GATE Food Technology Syllabus- Section 1: Food Chemistry and Nutrition

Carbohydrates: The structure and functional properties of mono-, oligo-, and polysaccharides such as starch, cellulose, pectic substances, and dietary fiber, as well as gelatinization and starch retrogradation.

Proteins: classification and structure of proteins in food, biochemical changes in postmortem, and tenderization of muscles.

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

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

Nutrition: 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: Food undergoes changes as a result of various processing methods.

Section 2: Food Microbiology

Characteristics of microorganisms: morphology of bacteria, yeast, mold 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, yogurt, 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, and 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)

Section 4: Food Engineering

Mass and energy balance: Flow rate and pressure drop relationships for Newtonian fluids flowing through a pipe, Reynolds number

Heat transfer: heat transfer by conduction, convection, radiation, heat exchangers.

Mass transfer: molecular diffusion and Fick’s law, conduction and convective mass transfer, permeability through single and multilayer films.

Mechanical operations: size reduction of solids, high-pressure homogenization, filtration, centrifugation, settling, sieving, mixing & agitation of liquid.

Thermal operations: thermal sterilization, evaporation of liquid foods, hot air drying of solids, spray and freeze-drying, freezing, and crystallization.

Mass transfer operations: psychrometry, humidification, and dehumidification operations.

Conclusion

During the preparation of the Food Technology examination, we advise you to focus on the GATE Food Technology Syllabus and prepare a strategy accordingly. Additionally, it is important to follow a credible and reliable set of study materials for your preparation. Do not build a stack of books and create unnecessary pressure. Instead, keep relevant books and revise them repeatedly.

Do not lose focus and maintain a healthy lifestyle.

We wish you the best in everything!
