During AFP/sterilisation, which vitamins are destroyed?

Explanation:
Heat-sensitive vitamins are most affected by high-temperature sterilisation. Vitamin C (ascorbic acid) is very unstable when exposed to heat and oxygen, so it degrades readily during processing. Vitamin B1 (thiamine) also loses activity with heat, especially under prolonged heating or alkaline conditions used in some sterilisation steps. In contrast, vitamin A (a fat-soluble vitamin) is relatively stable to heat, and riboflavin (B2) is more resistant to heat than vitamins C and B1, so these two are not significantly destroyed under typical AFP/sterilisation conditions. Therefore, the vitamins most affected are C and B1, while A and B2 remain largely intact.
