What is rice bran oil?

Sometimes called rice bran extract, rice bran oil is exactly what it sounds like - oil extracted from the germ and inner husk of rice kernels.  There is very little bran in rice and only 20% of that is oil, so it requires a ton of rice to get a little oil.  Fortunately the process of milling white rice removes the bran as a byproduct and this excess bran where the oil is extracted from so tons of food are not wasted to make rice bran oil (unlike say corn oil or olive oil where the primary item gained from processing is the oil. Rice Grain Anatomy

Qualities of Rice Bran Oil

Oil extracted from rice bran as a number of  is interesting qualities:

  • Very high smoke point of 490 °F (254 °C) making it useful for high-temperature cooking methods such as stir frying and deep-frying.
  • Mild flavor that does not overpower the natural taste of the food it is mixed with
  • Used as a cooking oil in several Asian countries, including Japan and China.
  • When consumed at room temperature or cooler, oil extracted from rice bran is rich in vitamin E, gamma-oryzanol (an antioxidant that is used for many alternative herbal therapies, which may help prevent heart attacks), and phytosterols (compounds believed to help lower cholesterol absorption)

Suggested Health Benefits to Rice Bran Oil: Cholesterol Reduction

Mohammad Minhajuddin published the results of animal studies in the May 2005 "Journal of Food and Chemical Toxicology" that showed a 42-percent decrease in total cholesterol with a 62-percent drop in low-density lipoproteins, or LDL cholesterol, when researchers supplemented test subjects' diets with fractionated vitamin E obtained from rice bran oil.  

M. Most also published results  in the "American Journal of Clinical Nutrition" of a small human study conducted with 26 participants in the January 2005. These test subjects saw a 7-percent

decrease in LDL cholesterol with no change in total cholesterol during a 10-week study. using rice bran oil.

Other scientific studies have shown that the antioxidant stability in rice bran oil remains almost constant even when heated at frying temperatures. In some studies, the oxidative stability of rice bran oil was found to be equivalent to or better than soybean, corn canola, cottonseed, and safflower oil in a model system that simulated deep frying conditions.The study of thermal degradation and antioxidant stability in the oil was carried out by heating the oil to the frying temperature up to 250°C for 0.5, 1, 1.5, 2 hours. The density of rice bran oil is found to be constant throughout the time of heating illustrates there is no molecular changes due to antioxidant activity in the oil.

Because rice bran oil is a completely plant based oil is is naturally cholesterol free like all plant based oils.  When used in place of butter, lard or animal shortening it directly reduces cholesterol intake.

Rice bran oil for Menopause

Studies show that the rice bran extract in its natural powder form is not easily absorbed by the human body but that when converted to oil absorbtion is much better. 

Nutracutical Benefits

Rice bran is the only food that contains powerful anti-oxidant Gamma-Oryzanol in meaningful amounts.  Gamma-Oryzanol helps convert fat to muscle, good for fat races horses and fat humans.
