Harvesting Methods Flashcards
Why is early harvesting disadvantageous?
The fruits and veggies may not reach its final optimal size, shape, and weight = low yield
What happens when produce are harvested early?
Carbohydrates and primary sugar accumulation
Loss of acid and astringent substances
Cell wall degradation
And underdevelopment of aroma
Underdeveloped skin color
What happens when cuticular and lenticular development is not completed?
Weight less due to water loss; easily wrinkled skin
Is fungal decay common in over mature produce?
Yes
Why is there an inferiority in taste when harvested late?
Severe reduction in acidity and flavor
What are the causes of damaged crops during harvesting?
Bruising from compression
Impact
Vibration
This harvesting method is less expensive, renders low damage, and increased harvest rate but is time consuming
Hand Harvesting
Two types of mechanical harvesting
Mechanical Assistance
Harvesting Machines
How do we prolong retention of good quality after harvesting?
Reduce metabolic activities through treatments and handling operations
How long does a fruit or vegetable last before deterioration starts?
minimum 1hr
What step is used to reduce bruise damage after harvesting?
Precooling
It is an effective operation to reduce water loss during storage of hardy vegetables (onion, garlic, ssweet potato)
Curing
This postharvest step helps in healing of harvest injuries, reduce water loss, prevent infection by decay pathogens
Curing
Can waxing improve the quality of any inferior horticulture?
No. It just helps as a beneficial adjunct to good handling.
This is an indicator of fresh quality produce where mandatory standards are established by federal state
