rice bran absolute

Rice bran absolute is an aromatic natural extract obtained from the bran of rice (Oryza sativa). It appears as a viscous, oily liquid notable for its distinctive grain and toasted aromas and flavors, often described as creamy, spicy, woody, and custard-like. Known also as oryza sativa absolute, bran of rice absolute, and rice bran oil, it falls within the category of natural absolutes widely utilized in flavor and fragrance industries. The compound is sourced through solvent extraction of rice bran, which is the outer layer removed during rice milling. Its unique sensory profile attributes to its usage in complex note formulations and natural product blends. The chemical and sensory data align with records in databases such as PubChem.

Rice bran absolute is naturally derived from rice, a staple cereal crop cultivated worldwide. Because of its characteristic grainy and toasted aroma notes, this absolute is employed in flavor and fragrance applications where a natural, warm, and creamy grain nuance is desired. It blends well with honey and ylang ylang notes, enhancing complexity in formulations. Regulatory frameworks, such as IFRA (Global), provide usage recommendations for rice bran absolute, where concentrations up to 10% are generally accepted in fragrance concentrates. Its natural origin and favorable sensory characteristics support its continued utility in fine fragrance, natural perfumes, and flavor enhancement within food-related products.

Rice bran absolute exhibits solubility in both alcohol and water, with an estimated water solubility of approximately 8.34 × 10^-20 mg/L at 25 °C, indicating extremely low water solubility despite positive solubility classification. This suggests that alcohol solvents are primarily used for formulation and extraction purposes. The viscous, oily nature supports its easy incorporation into oil-based and alcohol-based matrices. The distinctive grain and toasted sensory attributes arise from complex mixtures of volatile organic compounds present in the absolute, making it a valuable component for imparting natural warm and nutty notes. Its physicochemical profile facilitates stable blending in cosmetic and flavor applications without significant reactivity or notable hazard concerns under standard conditions.
