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