It is a substance that can help capture and neutralize free radicals, thus relieving the harm of free radicals to human body. Free radical is a molecule with one or more unpaired electrons, and it is a conventional product of metabolic process.
Antioxidants can eliminate the reaction between free radicals and other molecules, which is called oxidation. The human body will also produce some antioxidants to keep the balance of the body. Then, with the growth of age and the influence of the environment, air pollution and smoking will increase the number of free radicals in the body, thus destroying the natural balance of the body.
Introduction of action mechanism:
1. Reduce the oxygen content in and around food through the reduction reaction of antioxidants. Some antioxidants, such as ascorbic acid and isoascorbic acid, are easily oxidized, which can make the oxygen in food react with them first, thus avoiding the oxidation of oil.
2. Hydrogen atoms released by antioxidants combine with peroxides generated by the automatic oxidation reaction of oils and fats, thus interrupting the chain reaction and preventing the oxidation process from continuing.
3. By destroying and weakening the activity of oxidase, it can not catalyze the oxidation reaction.
4. Blocking substances that can catalyze and cause oxidation reaction, such as complex metal ions that can catalyze oxidation reaction [1].
