APPSC FSO cheat sheet

Water activity (aw) measures unbound water available for microbial growth; most bacteria require aw above 0.90, most molds tolerate down to about 0.80, and halophilic bacteria can grow near 0.75.

Maillard browning is a non-enzymatic reaction between reducing sugars and amino groups; it accelerates above pH 7 and at higher aw, and is retarded by sulfur dioxide and low temperature.

Caramelization differs from Maillard: it is sugar pyrolysis without amines, producing furan derivatives, diacetyl, and brown pigments at temperatures above roughly 150 °C.

Iodine value measures unsaturation of fats (g iodine per 100 g fat); saponification value reflects average chain length; peroxide value indicates primary oxidation, while anisidine value tracks secondary aldehydes.

Kjeldahl nitrogen × 6.25 estimates crude protein; the factor is 6.38 for milk and 5.70 for wheat flour because of their different nitrogen-to-protein ratios.

Soxhlet extraction with petroleum ether gives crude fat; the Gerber and Babcock methods estimate milk fat by acid digestion and centrifugation.

Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) separates proteins by molecular weight, while high-performance liquid chromatography (HPLC) quantifies vitamins, additives, and mycotoxins with UV or fluorescence detection.

In atomic absorption spectroscopy, a hollow cathode lamp emits element-specific light and Beer-Lambert law relates absorbance to concentration; graphite furnace mode reaches ppb levels for lead and cadmium.

Clostridium botulinum is an anaerobic, spore-forming, Gram-positive rod; its neurotoxin is destroyed by boiling for 10 minutes, but spores require 121 °C (F0 = 12 D) for commercial sterility in low-acid canned foods.

Staphylococcus aureus produces heat-stable enterotoxin; cooking kills the organism but not the toxin, so rapid cooling and exclusion of food handlers with skin infections are critical controls.

Salmonella is controlled by thorough cooking to 74 °C internal temperature; the infectious dose can be as low as 10^2 cells in high-fat foods such as chocolate.

Listeria monocytogenes grows at refrigeration temperatures (4 °C) and tolerates 10% NaCl; ready-to-eat foods must have zero tolerance in 25 g under Indian standards.

Aflatoxins B1, B2, G1, G2 are produced by Aspergillus flavus and A. parasiticus; B1 is the most hepatotoxic and is metabolized to the epoxide that binds DNA.

The D-value is the time at a given temperature to reduce a microbial population by 90%; the z-value is the temperature change needed to alter the D-value tenfold.

Coliforms and Escherichia coli are indicator organisms for fecal contamination; their absence in 100 mL drinking water is a basic potability criterion.

Mycotoxin limits under FSSAI: total aflatoxin in cereals and pulses is 30 µg/kg and aflatoxin M1 in milk is 0.5 µg/kg.

Blanching inactivates polyphenol oxidase and peroxidase, removes entrapped air, and fixes colour before freezing or canning; peroxidase is the more heat-stable indicator enzyme.

Commercial sterilization targets a 12-log reduction of Clostridium botulinum spores (12D concept), while pasteurization of milk at 72 °C for 15 seconds achieves a 5-log reduction of Coxiella burnetii.

Freezing preserves by lowering water activity and temperature; quick freezing forms small intracellular ice crystals that minimize drip loss and tissue damage.

Spray drying atomizes liquid feed into hot air; inlet temperatures of 150-220 °C and outlet temperatures of 80-90 °C are typical for milk powder.

Osmotic dehydration uses high-sugar or high-salt solutions to lower aw; it is used for candied fruits and intermediate-moisture foods.

Extrusion cooking combines shear, heat, and pressure to gelatinize starch and denature protein, producing snacks and textured vegetable protein in seconds.

Modified atmosphere packaging lowers oxygen to 2-5% and raises carbon dioxide to 5-10% to extend shelf life of fresh produce and meat.

Hurdle technology combines multiple preservative factors, such as aw, pH, redox potential, and temperature, so no single factor must be severe.

The Food Safety and Standards Act, 2006 consolidated eight earlier laws, including the Prevention of Food Adulteration Act, 1954, and established FSSAI as the apex regulator.

FSSAI's chairperson is appointed by the Central Government; the Food Authority has 22 members, and the Central Advisory Committee advises it.

Section 3 defines food broadly to include processed, partially processed, genetically modified, and packaged drinking water; 'unsafe food' is defined under Section 3(1)(zz).

Adjudicating officers decide penalties under Section 68; the State Commissioner of Food Safety is the appellate authority for adjudication orders, and appeals from that go to the Food Safety Appellate Tribunal.

Penalties: adulteration with a foreign substance can attract imprisonment up to six months and a fine up to ₹1 lakh under Section 59; grievous injury cases attract up to seven years under Section 59(ii).

Section 31 requires a licence for food business operators above the threshold turnover; petty manufacturers and temporary stallholders register under Section 31(1)(a).

The Food Safety and Standards (Licensing and Registration of Food Businesses) Regulations, 2011 set the turnover and capacity thresholds for registration versus licence.

Section 46 empowers food safety officers to seize, sample, and inspect; a sample is divided into four parts, and the analysis report must be supplied within 14 days of receipt.

Hazard Analysis and Critical Control Points (HACCP) has seven principles: hazard analysis, CCP determination, critical limits, monitoring, corrective actions, verification, and record keeping.

A critical control point is a step where a control measure can prevent, eliminate, or reduce a significant hazard to an acceptable level; critical limits must be measurable, such as 72 °C for 15 seconds.

ISO 22000 integrates HACCP with prerequisite programmes and ISO 9001 principles; ISO/TS 22002 provides prerequisite programme requirements for food manufacturing.

Good Manufacturing Practices cover premises, equipment, personnel hygiene, and process control; Good Hygiene Practices focus on cleaning, sanitation, and pest control.

The Food Safety and Standards Authority of India mandates Food Safety Management System certification for certain categories, such as milk and meat processing, under Schedule 4 of the Licensing Regulations.

An internal audit follows the plan-do-check-act cycle; non-conformities are classified as major or minor, and corrective actions must address root cause, not just symptoms.

Traceability under FSSAI requires one step back and one step forward; records must allow recall of a batch within four hours of a decision.

India's certification marks include AGMARK for agricultural produce, BIS certification for packaged drinking water, and FSSAI licence numbers displayed on labels.

Seizure of food articles is governed by Section 46; perishable articles may be disposed of with the adjudicating officer's permission after sampling.

Surveillance uses risk-based inspection, and FSSAI's State Food Safety Index ranks states on compliance, testing infrastructure, and human resources.

Adulteration offences are compoundable except where the offence involves grievous injury or death; penalties are recovered as arrears of land revenue.
