Postharvest Technology MCQs (Set 17) Posted on August 24, 2026Author agropublishers 0 1. In grading operations, it is important to separate mechanically injured produce because _____________________________ Injured produce cannot be washed or waxed Injured produce always weighs more than sound produce Sound produce must be stored at higher temperatures Injured produce deteriorates faster and can spread decay 2. Latent infections are particularly difficult to detect in harvested fruits because ________________ They remain symptomless until favorable conditions or ripening occur They spread only through soil They are always associated with wounds They occur only on leaves 3. _______________ is the most suitable and efficient precooling method for leafy lettuce packed loosely in cartons Top-icing with crushed ice Hydrocooling by immersion Room cooling without forced airflow Vacuum cooling 4. The primary advantage of electronic sizing equipment for citrus is ___________________ Ability to completely prevent mechanical damage during handling Reduced need to wash and wax fruit before packing Elimination of the need for grading based on defects Improved accuracy and consistency in size classification 5. __________________________________________ best prevents mechanical injury and maintains cooling airflow in cold storage Placing heavy pallets on lighter ones Stacking pallets tightly to maximize capacity Avoiding over-tight stacking and leaving space between pallets Allowing forklifts to bump pallets for faster alignment 6. Postharvest disease is best defined as deterioration caused primarily by _____________ Temperature stress Nutritional imbalance Water loss Pathogenic microorganisms 7. The characteristic blue-green sporulation of blue mold on stored apples is produced by ________________ Alternaria alternata Botrytis cinerea Penicillium expansum Fusarium spp. 8. Root and tuber crops require curing after mechanical damage to ___________________ Promote wound healing and reduce bacterial decay Increase respiration Accelerate sprouting Increase water loss 9. _____________________________ is the best practice to minimize cross-contamination and mechanical injury when washing leafy vegetables Using very warm water to remove soil more quickly Allowing leaves to soak for long periods in still water Using clean, cool water with properly controlled sanitizer levels Agitating leaves vigorously to ensure thorough cleaning 10. A fresh-cut carrot processor wants to minimize mechanical injury during slicing and dicing. Which strategy is most effective? Using dull blades Adding more workers for manual handling Using sharp, well-maintained blades and controlled feed rates Increasing feed speed Loading … Question 1 of 10
