Rice Bran Oil as a Healthy Cooking Medium

Rice Bran Oil as a Healthy Cooking Medium

Rice bran oil indeed has the most desirable fat composition,better frying stability and offers unique health benefits due to the presence of phytosterols and oryzanols.


Like rice bran, groundnut oil too has an ideal fat composition.

Approximate fatty acid composition of dietary fats and oils consumed in India (% of total fatty acids)-

• Ideal Fatty Acid Composition of Oils

According to experts "The ratio of SFA: MUFA: PUFA of any oil is very important". In accordance to the latest recommendations by National Institute of Nutrition (NIN) and Indian Council of Medical Research (ICMR) the ideal fatty acid composition of a oil should be 27-33% : 33-40% : 27-33%. And the fatty acid composition of Rice bran oil comes closest to these recommendations with the percentages at 24: 42: 34." Rice Bran Oil indeed has the most ideal fat composition, better frying stability and offers unique health benefits due to phytosterols and oryzanols present in it. The other oil which has an ideal fat composition is groundnut oil.

• Smoking Point

The smoking point of a fat is a desirable quality for a cooking medium. Oil very high in PUFA has a low smoking point and oil high in MUFA has a relatively higher smoking point.

The smoke point of various eating oils is important to note because when oils are heated beyond their smoking point they develop free radicals which contribute to risk of cancer. A fat is no longer fit for consumption after it has exceeded its smoke point as it begins to break down. Oils with low smoking point cannot be used for high temperature cooking / frying. Though olive oil is one of the healthiest oil for cooking, by using extra virgin olive oil for frying one is doing more harm than good.

• Non glyceride components of dietary fats and oils

Besides fats, vegetable oils contain non glycerides which have specific health significance-

Nonglyceride components	Oil	Biological and health function
Plant sterols Vitamin A, D, K	All vegetable oils Ghee/butter	Hypocholesterolemic Vitamin
Tocopherols	All vegetable oils	Vitamin, Antioxidant
Tocotrienols	Palm oil, Rice bran oil	Vitamin, Antioxidant
Carotenes	Red Palm oil	Provitamin, Antioxidant
Oryzanols	Rice bran oil	Hypocholesterolemic Antioxidant
Sesamin	Sesame	Hypocholesterolemic Anti-inflammatory
Sesamolin, Sesamol	Sesame	Antioxidant
