RBSE SS Voc Food Processing study plan

Define the ten preservation principles (high temperature, low temperature, water activity, acidity, redox potential, added preservatives, irradiation, mechanical separation, competitive flora, hurdle technology) and write a one-line definition of each from memory.

Compare blanching, pasteurisation, commercial sterilisation (including UHT), and canning in terms of target organisms, typical time-temperature combinations, and the quality damage each causes.

Explain the D-value, z-value, and 12D concept for Clostridium botulinum and calculate a required process time for a stated D-value and spore load.

Distinguish drying methods (sun, tray, drum, spray, freeze, osmotic) by operating principle, typical moisture end point, and one product suited to each.

Sketch a hurdle-technology example for a single product showing at least three hurdles and why each is necessary.

List the intrinsic (pH, moisture, water activity, nutrient content, antimicrobial constituents, biological structures) and extrinsic (temperature, relative humidity, gases) factors that govern microbial growth, and state the growth-limiting value for each.

Characterise the main spoilage and pathogenic groups (Pseudomonas, lactic acid bacteria, Bacillus, Clostridium, Staphylococcus aureus, Salmonella, Listeria monocytogenes, E. coli O157:H7, moulds, yeasts) by Gram reaction, oxygen need, heat resistance, and typical food vehicle.

Explain the difference between food infection, intoxication, and toxicoinfection with one named organism for each.

Describe how a cold chain, modified atmosphere, and water-activity reduction each suppress growth, and identify the failure mode of each.

Interpret a hypothetical microbial count result (total plate count, coliforms, yeast and mould) against a stated standard and recommend an action.

Label a wheat kernel diagram (bran, aleurone, endosperm, germ) and relate each fraction to milling yield and flour composition.

Compare dry milling and parboiling of rice, and state the effect of each on head rice recovery, thiamine retention, and cooking quality.

Explain the unit operations in pulse milling (pretreatment, conditioning, dehulling, splitting) and the causes of dhal loss.

Describe oil extraction by mechanical pressing and solvent extraction, then explain refining steps (degumming, neutralisation, bleaching, deodorisation) and what each removes.

Calculate a milling yield or extraction efficiency from given input and output masses.

Explain the roles of blanching, ascorbic acid, sulphiting, and hot fill in fruit and vegetable processing, and identify the quality problem each addresses.

Compare jam, jelly, squash, pickle, and dehydrated product manufacture by critical control point (pH, soluble solids, water activity, seal integrity).

Describe the stages of milk processing from reception to market milk, including clarification, homogenisation, pasteurisation, and the significance of the phosphatase test.

Outline the conversion of milk into curd, cheese, and ghee, naming the starter culture, coagulant, and key control parameter at each stage.

Summarise slaughter and dressing hygiene, post-mortem changes (rigor mortis, ageing), and the principles of chilling, freezing, and curing of meat, fish, and poultry.

Classify the macronutrients and micronutrients, and state the energy value of carbohydrate, protein, and fat and the function of each nutrient class.

Explain the Maillard reaction, caramelisation, and lipid oxidation, naming the conditions that promote each and how each is controlled in a real product.

Describe the proximate analysis scheme (moisture, ash, crude protein by Kjeldahl, crude fat by Soxhlet, crude fibre, nitrogen-free extract) and state what each determination measures.

Define water activity and relate it to moisture content, shelf life, and microbial limits.

Trace the historical development of food processing and distinguish food science from food technology and food processing as fields of study.

Match packaging materials (glass, tinplate, aluminium, paperboard, flexible laminates, PET) to product requirements for barrier, strength, and cost, and justify each choice.

Explain modified atmosphere packaging, vacuum packaging, aseptic packaging, and active packaging by mechanism and suitable product category.

Describe the main storage losses (moisture migration, insect infestation, rancidity, colour loss) and the control measure for each in a warehouse.

List the steps of a wet-cleaning and dry-cleaning sanitation programme, and state the concentration, contact time, and rinsing requirement for a caustic and a chlorine sanitiser.

Identify the personal protective equipment, machine-guarding, and chemical-handling controls required in a food processing hall, and explain lock-out/tag-out.

Explain the principles of HACCP (hazard analysis, critical control points, critical limits, monitoring, corrective action, verification, record keeping) and build a hazard analysis for one product.

Describe the roles of FSSAI, Codex Alimentarius, ISO 22000, and AGMARK, and state what each regulates or certifies.

Outline the statutory labelling requirements for a packaged food, including mandatory declarations and the nutrition panel.

Draft a simple business plan for a small food processing unit covering product, capacity, capital cost, raw material sourcing, and break-even quantity.

Explain the marketing mix for a processed food and identify two distribution channels suited to a small producer.

Re-attempt the weakest two domains identified in earlier weeks and correct every error in writing.

Answer a full-length timed mock paper under exam conditions and record the score per domain.

Review all worked calculations (thermal process time, milling yield, proximate analysis, break-even) until each can be done without notes.

Recite the preservation principles, pathogen control measures, and HACCP steps from memory in a single sitting.

Compile a one-page formula and definition sheet for final revision.
