Fruit Ripening Flashcards
It is a dramatic event in the life of a fruit as it transforms a physiologically mature but inedible plant organ into a visually attractive olfactory and taste sensation.
Ripening
It is the process where degradation of the flesh allows the mature seed to be released for germination.
Ripening
True or False
Some temperate fruits require cool storage to simulate wintering period to activate germination.
True.
What does a fruit undergo during ripening?
Changes in cell wall structure
Pigment Accumulation
Flavor and aromatic volatile production
Conversions of starches to sugars
The key plant hormone
Ethylene
What are the factors that affect the activity of ACC synthase?
The timing of fruit ripening
Senescence
Physical Injuries and chilling injury
It is the largest quantitative associated with ripening
Breakdown of carbohydrate = total conversion starch to sugars
Do organic acids decline during ripening?
Yes. Because acids are reserve sources of energy to fruit and thus decline during greater metabolic activity during ripening
What is the only fruit that experience highest acid level at fully ripe stage?
Banana
Is the eating quality determined by flavor and texture or by physiological age?
Flavor and texture
