Abstract
The invention is directed to a method and composition which inhibits the oxidation of omega-3 and omega-6 polyunsaturated lipids in an aqueous emulsion. This invention is especially directed to a method and composition which inhibits the oxidation of long chain omega-3 polyunsaturated lipids in an aqueous emulsion. When soy protein, and in particular, soy protein isolates, are blended with omega-3 and/or omega-6 polyunsaturated lipids, the rate of oxidation of the omega-3 and/or omega-6 lipids is reduced and the shelf life of such lipids is extended.
Claims20
A method to reduce the rate of oxidation of omega-3 or omega-6 polyunsaturated lipids in an aqueous emulsion, the method comprising blending soy protein into the emulsion in an amount effective for slowing the rate of oxidative rancidity of the omega-3 or omega-6 polyunsaturated lipid in the emulsion.
A method to reduce the rate of oxidation of long chain omega-3 polyunsaturated lipids in an aqueous emulsion, the method comprising blending soy protein into the emulsion in an amount effective for reducing the oxidation of the omega-3 polyunsaturated lipids by at least 8 times as compared to an emulsion stored for about the same time and at about the same temperature with the same amount of omega-3 lipids which emulsion does not have an oxidation stabilizer.
An aqueous emulsion comprising
- an omega-3 or omega-6 polyunsaturated lipid;
- and
- at least about 0.5 percent soy protein, the amount of soy protein in the emulsion effective for reducing the oxidation of the omega-3 or omega-6 polyunsaturated lipids by at least 8 times as compared to a control emulsion stored for about the same time and at about the same temperature with the same amount of omega-3 or omega-6 lipids, wherein the control emulsion does not have an oxidation stabilizer.
