Food Safety and Standards Act, 2006 and Regulations
FSS Act 2006 repealed the Prevention of Food Adulteration Act 1954 and eight other laws; it established the Food Safety and Standards Authority of India (FSSAI) as the apex scientific and regulatory body.
Key authorities: Central Government issues regulations; FSSAI frames standards; State Food Safety Commissioners enforce; Designated Officers issue licences; Food Safety Officers inspect and sample.
Licence threshold: registration for petty food business (turnover up to Rs 12 lakh per year); state licence for turnover between Rs 12 lakh and Rs 20 crore; central licence for turnover above Rs 20 crore or for importers/exporters.
Adjudication: Designated Officer may adjudicate petty offences with penalty up to Rs 25,000; serious offences go to the Adjudicating Officer (penalty up to Rs 10 lakh); grievous injury or death cases are tried by Special Courts.
Penalties under FSS Act: substandard food – fine up to Rs 5 lakh; misbranded food – fine up to Rs 3 lakh; unsafe food – imprisonment up to 6 months and/or fine up to Rs 1 lakh; death due to unsafe food – imprisonment 7 years to life and fine not less than Rs 10 lakh.
Food Safety and Standards (Licensing and Registration of Food Businesses) Regulations, 2011 prescribe forms: Form A for registration, Form B for licence, Form C for licence certificate.
Food Safety and Standards (Packaging and Labelling) Regulations, 2011 mandate: name of food, list of ingredients, nutritional information, declaration of veg/non-veg, net quantity, lot/batch number, date of manufacture, best before/use by, name and address of manufacturer, and FSSAI logo with licence number.
Food Safety and Standards (Food Products Standards and Food Additives) Regulations, 2011 set maximum limits for additives, contaminants, toxins and residues; they also define standards for proprietary foods and novel foods.
Food Safety and Standards (Laboratory and Sample Analysis) Regulations, 2011 specify sampling procedures, recognised laboratories, and the requirement for analysis within 14 days of receipt of sample.
Food Microbiology and Food-Borne Pathogens
Bacterial growth curve phases: lag (adaptation), log/exponential (rapid multiplication), stationary (nutrient depletion, toxin accumulation), and death/decline phase.
Intrinsic factors affecting microbial growth: pH, water activity (aw), redox potential, nutrient content, antimicrobial constituents, and biological structures. Extrinsic factors: temperature, relative humidity, atmosphere, and competing microorganisms.
Minimum aw for growth: most bacteria 0.90; Staphylococcus aureus 0.86; most yeasts 0.88; xerophilic moulds 0.65. Below aw 0.60, no microbial growth occurs.
Cardinal temperatures: psychrophiles grow at 0–20°C (optimum 15°C); mesophiles 20–45°C (optimum 37°C); thermophiles 45–65°C (optimum 55°C). Most food-borne pathogens are mesophiles.
D-value: time at a given temperature to reduce microbial population by 90% (1 log). z-value: temperature change required to change D-value by a factor of 10. F0 value: equivalent time at 121.1°C to achieve a specified lethality.
Key food-borne pathogens: Salmonella (poultry, eggs), Listeria monocytogenes (dairy, ready-to-eat, psychrotrophic), Clostridium botulinum (canned low-acid foods, anaerobic, neurotoxin), Staphylococcus aureus (toxin preformed in food), Bacillus cereus (rice, emetic and diarrhoeal toxins), Escherichia coli O157:H7 (undercooked beef, Shiga toxin).
Clostridium botulinum spores are destroyed by heating at 121°C for at least 3 minutes (F0 = 3) in low-acid canned foods; toxin is heat-labile and destroyed by boiling for 10 minutes.
Indicator organisms: coliforms indicate hygiene and post-processing contamination; Escherichia coli indicates faecal contamination; aerobic plate count reflects overall microbial quality.
Food-borne viruses (norovirus, hepatitis A) and parasites (Toxoplasma, Cryptosporidium) are not destroyed by many preservation methods; they require thorough cooking or irradiation.
Food Chemistry
Water activity (aw) = p/p0, where p is vapour pressure of food and p0 is vapour pressure of pure water. Pure water has aw = 1.0; most fresh foods have aw > 0.95.
Maillard reaction: non-enzymatic browning between reducing sugars and amino groups of proteins at elevated temperature; favoured by high pH, high temperature, and low moisture. Produces melanoidins and flavour compounds.
Caramelisation: thermal decomposition of sugars without amines; occurs at high temperature and produces brown pigments and volatile flavour compounds.
Lipid oxidation: autoxidation via free radical chain reaction (initiation, propagation, termination). Pro-oxidants include light, heat, metals (Cu, Fe), and lipoxygenase; antioxidants (BHA, BHT, tocopherols) retard oxidation.
Protein denaturation: loss of native conformation due to heat, pH extremes, or shear; primary structure (peptide bonds) remains intact. Coagulation follows denaturation.
Enzymatic browning: polyphenol oxidase catalyses oxidation of phenols to quinones, which polymerise to brown melanins; blanching inactivates the enzyme in fruits and vegetables.
Starch gelatinisation: heating starch in water causes granule swelling and irreversible loss of crystallinity; gelatinisation temperature range for most starches is 60–75°C.
pH scale: pH = –log[H+]. Food pH ranges: citrus fruits 2–3; meat 5.5–6.5; egg white 7.6–8.0; milk 6.5–6.7.
Essential amino acids (9): histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine. Limiting amino acid in cereals is lysine; in pulses it is methionine.
Nutrition and Adulteration Testing
Macronutrient energy values (Atwater): carbohydrate 4 kcal/g, protein 4 kcal/g, fat 9 kcal/g, alcohol 7 kcal/g, dietary fibre 2 kcal/g.
Balanced diet: carbohydrates 55–60% of energy, fats 20–30%, proteins 10–15%. Protein requirement for adults is 0.8–1.0 g/kg body weight per day.
Fat-soluble vitamins: A, D, E, K (stored in liver and adipose tissue; toxic in excess). Water-soluble vitamins: B-complex and C (excreted in urine; deficiency develops faster).
Common adulterants and tests: starch in milk – iodine test (blue colour); urea in milk – urease test or DMAB test; detergent in milk – shaking produces lather; metanil yellow in turmeric – hydrochloric acid test (magenta colour); argemone oil in mustard oil – nitric acid test (red colour); sawdust in chilli powder – floating on water.
Kjeldahl method for protein: digestion with sulphuric acid, distillation of ammonia, titration; crude protein = nitrogen × 6.25 (factor varies: 5.7 for wheat, 6.38 for milk).
Soxhlet extraction for fat determination uses petroleum ether or hexane as solvent; fat content is determined gravimetrically after solvent evaporation.
Food additives and their INS numbers: preservatives (INS 200–299), antioxidants (300–399), thickeners/emulsifiers (400–499), anti-caking agents (500–599), flavour enhancers (600–699), sweeteners (950–969).
Adulteration under FSS Act: food is adulterated if it contains any substance that makes it injurious to health, or if it is unfit for human consumption due to filth, decomposition, or contamination.
Recommended Dietary Allowances (RDA) for Indians: energy 2,320 kcal/day for sedentary adult male, 1,900 kcal/day for sedentary adult female (ICMR 2020).
Food Processing, Preservation and Packaging Technology
Blanching: brief heat treatment (70–100°C) of fruits and vegetables to inactivate enzymes (polyphenol oxidase, peroxidase) and remove air, prior to freezing or drying.
Pasteurisation: heat treatment below 100°C (e.g., 63°C for 30 min or 72°C for 15 s for milk) to destroy vegetative pathogens and reduce spoilage organisms; does not sterilise.
Sterilisation (commercial): heat treatment above 100°C (typically 115–121°C) to destroy all microorganisms and spores; used for canned low-acid foods.
Freezing: preservation by reducing temperature below 0°C; microbial growth stops but enzymes remain active unless blanched. Quick freezing produces smaller ice crystals and better texture.
Drying and dehydration: removal of water to aw below 0.60; sun drying, tray drying, spray drying, freeze drying (lyophilisation), and osmotic dehydration.
Irradiation: use of ionising radiation (gamma rays, electron beams, X-rays) to extend shelf life and control pathogens; doses measured in Gray (Gy); approved up to 10 kGy for certain foods.
Modified Atmosphere Packaging (MAP): replacement of air with gases (CO2, N2, O2) to extend shelf life; CO2 inhibits bacteria and moulds; N2 is an inert filler; O2 maintains red meat colour and inhibits anaerobes.
Aseptic packaging: filling of commercially sterile product into pre-sterilised containers under sterile conditions; commonly used for UHT milk and juices.
Packaging materials: glass (inert, impermeable, heavy), metal (tinplate, aluminium; good barrier, opaque), paper/board (light, recyclable, poor barrier), plastics (PET, HDPE, LDPE, PP, PS, PVC; varying barrier and heat resistance).
Food Hygiene, Sanitation and Quality Management Systems (HACCP, GMP, ISO 22000)
HACCP seven principles: (1) conduct hazard analysis, (2) determine critical control points (CCPs), (3) establish critical limits, (4) establish monitoring procedures, (5) establish corrective actions, (6) establish verification procedures, (7) establish record-keeping and documentation procedures.
CCP decision tree: a sequence of questions to determine whether a control point is a CCP; considers hazards, control measures, and whether the step eliminates or reduces the hazard to an acceptable level.
Critical limit: a measurable value (e.g., temperature, time, pH, aw) that separates acceptability from unacceptability at a CCP.
Good Manufacturing Practices (GMP): prerequisite programmes covering personnel hygiene, plant and equipment design, sanitation, pest control, and training; GMP is the foundation for HACCP.
Sanitation Standard Operating Procedures (SSOP): documented procedures for cleaning and sanitising food-contact surfaces, equipment, and premises; eight key sanitation areas include water safety, food-contact surface condition, cross-contamination prevention, hand washing, and pest control.
ISO 22000: international standard for food safety management systems; integrates HACCP principles with prerequisite programmes and management system requirements; applicable to all organisations in the food chain.
Cleaning vs sanitising: cleaning removes soil (detergents); sanitising reduces microorganisms to safe levels (heat, chemicals such as chlorine, quaternary ammonium compounds).
Personal hygiene: hand washing with soap and water for at least 20 seconds; food handlers must not work with exposed food if suffering from jaundice, diarrhoea, vomiting, fever, or infected skin lesions.
Pest control: integrated pest management (IPM) uses exclusion, sanitation, and targeted chemical control; rodenticides and insecticides must be used away from food and food-contact surfaces.
Food Inspection, Sampling, Licensing and Enforcement Procedure
Food Safety Officer (FSO) powers: inspect premises, take samples, seize adulterated food, and launch prosecution; must give notice in writing (Form V) to the person from whom sample is taken.
Sampling procedure: divide sample into four parts, seal each part, send one part to the Designated Officer, one to the Food Analyst, one to the person from whom sample is taken, and retain one for court reference.
Food Analyst must analyse the sample and issue a report in Form VI within 14 days of receipt; if analysis is not possible, the sample must be sent to a referral laboratory.
If the Food Analyst report shows non-compliance, the Designated Officer may issue an improvement notice (Form VII) or prohibit sale of the food article.
Appeal against Food Analyst report: the person may request the Designated Officer to send the sample to a referral laboratory within 15 days of receipt of the report.
Licensing procedure: application in Form B to the Designated Officer; inspection by FSO; licence granted in Form C within 60 days if requirements are met; licence valid for 1 to 5 years.
Registration: petty food business applies in Form A to the Registering Authority; registration certificate issued in Form D; registration valid for 1 to 5 years.
Enforcement: FSO files prosecution in the Special Court; the Adjudicating Officer imposes penalties for offences not punishable with imprisonment; appeals lie to the Food Safety Appellate Tribunal.
Seizure: FSO may seize any food article that appears to be unsafe or misbranded; a seizure memo (Form VIII) is prepared and signed by witnesses.

Analytical Ability, Reasoning and Quantitative Aptitude
Percentage: to find x% of y, compute (x/100) × y. Percentage change = [(new value – old value) / old value] × 100.
Ratio and proportion: if a:b = c:d, then ad = bc. To divide a quantity Q in ratio a:b:c, parts are Qa/(a+b+c), Qb/(a+b+c), Qc/(a+b+c).
Average: average = sum of observations / number of observations. If each observation is increased by k, the average increases by k.
Profit and loss: profit% = (profit / cost price) × 100; selling price = cost price × (100 + profit%)/100; discount% = (discount / marked price) × 100.
Simple interest: SI = (P × R × T)/100. Compound interest: CI = P[(1 + R/100)^T – 1].
Time, speed and distance: speed = distance / time; if speed ratio is a:b, time ratio for same distance is b:a; average speed for equal distances = 2xy/(x+y).
Permutation and combination: nPr = n!/(n–r)!; nCr = n!/[r!(n–r)!]; number of diagonals in an n-sided polygon = n(n–3)/2.
Logical reasoning: syllogism – use Venn diagrams; statement and conclusion – evaluate validity; coding-decoding – identify pattern; blood relations – draw family tree.
Data interpretation: read tables, bar charts, line graphs, and pie charts; calculate percentages, ratios, and averages accurately; pay attention to units and scales.
