Some products are easily affected by certain factors during use, which can lead to malfunction or degradation. Antioxidants share this characteristic—when the product is being used, transported, or stored, external environmental changes may cause it to lose effectiveness under specific conditions, resulting in a partial or complete loss of performance. Among these influencing factors is photo-thermal oxidation, which happens to be the "arch-nemesis" of many products. Therefore, to maintain their antioxidant properties, it’s crucial to shield them from the detrimental effects of light, heat, and oxygen.
1. While using antioxidants, it’s also important to be aware of certain factors that can accelerate fat oxidation, such as light—especially ultraviolet radiation—which readily triggers lipid oxidation. To mitigate this, opt for packaging materials that effectively block out light. Additionally, high temperatures during processing and storage not only promote the oxidation of fats in food but also increase the volatility of antioxidant compounds. Transition metal elements, particularly those with appropriate redox potentials—such as trivalent or polyvalent transition metals—exert a strong catalytic effect on fat oxidation. Therefore, it’s crucial to minimize the contamination of these ions as much as possible. However, due to natural presence in soil or contamination from processing equipment and containers, food products often inadvertently contain trace amounts of these ions.
2. The presence of large amounts of oxygen will accelerate oxidation. Measures such as nitrogen-flushing packaging or vacuum-sealed packaging can be employed, and oxygen absorbers—or deoxidizers—can also be used. Otherwise, if food is allowed to come into direct contact with oxygen, even substantial additions of this product may fail to achieve the desired results.
This clearly demonstrates that antioxidants can only be effectively used and stored under the right environmental conditions. In our daily usage, we must find ways to prevent the product from oxidizing, ensuring that its antioxidant capabilities remain intact—after all, one of the key reasons we choose it in the first place is its strong ability to combat oxidation. Therefore, to extend the product's lifespan, it’s crucial to create favorable conditions for it, carefully avoiding the damaging effects of light, heat, and oxygen.
