Latest reviewed evidence

An FDA-hosted supplier certificate for a named non-GMO corn-starch product lists a 14 percent moisture ceiling, pH 4.0 to 7.0, 0.15 percent ash ceiling, 30 parts-per-million sulfur-dioxide ceiling and 98 percent starch-value floor, but the displayed lot results are redacted. These are one supplier's specification fields in a dated attachment, not FDA-adopted universal limits, proof of that lot's results, current market supply or price.

Maize source and starch identity come before the generic name

FDA's compliance policy states that starch made from corn may be labelled starch or cornstarch, while starches from potato, wheat, tapioca or another source should identify that source. FDA's ingredient inventory separately records cornstarch and starch, maize under its corn-starch identifier. Atlas retains maize source, botanical and variety evidence, facility, batch and chain of custody rather than accepting starch as a source-neutral identity.

Native, pregelatinized, high-amylose and modified starches are separate products

The USDA National Organic Program technical report defines native cornstarch as wet-milled starch that is dried without further modification and places chemically modified derivatives outside that report's scope. FDA's policy distinguishes food starch-modified and its required name, while FDA GRN 615 concerns a specific high-amylose cornstarch and intended use, not ordinary native starch. Atlas records raw-material variety, amylose basis, gelatinization or other physical treatment, enzyme or chemical modification, reagents and residuals, and intended use before comparing an observation.

Starch, meal, grits, protein feed, germ and sweeteners stay separate

The EU Catalogue of Feed Materials identifies maize starch as technically pure starch obtained from maize and separately defines pregelatinized maize starch, maize protein or gluten, maize protein feed, germ, meal, grits, steep liquor and other wet-milling co-products. Corn syrup and dextrose require further conversion. Product mass, composition and value cannot be transferred among these fractions without a documented process, recovery yield and analytical basis.

A specification field is not a tested result or delivered price

The FDA-hosted supplier certificate makes the distinction visible: moisture, pH, ash, sulfur dioxide and starch value have specification entries, while the public lot results are redacted. A current comparison needs an unredacted certificate tied to representative sampling, laboratory and method, plus exact native or modified form, maize type, process, food, feed or technical grade, package and quantity, origin, currency, Incoterm, destination, delivery window, freight and information vintage. Atlas withholds a physical estimate when permitted current observations or usage rights are missing.

Questions procurement teams ask

Are corn starch, cornmeal and corn flour the same product?

No. Corn starch is the separated starch fraction. Meal and flour retain different grain components and have different composition, particle-size, processing and end-use specifications.

Are native and modified corn starch interchangeable?

No. Pregelatinization, physical or enzymatic treatment, chemical modification and high-amylose genetics can change functionality, declarations, residual controls and value. Each observation stays attached to its exact form and process.

Do the numbers on the FDA-hosted certificate prove the lot passed?

No. The public attachment shows the supplier's specification values but redacts the analysis results. Atlas treats those numbers as a dated product-specification example, not an FDA standard or a verified lot certificate.

Which fields make corn-starch offers comparable?

Maize source and variety, native, pregelatinized, high-amylose or modified status, treatment process, intended use, amylose basis, moisture, starch value or purity, protein, fat, ash, pH, sulfur dioxide, particle size, microbiological, mycotoxin, metal and allergen evidence, package and lot, quantity, origin, currency, Incoterm, destination, delivery window and evidence date.
