Question

Which of the following is the process of anaerobic degradation of proteinaceous materials?

(a) Respiration

(b) Fermentation

(c) Putrefaction

(d) All of the mentioned

I got this question in an internship interview.

The question is from Principles of Food Preservation by Fermentation-1 in chapter 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 option is (c) Putrefaction

To explain I would say: Putrefaction is the process of anaerobic degradation of proteinaceous materials. Fermentation is the process of anaerobic oxidation of carbohydrates. Respiration is the process where carbohydrates are converted aerobically to carbon dioxide and water with the release of large amounts of energy.
