  3. Food Products Technology.
  4. Food Engineering.

Section 1: Food Chemistry and Nutrition

Carbohydrates: Structure and functional properties of mono-, oligo-, & polysaccharides including starch, cellulose, pectic substances and dietary fibre, gelatinization and retrogradation of starch.

Proteins: Classification and structure of proteins in food, biochemical changes in post mortem and tenderization of muscles.

Lipids: Classification and structure of lipids, rancidity, polymerization and polymorphism.

Pigments: Carotenoids, chlorophylls, anthocyanins, tannins and myoglobin. Food flavours: terpenes, esters, aldehydes, ketones and quinines. Enzymes: specificity, simple and inhibition kinetics, coenzymes, enzymatic and nonenzymatic browning.

Nutrition: Balanced diet, essential amino acids and essential fatty acids, protein efficiency ratio, water-soluble and fat-soluble vitamins, the role of minerals in nutrition, co-factors, anti-nutrients, nutraceuticals, nutrient deficiency diseases.

Chemical and biochemical changes: Changes occur in foods during different processing.

Section 2: Food Microbiology

Characteristics of microorganisms: morphology of bacteria, yeast, mould and actinomycetes, spores and vegetative cells, gram-staining.

Microbial growth: growth and death kinetics, serial dilution technique. Food spoilage: spoilage
microorganisms in different food products including milk, fish, meat, egg, cereals and their products.

Toxins from microbes: pathogens and non-pathogens including Staphylococcus, Salmonella, Shigella, Escherichia, Bacillus, Clostridium, and Aspergillus genera.

Fermented foods and beverages: curd, yoghurt, cheese, pickles, soya-sauce, sauerkraut, idli, dosa, vinegar, alcoholic beverages and sausage.

Section 3: Food Products Technology

Processing principles: thermal processing, chilling, freezing, dehydration, the addition of preservatives and food additives, irradiation, fermentation, hurdle technology, intermediate moisture foods.

Food packaging and storage: packaging materials, aseptic packaging, controlled and modified atmosphere storage.

Cereal processing and products: milling of rice, wheat, and maize, parboiling of paddy, bread, biscuits, extruded products and ready to eat breakfast cereals.

Oil processing: expelling, solvent extraction, refining and hydrogenation.

Fruits and vegetable processing: extraction, clarification, concentration and packaging of fruit juice, jam, jelly, marmalade, squash, candies, tomato sauce, ketchup, and puree, potato chips, pickles.

Plantation crops processing and products: tea, coffee, cocoa, spice, extraction of essential oils and oleoresins from spices.

Milk and milk products processing: pasteurization and sterilization, cream, butter, ghee, ice cream, cheese and milk powder.

Processing of animal products: drying, canning, and freezing of fish and meat; production of egg powder.

Waste utilization: pectin from fruit wastes, uses of by-products from rice milling.

Food standards and quality maintenance: FPO, PFA, Agmark, ISI, HACCP, food plant sanitation and cleaning in place (CIP)
