Rice bran oil — komeyu — is the oil extracted from the pericarp and germ fractions of rice (rice bran, the byproduct of polishing). It is one of the few major culinary oils produced domestically in Japan at scale, and it is valued both for its high smoke point and for its natural gamma-oryzanol content. The same raw material also produces a cosmetic-grade oil used in skincare formulations.

Ingredient profile
Rice bran oil is extracted from rice bran by solvent extraction (for most food-grade volumes) or expeller pressing. The fatty acid profile is roughly balanced between saturated and mono/poly-unsaturated fats: oleic acid 38–48 percent, linoleic acid 30–35 percent, palmitic acid 15–20 percent.
The oil is also a natural source of gamma-oryzanol — a mixture of ferulic acid esters of sterols and triterpene alcohols — which drives some of its supplement and cosmetic positioning.
OEM applications
Rice bran oil is one of Japan's standard deep-frying and all-purpose cooking oils, valued for a clean flavor and a high smoke point. It is widely used for tempura, karaage, and other deep-fried dishes.
In cosmetics, Oryza Sativa Bran Oil is used as an emollient, often alongside rice-derived extracts, to reinforce a rice-ingredient brand narrative.
Gamma-oryzanol is sometimes isolated and sold as a separate supplement or cosmetic ingredient.

FAQ for OEM buyers
Q. What is gamma-oryzanol and why is it relevant to OEM positioning?
Gamma-oryzanol is a mixture of ferulic acid esters naturally present in rice bran oil (typically 0.1-2% in refined oil, higher in unrefined). It is the basis for antioxidant and cholesterol-related positioning in supplements, and is also approved as a quasi-drug active in Japan for certain skincare claims.

Q. What is the smoke point of refined rice bran oil and why does it matter for foodservice OEM?
Refined rice bran oil has a smoke point of approximately 230°C, making it well-suited for tempura and karaage frying applications. This thermal stability and clean flavor make it a default choice for Japanese foodservice and prepared-food OEM frying programs.
