MCQ
An example of food preservative is:
  • Sodium benzoate
  • B
    Adipic Acid
  • C
    Calcium Benzoate
  • D
    Alcohol

Answer

Correct option: A.
Sodium benzoate
An example of food preservative is sodium benzoate $\mathrm{C}_6 \mathrm{H}_5 \mathrm{COONa}..$
It is safely used in limited amounts and is metabolized by conversion to hippuric acid $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CONHCH}_2 \mathrm{COOH},$ which is ultimately excreted into urine.
It is bacteriostatic and fungistatic under acidic conditions. Thus, it prevents the growth of microorganisms in food materials.
