• This invention relates to antioxidants compositions containing an antioxidant synergist mixture. More particularly, this invention relates to antioxidant compositions containing as the antioxidant synergist a mixture of two synergists, e.g., colamine and/or a higher fatty acid salt thereof and a higher fatty acid ester of ascorbic acid.
• higher fatty acid refers to monocarboxylic saturated acids having from 10 to 20 carbon atoms, e.g., capric, lauric, palmitic, stearic, and the like.
• this invention comprehends an antioxidation composition containing (a) an antioxidant, (b) colamine and/ or a higher fatty acid salt thereof and (c) a higher fatty acid ester of ascorbic acid.
• the preferred composition of this invention contains as the antioxidant either aor 'y-tocopherol.
• Colamine can be used as the base or as a salt with a higher fatty acid having 1020 carbon atoms.
• the palmitate and the stearate are the preferred salts.
• the ascorbic acid esters used in accordance with the invention are esters of higher fatty acids having from 10 to 20 carbon atoms, preferably palmitic or stearic acid.
• the amount of ingredients in the antioxidation compositions of this invention are suitable within broad ranges.

• the amount of antioxidation composition utilized in accordance with this invention depends on the requirements of the substrate to be stabilized. Amounts between about 0.01 and about 0.1% by weight are generally sufiicient with oils and fats, and amounts between about 0.5 and about 30% by weight are sufficient in the case of vitamin A preparations.
• this invention contemplates the use of from about 0.01 to about 5% by weight of the antioxidant composition for the stabilization of fats and oils having a content of unsaturated oxidizable fatty acid esters, as well as of essential oils and other aromatic substances.

Examples of such foods are, for example, vegetables, especially in comminuted form, vegetable meals and conversion products thereof, meat commodities and the like.
