What are food grade antioxidants?
Food grade antioxidants are substances added to food products to prevent oxidation, which is the process that causes food to deteriorate and spoil. Antioxidants are used to preserve the freshness, color, flavor, and aroma of food products, by preventing the formation of free radicals that react with oxygen and cause chemical changes in the food.
What are natural antioxidants?
Natural antioxidants are substances derived from natural sources, such as plants, fruits, or herbs. Examples of natural antioxidants include vitamin C, vitamin E, beta-carotene, and polyphenols found in blueberries, grapes, and green tea. Natural antioxidants are usually extracted from these sources using methods such as steam distillation, solvent extraction, or freeze-drying.
What are synthetic antioxidants?
Synthetic antioxidants are chemical compounds that are artificially synthesized to mimic the properties of natural antioxidants. Examples of synthetic antioxidants include butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and tert-butylhydroquinone (TBHQ). Synthetic antioxidants are usually added to food products as a mixture of several chemical compounds.
Which is better: natural or synthetic antioxidants?
The answer to this question is not straightforward and depends on several factors. Natural antioxidants are preferred by many people because they are seen as more “natural” and less harmful to human health than synthetic antioxidants. However, natural antioxidants are not always more effective than synthetic antioxidants at preventing oxidation in food products.
Synthetic antioxidants are often more stable and have a longer shelf life than natural antioxidants. They are also less expensive to produce and are therefore used more frequently in food products. Studies have shown that some synthetic antioxidants, such as BHT and TBHQ, are safe for human consumption when used in small amounts. However, some synthetic antioxidants, such as BHA, have been linked to health concerns such as cancer and hormonal imbalance when consumed in large amounts.
In summary, the choice between natural and synthetic antioxidants depends on the specific food product and the desired outcome. Natural antioxidants are generally preferred for their perceived safety and “natural” status, while synthetic antioxidants are more stable and cost-effective. It is important to use both types of antioxidants responsibly and in accordance with regulations set by food safety authorities.
