Postharvest Technology MCQs (Set 13) Posted on August 24, 2026Author agropublishers 0 1. Ethylene management is particularly important in postharvest handling because ethylene _______________ Prevents all microbial growth Regulates ripening in climacteric fruits Increases water content Stops respiration completely 2. NIR spectroscopy is particularly useful for non-destructive estimation of __________________ of fruits Package design Insect species by visual observation Fruit weight Dry matter, total soluble solids (TSS), moisture, and maturity 3. Proper packaging of fruits and vegetable contributes to postharvest disease management mainly by _____________ Increasing bruising Preventing mechanical injury and compression Increasing contamination Raising water loss 4. During dehydration of sliced tomatoes, which adjustment can help prevent case hardening? Reduce airflow to keep the surface moist Add more salt before drying Start at a lower drying temperature with good airflow Increase the drying temperature further 5. A ____________________ spreads throughout the vascular or internal plant system Systemic infection Mechanical infection Secondary infection Latent infection 6. Which novel preservation technology can preserve fresh-cut vegetables with minimal heat damage? Sun drying and cloth-bag storage Traditional high-temperature canning High-pressure processing (HPP) of refrigerated products Boiling and room-temperature storage 7. Which situation presents the greatest risk of rapid postharvest disease development? Bruised fruit stored under warm, humid conditions Properly cured bulbs under appropriate conditions Intact fruit stored at low relative humidity Rapidly cooled undamaged fruit 8. Cold storage reduces postharvest decay of fruits, mainly because low temperature ___________________ Speeds pathogen growth Eliminates the need for hygiene Always causes freezing injury Slows respiration and the growth of many pathogens 9. Which group consists of non-climacteric fruits? Banana, mango, papaya Strawberry, grape, citrus Mango, banana, apple Apple, pear, tomato 10. Plant pathogen __________ causes gray mold on many fruits and vegetables Rhizopus stolonifer Fusarium oxysporum Penicillium expansum Botrytis cinerea Loading … Question 1 of 10
