Preservation methods, canning, processed products, FPO standards, and post-harvest management for competitive exams.
Post-harvest technology deals with handling, grading, storage, transport, processing, and preservation of produce after harvest so that quality is maintained and quantitative as well as qualitative losses are reduced.
It is important because a large share of crop value depends on storage life, transport safety, processing, and marketability. Exams commonly ask about cold chain, preservation methods, maturity indices, processing products, and loss reduction.
Pre-cooling quickly removes field heat after harvest, cold storage keeps produce at suitable low temperature for longer life, and processing converts raw produce into products such as juice, jam, pickle, dehydrated foods, or canned items.
Focus on storage principles, respiration and transpiration, preservation methods, canning and dehydration, cold chain terms, processed products, and causes of post-harvest losses in fruits, vegetables, and grains.
