RURAL DEVELOPMENT

Meaning

The word “Rural” comes from the word “Rurale” which means close to nature and environment, and “Development” means growth or maturation.

Rural development is utilization, protection and enhancement of the natural, physical and human resources to make long-term improvements in rural living conditions. It involves provision of jobs and income opportunities while maintaining and protecting the environment of rural areas.

a)     Development of human resource - It includes the development of rural people by providing education to the rural children and employment to rural youth, socio-economic condition of village can be improved.

b)     Expansion of physical resources - Construction of infrastructures like roads, schools, colleges, post office, bank etc will improve the rural condition.

c)     Extension of communit’s control over the resources.

OBJECTIVE OF EXTENSION EDUCATION

Objective

Objectives are expression of the ends towards which our efforts are directed.

The objective of extension is to develop the rural people economically, socially and culturaly by means of education. Overall, these objectives are divided into 4 types they are :

a)   Material objective

b)   Educational objective

c)   Social and cultural objective

d)   Developing leadership objective

a) Material objective

According to National Commission on Agriculture (1976). Agriculture extension aims at improving the efficiency of human capital, an effort to rapidly increase the rate of agricultural production. It also seeks to import necessary skill to farmer to understand the improved agricultural operation and improve the their own income, own resource and also the money value.

b) Educational objective

Extension education also aims at development of individual to change in behaviour by identifying their knowledge, skill, attitude and action. It aims at increasing the knowledge of people to analyse their past, present and expected future situation, to become aware of problem identification, solution and also realising their felt and unfelt need.

Extension

Extension is that type of education which is stretched out to people in rural areas far and near, beyond the limits of education institutions to which the formal type of education is usually confined.

Education

Education is a process of bringing about desirable changes in the behaviour of human being.

Formal education: The hierarchically structured, chronologically graded ‘education system’, running from primary school through the university and including, in addition to general academic studies, a variety of specialised programmes and institutions for full-time technical and professional training.

Informal education: The truly lifelong process whereby every individual acquires attitudes, values, skills and knowledge from daily experience and the educative influences and resources in his or her environment - from family and neighbours, from work and play, from the market place, the library and the mass media.

Non-formal education: Any organised educational activity outside the established formal system - whether operating separately or as an important feature of some broader activity - that is intended to serve identifiable learning clientele and learning objectives.

Over the past several years, there has been significant change in consumer perception on quality and food safety. Consumers are demanding healthy, nutritious and cost-effective products processed under controlled hygienic conditions. Food safety concern, in recent years, has become dominant and important. The requirement of food safety and quality assurance has never been so demanding as it is now. Globally food safety is being addressed independent of food quality. In anticipation of consumer demands on food safety, food sanitary standards at national and international levels are under constant review. Several inter governmental agencies/organizations are engaged in work related to quality assurance and food safety. Amongst these World Health Organization (WHO) and Codex Alimentarius Commission (CAC) play the major role in protecting public health and defining standards of quality and safety aspects of foods for regional and or world wide usage.

    1.    Cereals are grown over 73% of the total world harvested area and contribute over 60% of the world food production providing dietary fibre, proteins, energy, minerals,  vitamins, b-glucans , Oligosaccharides, such as lactulose, fructo-oligosaccharides, transgalacto-oligosaccharides

    2.    Finger millet is a potent source of antioxidants and has potent radical-scavenging activity that is higher than that of wheat, rice, and other millets; these results corresponded to their phenolic content

    3.    The brown or red variety of finger millet, which is commonly available, had higher activity (94%) than the white variety (4%) using the DPPH method.

    4.    Most of the herbal plant polyphenols are known to have multi functional properties such as reducing agents, hydrogen donating antioxidants and singlet oxygen quenchers and flavonoids and their derivatives are the largest and most important group of polyphenols.

    5.    Phytosterols are found in plant foods and are structurally and functionally analogous to cholesterol in vertebrate animals. a-sitosterol, campesterol and stigmasterol are the most commonly occurring phytosterols and constitute 95% of total phytosterols in the diet.

    1.    Wohler (1828) synthesized the first organic compound, urea from inorganic components.

    2.    Emil Fischer (1894) demonstrated the specificity of enzymes and the lock and key relationship between enzyme and substrate.

    3.    Michaelis and Menten (1913) developed kinetic theory of enzyme action

    4.    Watson and Crick (1953) Proposed the double-helical model for DNA structure

    5.    Ingo potrykus (1999) Golden rice- rich in b-carotene.

    6.    Glyoxysomes : Glyoxysomes are temporary in that they occur during transient periods in the life cycle of a plant such as in certain beans and nuts which store fats in their seeds as energy reserves. Glyoxysomes appear in the first few days after seed germination in endosperm cells and associate closely with lipid bodies. They disappear after the storage fats are broken down and converted into carbohydrate.

    1.    Control points are the points in the food processing chain where it is possible to control or remove hazards.

    2.    Critical control points are the control points in the processing chain where it is essential to a hazard, usually because there is no later step at which to establish control.

    3.    Preventative measures are the actions and activities needed to remove hazards or control them by reducing them to acceptable levels.

    4.    Critical limits for critical control points are measurements such as temperature and time, that must be met, or characteristics such as appearance and texture. Critical limits need to be validated.

    5.    Monitoring is the regular measurement or observation of a critical control point to ensure it is not beyond its critical limits.

    6.    Take corrective action to bring the process back under control before the problem (‘deviation’) leads to a safety hazard. Consider proper management (disposition) of any adversely affected product.

    7.    Verification procedures are tests and programmes that make sure the HACCP system working properly

    8.    Record keeping and documentation systems must meet the needs of the business and be adequate to show that the food safety programme is working.

Food Safety and Standards Rules and Regulations-2009

    1.    The Food Safety and Standards Act, 2006 has been passed by the Parliament with the intention to integrate all present food laws into one and to have a single regulatory body.

    2.    Accordingly the Food Safety and Standards Authority of India (FSSAI) has been established under the Food Safety and Standards Act, 2006 (FSS Act, 2006) with the mandate to lay down science based standards for articles of food and to regulate their manufacture, storage, distribution, sale and import, to ensure availability of safe and wholesome food for human consumption.

    3.    In exercise of the powers conferred by section 91 of the Food Safety and Standards Act, 2006 (34 of 2006), the Central Government hereby makes the rules and regulations.

    4.    ‘‘Anti-oxidant’’ means a substance which when added to food retards or prevents oxidative deterioration of food and does not include sugar, cereal, oils, flours, herbs and spices.

1. Food Labelling

Food labelling is the primary means of communication between the producer and seller of food on one hand, and the purchaser and consumer on the other.

Basic Terminology in Food labelling

‘‘Food” means any substance, whether processed, semi-processed or raw, which is intended for human consumption, and includes drinks, chewing gum and any substance which has been used in the manufacture, preparation or treatment of “food” but does not include cosmetics or tobacco or substances used only as drugs.

‘‘Ingredient” means any substance, including a food additive, used in the manufacture or preparation of a food and present in the final product although possibly in a modified form.

Hazard Analysis and Critical Control Point (HACCP) System

1. Identify hazards
 
 It is important to be able to identify the possible microbiological, chemical and physical hazards that can occur at every stage of the food business – from growth, processing, manufacture, storage and distribution, until the point where it is sold to the customer and eaten.

    ·    Microbiological Hazards : Any bacterium, virus, or protozoan that is capable of causing illness and that grows or may be carried on food. Well-known examples of bacteria are Campylobacter, Listeria and Salmonella. The most likely food-borne viruses are the Norwalk type viruses. Giardia is an example of a protozoan that may be food borne. It is important to have some understanding of the risks associated with different types of microbiological hazards.

    ·    Chemical Hazards : Examples include excessive or toxic amounts of heavy metals, chemicals, pesticides, herbicides, insecticides, vitamins, minerals, preservatives, disinfectants, detergents and cleaning compounds. Some hazards may be naturally present such as in green potatoes or taro and rhubarb leaves.

    ·    Physical Hazards : Objects that get into food, or are already present in food, may cause illness, injury or distress to the person eating it. Some examples are glass, metal fragments etc. Other contaminants such as hair or insects may be offensive but not necessarily a danger to health. They should nonetheless be considered and controlled

1. The Stability and Shelf-Life of Food

    1.    In the UK, the date coding to be used is determined by the total life of the product: for microbiologically highly perishable foods, a ‘use by’ date is needed, while for other foods, including foods with more than 18 months’ shelf-life, a ‘best before’ or a ‘best before end’ date is needed.

    2.    IFT (1974) definition of shelf-life, is : The period between manufacture and retail purchase of a food product during which the product is of satisfactory quality.

    3.    Shelf-life is defined as the time during which the food product will :

        i.    remain safe;
        ii.    be certain to retain desired sensory, chemical, physical and 
    microbiological characteristics;
        iii.    comply with any label declaration of nutritional data,
