (Guadeloupe and Martinique) and the Spanish speaking islands (mainly the Dominican Republic, Cuba and Puerto Rico) have different administrations for agricultural development. CARICOM countries stretching from the tip of Florida, USA, in the North to Venezuela in South America. CARICOM includes Belize in Central America and Guyana and Suriname in South America.

Study of Carpentry Hand Tool

Introduction

The process of making the wooden components is called carpentry. Carpentry deals with the mechanical work of making wood components such as making beds, roofs, wardrobes, tables, cases, utensils, floors, etc. It manages the structure work, furniture, cabinet making and so on joinery, i.e., preparation of joints is one of the significant activities in all wood works.

The products produced are used in making furniture, musical instruments, and building constructions like doors, windows, desks, chairs, cupboards, etc., of a place utilizing a specific kind of wood with the help of tools known as carpentry tools. Different wooden pieces are connected to make a useful product. Wood is used to make furniture, boxes, doors, windows, industrial floors, stairs, pencils etc.

In order to portray the conditions of the migrated rural youth in cities, who otherwise would have been practicing agriculture, a few case studies were conducted to know more about the migrated rural youth, their family background, reasons for migrating, satisfaction after migration, type of support given to the family at the villages, assets created at their village and in the cities, types of problems faced, opinion about the environment, and willingness to go back to their villages for continuing farming. The sample included migrated persons engaged in different jobs in Bangalore city as Hotel workers, Construction Workers, Auto Drivers / Taxi drivers, Security Guards, Garment workers and Vegetable/Fruit Vendors. From each category, five respondents were interviewed by using a simple questionnaire. Following are the case studies.

I. Case Studies on Migrated Rural Youth Working as Building Construction Workers

1. Case of Sri Krishnappa : Muttanna, V.L. Madhuprasad and D. Nanjappa

Sri. Krishnappa S/o Saranappa, aged 30 years from Surapur taluk, Yadagiri district had migrated to Bangalore as a construction labourer. He had completed his primary education and got married at an early age. He has two sons and  two daughters.  After marriage, he continued to live in a pucca house along with his parents, one brother and two sisters.  The family has two acres of dry land, and  farming is main occupation. Desire to earn more money by him and non  co-operation among members of his family are the reasons for Sri Krishnappa’s migration.

1. Success Story of Rural Youth in Dairying
 
M.S. Nataraju, P. Sunil Kumar and R. Shashidhar

There is a proverb in Kannada that “Koti Vidyeginthaloo Meti Vidyee Yee Melu” means - among all the professions for livelihood on this earth agriculture is the best profession for better livelihood.  This proverb suits Sri. Vasudeva Indraje, resident of Yenmoor village in Sulliya Taluk of Dakshina Kannada Dist. in Karnataka State. Sri. Vasudeva Indraje is a role model for today’s youth, who are neglecting agriculture and migrating to cities with an illusion of making a quick buck.  Hailing from an agricultural family his moorings was in agriculture and allied activities.  After passing out from SSLC he did not seek to continue the studies but showed interest in pursuing some small business.  Along with his younger brother he started a cold drink house in Balila and made good profit from it.  When it appeared that the business was seeing a downward trend he came out of the business and invested the money in farming land.

Sri. Vasudev along with his friend visited RUDSETI, Ujire and enquired about the training programmes. After going through his interests Director suggested him to apply for Dairy and Vermicompost training programme.  Later, he was selected and undergone Dairy and Vermicompost training programme in the year 2007.  During his training programme along with the technical inputs regarding the Dairy management he also learnt about different soft skills like how to develop entrepreneurship competencies? How to develop Self Confidence? How to avail Institutional Credit? etc.

Planning Research and Action Institute, Lucknow (1960) found that lack of initial capital considerably hindered the growth of Animal Husbandry Projects in Youth Clubs. It was also revealed that involvement of non-official agencies and training of youth organizers were very important for strengthening youth clubs.
Singh and Prasad (1963) identified that following deficiencies in the working of youth clubs.
    1.    Inadequate knowledge of youth club work on the part of members as well as on leaders
    2.    Non-availability of literature on youth clubs
    3.    Lack of active leadership‘
    4.    Rift between village youth clubs and village panchayat
    5.    Lack of proper guidance and follow up of youth club programme
Behniwal (1964) revealed the following factors as responsible for the successful working of youth clubs.
    1.    Strength of membership in a club 
    2.    Participation in project work
    3.    Participation in games
    4.    Frequency of meetings
    5.    Attendance in tours, rallies and games
    6.    Actual gains received  
Kumar (1965) found that in the successful clubs the youth had clear conception of the importance and objectives of the youth organization.
