Definitions

  • Ascorbic is a food additive with that serves a variety of functions in foods. It is an excellent antioxidant / stabilizer under certain circumstances. For example, it can be used to prolong the shelf life of vegetables oils, where its beneficial role appears to be in part due to its ability to reduce and thereby recycle oxidized tocopherol intermediates. As oils oxidize, peroxyl- and alkoxyl radical intermediates are formed. Tocopherols, which are natural antioxidants normally present in vegetable oils, donate a phenolic hydrogen atom to the peroxyl and / or alkoxyl radicals, effectively preventing them from carrying on the oxidation radical chain reaction. In the process, tocopherol radicals are produced.
  • Tocopherols are not naturally present in animal fats, but when added are very effective stabilizers. Ascorbic acid / tocopherol combinations in animal fats have proved to be very powerful antioxidant combinations.
