Step 1: Understanding the Concept:
Antioxidants are added to lipid-rich foods to prevent autoxidation of unsaturated fatty acids, thereby preventing off-flavors and extending shelf life.
Step 2: Detailed Explanation:
- Ghee (clarified butterfat) is highly susceptible to oxidative rancidity during storage, especially when exposed to light, air, and trace metals.
- To prevent oxidation, the addition of synthetic antioxidants like Butylated Hydroxyanisole (BHA) is permitted.
- Under the Food Safety and Standards (Food Products Standards and Food Additives) Regulations, the maximum level of permitted synthetic antioxidants (such as BHA) in ghee is 0.02% by weight of the product (which is equivalent to 200 ppm).
Step 3: Final Answer
The maximum level of permitted antioxidant in ghee is 0.02% by weight of the product.
