Latest reviewed evidence
Codex CXS 210-1999, revised in 2024, defines arachis oil as oil from Arachis hypogaea seeds and gives crude-oil identity ranges including relative density 0.909–0.920 at 20 degrees Celsius, saponification value 187–196 milligrams KOH per gram, iodine value 77–107 and unsaponifiable matter no more than 10 grams per kilogram. Codex also lists refined-oil acid value up to 0.6 milligrams KOH per gram and peroxide value up to 10 milliequivalents per kilogram. Its 2025 peanut aflatoxin-prevention code addresses the seed supply chain and representative testing; it is not a certificate for an oil lot. These are identity, process and reference controls—not proof of conformity, allergen status, current availability or a live physical price.

Arachis hypogaea identity comes before a peanut-oil grade
Codex defines arachis, peanut or groundnut oil as oil derived from Arachis hypogaea seeds. Atlas retains species, cultivar or high-oleic claim where evidenced, crop and kernel source, origin and processor rather than assuming that every product called groundnut, arachis or peanut oil has the same fatty-acid profile, refining state or intended use.
Whole peanuts, meal and oil are different products
Peanut kernels are a food and crushing feedstock; expeller or solvent-extracted meal is the protein-rich residue; oil is the lipid product. Shelling, grading, moisture, aflatoxin controls, extraction yield and meal disposition belong to the seed and crush record. Atlas does not transfer a kernel grade, aflatoxin result, meal protein claim or whole-peanut price directly to an oil lot without traceability and a documented mass balance.
Crude, refined, cold-pressed and high-oleic oils stay separate
Crude oil retains extraction and upstream process history and normally requires further refining for many food uses. Refined oil has undergone declared neutralization or physical de-acidification, bleaching, filtration and deodorization steps. Cold-pressed or virgin oil uses a different permitted processing lane, while high-oleic oil is a composition claim requiring cultivar and analytical evidence. Atlas records the exact state, route and claim rather than treating colour, flavour or a marketing name as proof.
Fatty-acid and identity ranges require the tested lot
Iodine value, saponification value, density, refractive index, fatty-acid profile, sterols, tocopherols and arachidic-and-higher fatty acids answer related but different identity questions. Codex notes that arachidic and higher fatty acids in arachis oil should not exceed 48 grams per kilogram. A published range or ceiling is not a result: Atlas keeps sampling plan, laboratory, method, result, uncertainty, test date, package or tank and lot attached.
Aflatoxin controls begin upstream and remain evidence-specific
Codex's revised peanut aflatoxin code covers production, drying, storage, transport, sampling and testing of peanuts, including final drying below 9 percent moisture for kernels as a prevention measure. That guidance helps assess feedstock control but does not prove that a seed lot or finished oil complies. Atlas retains supplier controls, representative kernel results, rejected-lot handling, refining evidence and destination-specific contaminant requirements without implying that refining cures every upstream failure.
Highly refined and less-refined oils need different allergen evidence
U.S. law excludes highly refined oil derived from a major-allergen food from the statutory major-food-allergen definition, while FDA guidance separately addresses highly refined oils and cross-contact. That U.S. labeling boundary is not a universal protein-free claim and does not automatically cover cold-pressed, expelled, gourmet or incompletely refined peanut oils. Atlas records refining state, residual-protein method and result, cross-contact controls, destination law and label basis.
Process contaminants and residues use the exact destination scope
Refined-oil diligence may require results for glycidyl esters, 3-MCPD and its esters, mineral-oil hydrocarbons, pesticide residues, trace metals and other destination-specific contaminants. Current EU rules illustrate that categories, uses, mixtures and transition dates matter. Atlas retains the applicable rule, analytical method, result and lot rather than inferring compliance from the word refined.
An identity range does not establish a delivered peanut-oil price
Named-oil identity, refining status and quality limits do not establish current availability, lot conformity, transaction value or delivered cost. A physical estimate still needs permitted current observations for the exact conventional or high-oleic, crude, refined or cold-pressed product; quality, allergen and contaminant evidence; origin and processor; 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.
