However, because the ingredients such as carnosol, rosemary phenol and rosemary dialdehyde in rosemary have strong antioxidant functions, they can provide hydrogen, Neutralize these free radicals, thereby preventing the oxidation reaction.

Wang Wenzhong and Wang Ying’s experimental studies have shown that rosemary antioxidants have strong antioxidant capacity in soybean oil, peanut oil, palm oil, rapeseed oil and lard. Especially in soybean oil and lard, their antioxidant capacity is The synthetic antioxidant BHA is 2-4 times.

2.Application in meat products

Meat and poultry products are pre-cooked, minced, sliced ​​and other processes, which can easily cause oxidative decay. Studies have shown that when meat products are processed, a large number of muscle tissue cells will rupture, thereby releasing combined iron and enzymes.
