Hint:

Note: Always check the label for permitted preservatives and their concentration.

Answer 1

Class II preservatives are synthetic chemical preservatives used to extend the shelf life of processed fruits and vegetables.
In India, as per the Food Safety and Standards Authority of India (FSSAI) regulations, commonly permitted Class II chemical preservatives include three main chemicals:
These are Sulphur dioxide, Benzoic acid, and Sorbic acid.
Sulphur dioxide is mainly used in fruit juices, jams, and dried fruits to prevent browning and spoilage.
Benzoic acid and its salts like sodium benzoate help inhibit the growth of yeasts and molds in fruit syrups and pickles.
Sorbic acid is also used as an effective preservative in fruit pulps and juices.
These chemical preservatives must be used within the prescribed limits to ensure food safety and consumer health.
