Lactose is not one interchangeable powder. Food-grade lactose may be anhydrous, contain one molecule of crystallisation water, or be a mixture of both forms, while pharmaceutical, infant-formula and other controlled uses need their own applicable specifications. Atlas fixes grade and intended use, hydrate form, source stream, purity basis, moisture or loss on drying, ash, pH, microbiological and contaminant evidence, package, lot, origin and delivery terms before comparing offers.
Codex CXS 212-1999 defines food lactose as a natural milk constituent normally obtained from whey with at least 99.0 percent anhydrous lactose on a dry basis. Its voluntary commercial annex lists sulphated ash no more than 0.3 percent dry basis, loss on drying no more than 6.0 percent and pH 4.5 to 7.0. CXS 234-1999 names methods for anhydrous lactose, loss on drying, pH and sulphated ash. These are standard boundaries and methods, not lot results, current supply or a live physical price.
Codex describes lactose as anhydrous, containing one molecule of water of crystallisation, or a mixture of both forms. The hydrate form changes the relationship between as-is mass and anhydrous-lactose content. Atlas therefore retains the declared form, assay basis, water or loss-on-drying result and method rather than treating every lactose powder or assay percentage as directly comparable.
CXS 212-1999 applies to sugars intended for human consumption without further processing, including ingredients in food. It does not establish pharmaceutical-compendial conformance, infant-formula suitability or a buyer's functional grade. Atlas records intended use, governing specification and edition, regulatory market, allergen and milk-origin declaration, manufacturing and quality certifications, microbiological and contaminant criteria, and claim disposition. A food-standard result cannot be relabelled as pharmaceutical grade.
Codex CXS 234 identifies ICUMSA titrimetry for anhydrous lactose, USP General Chapter 731 gravimetry at 120 degrees Celsius for 16 hours for loss on drying, ICUMSA potentiometry for pH and ISO 5809 for sulphated ash. Atlas keeps the analyte, method and edition, basis, sample and lot, laboratory, result, uncertainty or reporting limit where relevant, certificate and test date together. A certificate value detached from method and lot does not verify another shipment.
Codex identity and composition limits do not establish mesh or particle-size distribution, flow, colour, solubility, microbiological status, source-plant approval, present availability, transaction value, freight or destination cost for a current lot. A delivered comparison still needs permitted current observations for the exact grade, hydrate form and use, specification and test evidence, package, origin, quantity, currency, Incoterm, destination, delivery window, route costs and information vintage. Atlas withholds a physical estimate when those observations or usage rights are missing.
No. Codex allows anhydrous lactose, lactose with one molecule of crystallisation water, or a mixture, but the form and analytical basis must remain attached to the lot.
Not under the Codex identity statement. The 99.0-percent minimum is anhydrous lactose content on a dry basis. Atlas preserves both the assay basis and the water or loss-on-drying result.
No. CXS 212-1999 covers food use. Pharmaceutical or another controlled use requires the applicable separate specification, edition, test methods and lot certificate.
Grade and intended use, anhydrous, monohydrate or mixed form, source stream, anhydrous assay and basis, water or loss on drying, ash, pH, particle size and functional fields where specified, microbiological and contaminant evidence, allergen and origin declaration, method, package and lot, quantity, currency, Incoterm, destination, delivery window and evidence date.
Figures retain their source, period and review date. Corroboration is not promoted to primary evidence.
