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