Food & Fruit Preservation (Code 202) is a vocational subject in the Uttar Pradesh Madhyamik Shiksha Parishad (UPMSP) Intermediate curriculum. It is designed for Class 12 students who want practical, employable skills in processing and preserving fruit and vegetables - not only for board marks but as a route into small-scale food enterprise, cottage industry, or further study in food technology and home science. The UPMSP Class 12 Food & Fruit Preservation - Code 202 study guide has 9 sections and about 2,873 words.
01Introduction to Food Science and Food Spoilage
This domain checks whether you can link food composition to keeping quality and name the agent responsible for a spoilage symptom. Questions often ask you to classify a food by perishability or to pick the factor that allowed a spoilage organism to grow.
348 words, about 2 min02Principles and Methods of Food Preservation
The exam asks you to state the classical principles of preservation, place a given method under the correct principle, and explain why a combination of methods is used. Prevention or delay of microbial decomposition: asepsis (clean handling, sterile packaging), removal of microorganisms (filtration, centrifugation), hindering growth (low temperature, drying, chemicals, anaerobic storage) and killing (heat, irradiation).
310 words, about 2 min03Fruit and Vegetable Processing Technology
Expect questions on unit operations from washing to filling, the composition standards of jam, jelly, squash and ketchup, and the causes of failed products. Receiving, sorting, grading, washing, peeling (manual, steam, lye, abrasive), trimming, cutting, blanching, pulping, juice extraction, finishing, deaeration, homogenization, pasteurization and filling.
310 words, about 2 min04Preservation by Heat: Canning, Bottling and Sterilization
This domain tests thermal death kinetics, the canning sequence, the acidity rule that decides whether a pressure retort is needed, and the identity of spoilage types. D value: time at a given temperature to reduce the population by 90%.
335 words, about 2 min05Preservation by Low Temperature
Questions cover refrigeration temperatures, chilling injury, controlled atmosphere storage, freezing rate and the changes that occur during frozen storage. Refrigeration generally means 0-7°C; cold storage for apples is often 0-2°C.
312 words, about 2 min06Drying and Dehydration
This domain tests the difference between sun drying and controlled dehydration, the drying curve, pretreatments, and calculations of final weight and water removal. Sun drying is cheap but slow and weather-dependent.
316 words, about 2 min07Preservation by Chemicals, Preservatives and Fermentation
You must classify preservatives, state their permitted limits and effective pH range, calculate preservative doses, and explain the microbiology of pickling and fermentation. Class I: salt, sugar, vinegar, spices, honey and edible oil; used as normal ingredients without a stated maximum.
320 words, about 2 min08Packaging, Storage, Quality Control and Food Safety
This domain tests packaging material choice, storage practice, the seven HACCP principles, food hazards, certification marks and mandatory labelling. Packaging contains, protects, preserves, informs and gives convenience.
304 words, about 2 min09Entrepreneurship, Marketing and Practical/Project Work
This domain tests costing, break-even, licences and marketing basics, plus laboratory skills used in a project report on a fruit product. A business plan covers the product, market survey, SWOT analysis, production plan, costing, pricing, marketing mix and finance.
