Latest reviewed evidence
Codex CXS 210-1999 defines sesame seed oil as oil from Sesamum indicum seeds and gives crude-oil identity references including relative density 0.915–0.924 at 20 degrees Celsius, saponification value 186–195 milligrams KOH per gram, iodine value 104–120 and unsaponifiable matter no more than 20 grams per kilogram. Its supplementary quality references distinguish refined from cold-pressed or virgin oils and state that the Baudouin test should be positive for sesame seed oil. FDA identifies sesame as a major food allergen in the United States, while EU Regulation 1169/2011 lists sesame seeds and products thereof; the exact labeling and highly refined-oil treatment remains destination- and process-specific. Codex bulk-oil guidance addresses oxidation, contamination, tanks, cleaning and previous cargoes. These are identity, process, labeling and custody references—not proof of an offered lot's conformity, authenticity, availability or live delivered price.

Sesamum indicum identity comes before a sesame-oil grade
Codex defines sesame seed oil and its gingelly, benne, ben, till and tillie synonyms as oil derived from Sesamum indicum seed. Atlas retains the declared species, cultivar or composition claim where material, seed crop and origin, processor and tested oil identity rather than treating a trade synonym, colour, aroma or label as proof that different lots are equivalent.
Sesame seed, tahini and oil are different product stages
Natural or hulled sesame seed is the agricultural feedstock; tahini is a ground-seed product; oil is the separated lipid fraction; and press cake or meal is a distinct coproduct. Seed purity, moisture, microbiology, residues and allergen controls remain upstream evidence. Atlas keeps seed inputs, cleaning or roasting, extraction yield, mass balance and custody attached and does not transfer a seed grade, tahini result or seed price directly to an oil lot.
Cold-pressed, virgin, toasted, crude and refined oils stay separate
Codex defines virgin oil through mechanical procedures with heat allowed and cold-pressed oil through mechanical procedures without applied heat, with limited purification steps. Commercial toasted oil adds a documented roasting stage before extraction. Crude oil can retain extraction and upstream process history; refined oil may undergo neutralization or physical de-acidification, bleaching, filtration and deodorization. Atlas records the exact process, temperature history, solvent where used, refining state and intended use instead of inferring them from dark colour, flavour or a generic premium claim.
Seed origin, extraction origin and refining origin remain distinct
Sesame can be grown in one country, cleaned or toasted in another, pressed or solvent-extracted elsewhere and refined, blended or bottled at a final location. Atlas preserves seed crop and production origin, processing facilities and dates, lot splits and merges, mass balance, certificates and custody events. The export or bottling country does not silently replace the agricultural origin of the seed or the actual extraction and refining record.
Composition and authenticity require a tested lot
Relative density, refractive index, saponification value, iodine value, unsaponifiable matter, fatty-acid and sterol profiles and the supplementary Baudouin test answer related but different identity questions. A Codex range or positive reference test is not a supplier result and one marker alone does not exclude dilution or blending. Atlas retains the standard edition, sampling plan, method, laboratory, result, uncertainty, test date, package or tank and exact lot.
Allergen and cross-contact evidence follows process and destination
FDA identifies sesame as a major food allergen in the United States and EU Regulation 1169/2011 lists sesame seeds and products thereof. The treatment of a particular oil can depend on refining state, residual protein, cross-contact, intended use, destination law and labeling basis. Atlas does not turn the word refined into a universal allergen-free claim; it retains process records, suitable residual-protein evidence where relevant, shared-line controls, label basis and the exact destination requirement.
Oxidation, process contaminants and custody remain lot specific
Acid and peroxide values, moisture and volatile matter, insoluble impurities, trace metals, pesticide residues, polycyclic aromatic hydrocarbons, 3-MCPD and glycidyl esters can depend on feedstock, roasting, extraction, refining, storage and destination category. Codex bulk-oil guidance also keeps tank material, cleanliness, previous cargo, temperature, air exposure and segregation in scope. Atlas records method, result, rule, package or tank, seal, cleaning, previous cargo and lot rather than inferring conformity from processor reputation.
An identity standard does not establish a delivered sesame-oil price
Named-oil identity, allergen rules, composition ranges and storage guidance do not establish current availability, lot conformity, transaction value or delivered cost. A physical estimate still needs permitted current observations for the exact crude, virgin, cold-pressed, toasted, refined or blended product; seed and processing origins; process, quality, allergen and contaminant evidence; package or tank and lot; 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.
