Principles of Fresh Food Storage-1

Question 1
Marks : +2 | -2
Pass Ratio : 100%
The slope of the climacteric varies with _____
Maturity
Species
Oxygen and carbon-di-oxide content of the storage chamber
All of the mentioned
Explanation:
The slope of the climacteric varies with maturity, species and oxygen and carbon-di-oxide content of the storage chamber.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
Fleshy fruits after _____ are _____
Ripening, consumed
Ripening, rotted
Consuming, rotted
None of the mentioned
Explanation:
Fleshy fruits after ripening are consumed.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
Statement 1: Time is an important parameter for the growth of spoilage organisms.
True, False
True, True
False, False
False, True
Explanation:
Both, time and temperature are important parameters for the growth of spoilage organisms.
Question 4
Marks : +2 | -2
Pass Ratio : 100%
Statement 1: After harvest, there is a decline in the uptake of oxygen.
True, False
True, True
False, False
False, True
Explanation:
After harvest, there is a decline in the uptake of oxygen. This is followed by a sharp rise to a peak.
Question 5
Marks : +2 | -2
Pass Ratio : 100%
Statement 1: A harvested fruit contains many oxidative substrates required to perform respiration.
True, climacteric
True, botulism
False, climacteric
False, botulism
Explanation:
A harvested fruit contains many oxidative substrates required to perform respiration. Different species of fruits have different patterns of respiration. This is called as climacteric.
Question 6
Marks : +2 | -2
Pass Ratio : 100%
The length of storage of fruits and vegetables is a function of _____
Resistance to attack by microorganisms
Composition
Gases in the environment
All of the mentioned
Explanation:
All of the mentioned are factors which affect the length of storage of fruits and vegetables.
Question 7
Marks : +2 | -2
Pass Ratio : 100%
Statement 1: In the climacteric, the ratio of the highest peak to the minimum varies with temperature.
True, False
True, True
False, False
False, True
Explanation:
In the climacteric, the ratio of the highest peak to the minimum varies with temperature and varies from fruit to fruit.
Question 8
Marks : +2 | -2
Pass Ratio : 100%
Statement 1: At low temperatures, the rate of respiration of harvested fruits and vegetables decreases.
True, False
True, True
False, False
False, True
Explanation:
At low temperatures, the rate of respiration of harvested fruits and vegetables decreases. Under conditions where respiration rate is retarded, changes in chlorophyll loss are also delayed.
Question 9
Marks : +2 | -2
Pass Ratio : 100%
Statement 1: Ripening of fruits is accompanied with a lot of anabolic and catabolic reactions.
True, False
True, True
False, False
False, True
Explanation:
Ripening of fruits is accompanied with a lot of anabolic and catabolic reactions. Certain fleshy roots, tubers and bulbs have low metabolic activity and are dormant until there are environmentally favorable conditions for germination and growth.
Question 10
Marks : +2 | -2
Pass Ratio : 100%
In the climacteric, the ratio of the highest peak to the minimum _____ with temperature.
Increases
Decreases
Stays constant
Exponentially varies
Explanation:
In the climacteric, the ratio of the highest peak to the minimum increases with temperature.
