UPMSP Class 12 Food & Fruit Preservation - Code 202 study plan

List the eight domain weightings and convert each into an exam-time budget, then rank the four heaviest domains to sequence your revision

Define food science, food preservation and spoilage in your own words and distinguish between microbial, enzymatic, chemical and physical spoilage with one concrete food example each

Identify the intrinsic factors of food (pH, water activity, redox potential, nutrient content, antimicrobial constituents) and predict which foods spoil fastest

Identify the extrinsic factors (temperature, relative humidity, gases, competing microflora) and explain how each is manipulated in preservation

Sketch a one-page business idea for a small fruit-processing unit and name the preservation principle it relies on

Explain the twelve principles of food preservation and match each to at least one commercial process

Distinguish bactericidal from bacteriostatic effects and predict the outcome of combining two hurdles (for example low pH plus heat)

Compare blanching, pasteurization and sterilization in terms of temperature range, target organisms and effect on nutrients

Draft a cost sheet for a small jam or squash unit covering raw material, sugar, preservative, packaging, labour and overhead

Compute a simple break-even quantity from fixed and variable costs

Describe the composition and maturity indices used to harvest mango, guava, tomato and citrus, and state why maturity matters for processing

Explain the steps of juice extraction, clarification, filtration and concentration, and name the equipment used at each step

Compare pulp, squash, cordial, syrup, RTS beverage and nectar by pulp percentage, TSS and acidity

Outline jam, jelly, marmalade and preserve making, and explain the roles of pectin, sugar, acid and the setting point test

Describe the causes of browning in cut fruits and state three methods to control it

Explain the science of canning: exhaust, headspace, seam formation, thermal death time and the 12-D concept in plain language

Classify foods by pH into acid, acidified and low-acid groups and state the required process severity for each

Compare boiling-water, atmospheric steam and pressure processing, and identify which foods require a pressure retort

List the causes of spoilage in canned products (under-processing, leakage, flat-sour, thermophilic, hydrogen swell) and the tell-tale signs of each

Describe the steps of bottling and sterilization of bottles, including crown capping and cooling

Explain the difference between drying and dehydration and describe sun, solar, cabinet, tunnel, drum and freeze drying

Interpret a drying curve and sorption isotherm qualitatively, and relate water activity to shelf life and microbial growth

Explain osmotic dehydration and the role of pre-treatments such as blanching, sulphiting and lye peeling

Describe low-temperature preservation: chilling, refrigeration, freezing, and the difference between slow and quick freezing on ice crystal size and texture

List common drying defects (case hardening, browning, vitamin loss) and their remedies

Classify preservatives into Class I and Class II and state permitted levels and the legal status of common ones (benzoic acid, sulphur dioxide, sorbic acid, salt, sugar)

Explain the mechanism of chemical preservatives, including pH dependence of benzoate and sulphite, and why overuse is a safety and legal issue

Describe the role of salt, sugar, acid and smoke as preservatives and their effect on water activity and microbial inhibition

Distinguish lactic, acetic and alcoholic fermentation and name the organisms and typical products of each

Explain how fermentation preserves food and list common fermented fruit and vegetable products

Compare packaging materials (glass, tinplate, aluminium, PET, laminates, aseptic cartons) for barrier properties, cost and suitability

Explain labelling requirements for a packaged food: mandatory declarations, FSSAI licence number, veg/non-veg mark, net quantity and best-before

Describe quality control tests for a fruit product: TSS, acidity, pH, colour, texture and microbiological limits

Outline the principles of HACCP and GMP and identify three critical control points in a jam or juice line

Explain safe storage conditions and the effect of temperature, light and humidity on stored products

Build a project report outline for a small fruit-processing venture: product, process, plant and equipment, cost, market and food-safety compliance

Explain marketing mix, distribution channels and pricing for a small food business, and identify two government support schemes you can name confidently

Solve two numerical problems each on break-even, preservative dilution and TSS adjustment under timed conditions

Attempt one full-length timed mock paper and log every wrong answer by domain

Re-drill only the logged weak areas and write a one-page final revision sheet
