Postharvest Technology MCQs (Set 14) Posted on August 24, 2026Author agropublishers 0 1. The primary purpose of packaging fresh horticultural produce is to _____________ Eliminate the need for refrigeration Increase crop yield Protect, contain, facilitate handling, and preserve quality Increase produce respiration 2. Overfilling a carton of mangoes is most likely to cause ___________________ Improved ventilation Compression injury and bruising Reduced compression Reduced package weight 3. Loading warm produce into a refrigerated truck can result in __________________ Excessive refrigeration load and difficulty maintaining the desired temperature Improved shelf life Immediate uniform cooling Reduced respiration immediately 4. ________________________ is a new disease attack that develops after the initial disease has become established Latent infection Systemic infection Mechanical infection Secondary infection 5. Ventilation holes in fresh-produce cartons primarily facilitate _____________ Increased mechanical injury Heat removal and refrigerated-air circulation Elimination of respiration Complete prevention of water loss 6. Excessive ventilation in a fresh-produce package may result in ____________________ Increased shelf-life in every commodity Complete elimination of decay Anaerobic respiration Increased moisture loss and shrivelling 7. Which packaging function primarily prevents bruising, abrasion, puncture, and crushing of fresh produce? Marketing Protection Communication Containment 8. Among the environmental factors _____________ and ____________ are primarily important in the development and spread of postharvest diseases Temperature and relative humidity Wind speed and photoperiod Soil pH and texture Light and photoperiod 9. Why can reducing mechanical damage be more effective for postharvest disease management than applying fungicides after harvest? Fungicides increase wound formation Many postharvest pathogens depend on wounds as primary infection courts Mechanical damage has no relationship with infection Wounds inhibit pathogen development 10. Which postharvest practice effectively reduces transpiration and maintains fruit freshness? Increasing air movement Increasing storage temperature Removing all packaging Using appropriate packaging to reduce water loss Loading … Question 1 of 10
