Plastic tarpaulin needs to pay attention to the dosage of antioxidants added in the production process. The amount of this amount reflects the quality of the product, so we need to pay special attention. 1. Synergistic effect of antioxidants: When two or more antioxidants are used in combination, the antioxidant effect is usually greater than the sum of single use. This phenomenon is called synergy of antioxidants. It is generally believed that this is because different antioxidants can each terminate the chain reaction of lipid oxidation at different stages. Another synergy is the combination of primary antioxidants with other antioxidants and metal ion chelators. 2. Appropriate dosage: Unlike preservatives, the amount of antioxidants added is not always positively correlated with the antioxidant effect. Exceeding a certain concentration can not only improve the antioxidant effect, but also promote oxidation. 3. When to add: In the mechanism of action of antioxidants, it can be seen that antioxidants can interfere with lipid oxidation and delay the time when food begins to deteriorate, and since the decomposition results cannot be changed, antioxidants should be added as soon as possible.
