Method of preparing food using rice oil
The present invention relates to methods of preparing food using rice oil which has increased levels of oleic acid and decreased palmitic and linoleic acids, for increased stability to oxidation and health benefits.
1. A method of preparing food, the method comprising cooking an edible substance in rice oil from rice grain having a fatty acid composition comprising greater than 60% w/w oleic acid, less than 15% w/w palmitic acid and less than 25% w/w linoleic acid, wherein the rice oil has not been exposed to a procedure which alters the ratio of oleic acid to linoleic acid, palmitic acid to oleic acid, and/or palmitic acid to linoleic acid when compared to the ratio in the rice grain.
2. The method of claim 1 , wherein in the rice oil the weight ratio of oleic acid to linoleic acid is greater than 3.0:1.
3. The method of claim 1 , wherein the rice oil has a fatty acid composition comprising greater than 60% oleic acid, less than 12% palmitic acid, and/or less than 15% linoleic acid.
4. The method of claim 1 , wherein the rice oil further comprises γ-oryzanol.
5. The method of claim 1 , wherein the rice oil is substantially purified.
6. The method of claim 5 , wherein the substantially purified rice oil is at least 75% free from other components with which it is naturally associated.
7. The method of claim 6 , wherein the substantially purified rice oil is at least 90% free from other components with which it is naturally associated.
