Discussion
All perishable food commodities are stored in cold storage in the temperature range from_____
Answer: A
The key gives the range 16 to -2 °C.
Cold storages for perishable produce operate above freezing, or just below it, at temperatures chosen for each commodity: around -1 to 2 degrees for apples, grapes and many leafy vegetables, about 2 to 4 degrees for potatoes, and up to about 10 to 15 degrees for chilling-sensitive produce such as bananas, mangoes and tomatoes. Taken together, perishables are stored between roughly -2 and 16 degrees C.
The ranges 17 to 16 and 20 to 18 degrees are too warm and narrow to cover the commodities stored, and -3 to -5 degrees would freeze and damage fresh fruits and vegetables; that belongs to frozen storage.
