• C. Utilize all the nutrients in a food
• D. Produce products such as acids that inhibit the growth of other organisms

Answer 1

The correct option is D Produce products such as acids that inhibit the growth of other organisms

Fermentation mainly involves the conversion of complex sugar to the simple ones by the bacteria in the absence of oxygen. Food fermentation has five main purposes:

1. Enrichment of the diet through development of a diversity of flavors, aromas, and textures in food substrates.

2. Preservation of substantial amounts of food through lactic acid, alcohol, acetic acid and alkaline fermentations.

3. Biological enrichment of food substrates with protein, essential amino acids, essential fatty acids, and vitamins.

4. Elimination of anti-nutrients.

5. A decrease in cooking time and fuel requirement.
