Rice oil is produced by processing the gem of the rice and is an oil with an acidity of less than 0.50%.

Advantages :

• lowers the rate of harmful LDL cholesterol
• contributes to the absorption and elimination of cholesterol
• helps reduce the level of triglycerides responsible for atherosclerosis risk

In heating processes, rice oil loses some of the potential of the antioxidants tocopherol and gamma oryzanol around 70° and the loss is most pronounced around 90° (1).

An interesting application of rice oil, in particular rice bran oil, concerns its use as a nanoemulsion in drug transport systems (2).

Rice bran oil appears as a yellowish oily liquid.

It is obtained by the leaching method or squeezing process or a by-product of rice bran and contains 43％ monounsaturated fatty acids, 35％ polyunsaturated fatty acids and 22％ saturated fatty acids, it has a high smoke point which facilitates light frying or intensive frying of food.

In cosmetics, rice bran oil can replace carnauba wax, it acts as a humectant and moisturiser for the skin and its inclusion adds a natural fragrance to products.
