Abstract
Stabilized oils including an edible oil and an antioxidant composition comprising α-lipoic acid and least one of ascorbic acid, ascorbyl palmitate, green tea extract, lecithin, and rosemary extract or at least one of 1,2,4-benzenetriol, carnosic acid, dihydromyricetin, dihydrorobinetin, epigallocatechin, gallic acid, 3-hydroxytyrosol, myricetin, and nepodin, and methods of preparing such stabilized edible oils. The stabilized oils may have an Oxidative Stability Index (“OSI”) at 110° C. of at least 30 hours.
Claims29
A stabilized oil comprising:
- an edible oil;
- and
- an antioxidant composition,
- wherein the antioxidant composition comprises:
- α-lipoic acid;
- at least one of 1,2,4-benzenetriol, carnosic acid, dihydromyricetin, dihydrorobinetin, epigallocatechin, gallic acid, myricetin, and nepodin;
- and
- no more than 1600 ppm of phospholipid based on a total amount of the stabilized oil, wherein the stabilized oil has an α-lipoic acid concentration of from about 100 ppm to about 2,000 ppm.
A method for preparing a stabilized oil, the method comprising:
- providing an edible oil;
- and
- adding an antioxidant composition to the edible oil to provide a stabilized oil, the antioxidant composition comprising:
- α-lipoic acid;
- at least one of 1,2,4-benzenetriol, carnosic acid, dihydromyricetin, dihydrorobinetin, epigallocatechin, gallic acid, myricetin, and nepodin;
- and
- no more than 1600 ppm of phospholipid based on a total amount of the stabilized oil, wherein the stabilized oil has an α-lipoic acid concentration of from about 100 ppm to about 2,000 ppm.
A stabilized oil comprising:
- an edible oil;
- and
- an antioxidant composition,
- wherein the antioxidant composition comprises:
- α-lipoic acid;
- at least one of 1,2,4-benzenetriol, carnosic acid, dihydromyricetin, dihydrorobinetin, epigallocatechin, gallic acid, myricetin, and nepodin;
- and
- no more than 1600 ppm of phospholipid based on a total amount of the stabilized oil, wherein the stabilized oil has an α-lipoic acid concentration of from about 100 ppm to about 2,000 ppm, and
- wherein the stabilized oil has at least a synergistic amount of the at least one of 1,2,4-benzenetriol, carnosic acid, dihydromyricetin, dihydrorobinetin, epigallocatechin, gallic acid, myricetin, and nepodin.
