(a) True

(b) False

I had been asked this question in a national level competition.

I need to ask this question from Principles of Food Storage Stability in section Principles of Semi-Moist Foods, Principles of Food Preservation by Fermentation, Principles of Food Pickling and Curing and Principles of Food Storage Stability of Food Engineering

Answer 1

Correct answer is (a) True

For explanation: With respect to frozen products, a sample held for 1 week at -3 deg C will be indistinguishable from a sample of the same product at -17 deg C for a year. Every 5 degC that the temperature is increased, the speed of quality loss increases by 2-2.5 times.
