Rice bran oil is oil derived from the bran layer removed when Oryza sativa rice is milled. Rice bran, crude oil, degummed or neutralized oil, physically or chemically refined oil, winterized oil, edible finished oil, blends and industrial derivatives are not interchangeable products. Comparable records preserve rice species and bran source, stabilization history, extraction method and solvent, crude or refined state, deacidification, bleaching, dewaxing or winterization and deodorization history, fatty-acid and sterol identity, density, refractive index, iodine and saponification values, free fatty acids or acid value, peroxide value, moisture and volatile matter, unsaponifiable matter, oryzanol result and method, wax, residual solvent, contaminants and residues, package or tank and lot, origin, intended use, quantity, currency, Incoterm, destination, delivery window and information vintage.
Codex CXS 210-1999, revised in 2024, defines rice bran oil and provides identity and quality references including relative density 0.910–0.929, iodine value 90–115, crude-oil gamma oryzanols 0.9–2.1 percent, refined rice-bran-oil free fatty acids up to 0.3 percent as oleic acid and refined-oil peroxide value up to 10 milliequivalents of active oxygen per kilogram. India's FSSAI standard separately requires rice bran oil sold for human consumption in India to be refined and specifies moisture and volatile matter no more than 0.1 percent, acid value no more than 0.5 milligrams KOH per gram and oryzanol at least 1.0 percent. These are standard-specific reference values—not proof of an offered lot's conformity, destination authorization, availability, health effect or current physical price.
Codex and FSSAI identify rice bran oil through the bran layer of Oryza sativa grain removed during milling. Fresh bran, stabilized bran, de-oiled bran and oil are separate materials with different mass balances, storage risks and evidence. Atlas retains mill, rice source, bran stabilization time and method, extraction yield and chain of custody rather than transferring a rice or bran specification directly to the oil.
Crude rice bran oil retains extraction history and typically contains more free fatty acids, wax and unsaponifiable matter than a finished edible oil. Chemical refining may include alkali neutralization, bleaching and steam deodorization; physical refining uses a different deacidification route. Dewaxing or winterization addresses wax-related clarity. Atlas records each process state and does not infer food-grade or cold-stability status from the generic product name.
Relative density, refractive index, saponification value, iodine value, unsaponifiable matter, fatty-acid profile, sterols and tocopherols answer related but different identity questions. Codex lists ranges for rice bran oil, but a published range is not a tested result. Atlas retains the cited standard edition, method, measurement temperature, sampling plan, laboratory, uncertainty, result, test date, tank or package and lot.
Codex provides a gamma-oryzanol range for crude rice bran oil, while FSSAI specifies an oryzanol minimum in its India-specific finished-oil standard. FSSAI publishes both a spectrophotometric total-oryzanol method and an HPLC method for gamma-oryzanol label claims. Atlas keeps crude or refined state, analyte definition, method, calibration, result and lot together and does not convert an oryzanol number into a nutritional, therapeutic or disease claim.
Rice bran oil naturally presents wax-management questions. ISO/TR 23647 describes gas-chromatographic wax measurement across crude, degummed, neutralized, winterized and fully refined vegetable oils, including rice bran oil. A wax result, visual clarity result and dewaxing or winterization record are distinct evidence. Atlas retains test temperature, method, processing stage, storage condition and lot rather than assuming clear oil is compositionally equivalent.
Solvent-extracted material requires a declared solvent and destination-specific residual-solvent evidence. FSSAI's India standard limits hexane in refined solvent-extracted rice bran oil to 5 parts per million and requires a flash point of at least 250 degrees Celsius; Codex provides acid or free-fatty-acid and peroxide-value references. Atlas retains extraction route, refining records, method, result, limit of quantification and lot instead of treating the word refined as a certificate.
Commercial diligence may require pesticide-residue, trace-metal, mineral-oil-hydrocarbon, glycidyl-ester, 3-MCPD-ester and other destination-specific results. A blended edible oil is not a pure rice bran oil lot, and composition, percentage, label and analytical evidence must stay explicit. Atlas records intended use, destination category, applicable rule, ingredients, laboratory results, package and lot without inferring compliance from origin or processor reputation.
Identity ranges, refining requirements and analytical methods do not establish current availability, lot conformity, transaction value or delivered cost. A physical estimate still needs permitted current observations for the exact crude, refined, winterized or blended product; process, quality and contaminant evidence; origin and processor; package or tank and lot; intended use; quantity, currency, Incoterm, load and destination points, delivery window, freight, duties and information vintage. Atlas withholds a physical estimate when those observations or usage rights are missing.
No. Refining changes free fatty acids, colour, odour, wax, contaminants and intended-use evidence. The process route and actual lot results must be retained.
No. Oryzanol is a measured composition or identity marker. A result does not establish a clinical, therapeutic or disease claim.
No. The standards overlap but differ in jurisdiction, parameters and legal use. Each claim requires the applicable standard, current edition, method, sampling and lot results.
No. Extraction and refining records plus a suitable lot-specific test are needed where the destination rule or buyer specification requires residual-solvent evidence.
