BPVC-104 IGNOU Solved Assignment 2026-27

BPVC-104 Solved Assignment: Post-Harvest Management of Food Produce (TMA)

This digital PDF solution set is designed to fulfill the 30% mandatory course weightage for BPVC-104, aligning with IGNOU’s official curriculum for the Bachelor of Science (Food Safety and Quality Management) program. Below are key blocks addressed in the solved assignment, along with subject-specific FAQs.

Core Covered Syllabus Blocks (Official IGNOU Curriculum)

• Block-1: Food Physiology
  • Respiration, transpiration, and ethylene production in harvested produce.
  • Biochemical changes post-harvest: ripening, senescence, and nutrient degradation.
• Block-2: Post-Harvest Management
  • Harvesting techniques for fruits, vegetables, and cereals (timing, methods, and equipment).
  • Immediate post-harvest handling: cooling, grading, and sorting protocols.
• Block-4: Post-Harvest Management of Fruits and Vegetables
  • Storage conditions for perishable produce (temperature, humidity, and controlled atmosphere).
  • Packaging materials and their impact on shelf life (modified atmosphere packaging, MAP).
• Block-6: Post-Harvest Management of Cereals, Pulses, and Oilseeds
  • Drying, threshing, and winnowing techniques for grains.
  • Storage pests and chemical/biological control measures (silos, fumigation, and natural repellents).
• Block-5: Milk Collection, Transportation, and Storage
  • Hygienic milk collection practices and cooling methods (bulk tanks, chilling units).
  • Transportation standards (ISO containers, temperature monitoring, and sanitation).

Subject-Specific FAQs

• Q: How does ethylene gas affect post-harvest produce?

  A: Ethylene accelerates ripening in climacteric fruits (e.g., apples, bananas) but can cause premature senescence in non-climacteric produce (e.g., berries). Solutions include ethylene removal (e.g., potassium permanganate) or using ethylene inhibitors like 1-MCP.

• Q: What are the ideal storage conditions for oilseeds like groundnut?

  A: Oilseeds require low moisture (<8%), temperature (10–15°C), and controlled humidity (<60%) to prevent rancidity and mold growth. Aerated silos or metal bins with proper ventilation are recommended.

Assignment Structure & Compliance

The solved assignment adheres strictly to IGNOU’s word limits (500 words for long-answer questions, 250 words for medium-answer, and 100 words for short-answer) and includes:

• Step-by-step explanations for practical scenarios (e.g., designing a cold storage system for vegetables).
• Diagrams for processes like grading of fruits or milk cooling curves (where applicable).
• Case studies on real-world post-harvest losses (e.g., mangoes in India) with mitigation strategies.

Note: Solutions are verified against the latest eGyanKosh updates for BPVC-104 (academic session 2026-27) and include Hindi translations for non-English questions as per the course’s bilingual policy.

For submission deadlines, refer to the IGNOU Student Portal or Study Center announcements (typically 6–8 weeks from course enrollment).
