Using Lactic acid in Food & Feed Raw Materials: a few gates to clear first

Lactic acid (CAS 50-21-5) isn't a “buy and it works” material. In Food & Feed Raw Materials, its compatibility with the rest of the system and the dosing rhythm usually matter more than the nominal assay.

What it actually does here

Bottom line first, then the why:

In Food & Feed Raw Materials, the first split for Lactic acid (CAS 50-21-5) is 'industrial grade' vs 'food / feed grade' — they are not interchangeable. Food and feed grades carry stricter statutory limits on heavy metals, arsenic, microbes and residues, usually backed by corresponding licences and test reports. Regulatory grade and traceability come before the assay figure. Comparable grades:

• lactic acid fatty acid glycerides：a comparable grade often evaluated alongside。
• Lactic acid esters of mono- and diglycerides：a comparable grade often evaluated alongside。
• LACTIC ACID POWDER (CAS 10326-41-7)：a comparable grade often evaluated alongside。
• Lactic Casein：a comparable grade often evaluated alongside。
• Lactic acid, lithium salt (CAS 867-55-0)：a comparable grade often evaluated alongside。
• Lacticacidisoamylester: 98% (CAS 19329-89-6)：a comparable grade often evaluated alongside。
• Lactic acid, 2-acetamido-, methyl ester (8CI)：a comparable grade often evaluated alongside。
• LACTIC ACID ZINC SALT (CAS 16039-53-5)：a comparable grade often evaluated alongside。

How to get the choice right

Most practically, the top item is: Confirm the required grade (food / feed / industrial) — never substitute industrial for food or feed use.

Request and verify test reports for heavy metals, arsenic, microbes and residual solvents against the applicable standard or customer spec.

Mind moisture-proof, contamination-free packaging and transport to avoid drift on arrival.

Retain samples of critical lots and keep incoming-inspection records for traceability and retest.

Its typical specs: name Lactic acid, CAS 50-21-5, formula C3H6O3, MW 90.08 g/mol, standard purity per batch COA, packaging confirmed per order, storage keep sealed in a cool, dry place. Final values follow the batch COA and order confirmation.

A few common pitfalls

Using industrial grade in place of food / feed grade: statutory limits differ and mixing them triggers compliance and safety risk.

Watching assay but ignoring traceability: without the correct grade's test report, even high purity cannot enter the food / feed chain.

Loose storage and transport: moisture or cross-contamination can make a compliant lot fail on arrival.

Things we get asked a lot

Where is Lactic acid used in Food & Feed Raw Materials?

As a common raw material it serves nutritional fortification, stabilisation or process aid; the exact use depends on the finished product and regulatory grade.

Which grade and documents should I confirm when sourcing Lactic acid?

State food / feed grade requirements and verify safety indicators (heavy metals, microbes) test reports against the applicable standard or customer spec.

Can industrial grade be used as food / feed grade?

No. Products here are supplied for industrial and research use; food or feed use requires the correct grade with full compliance documentation.

What is the molecular formula and weight of Lactic acid?

For Lactic acid, the molecular formula is C3H6O3 and molecular weight about 90.08 g/mol (CAS 50-21-5). These are published physical properties; exact purity, specification and packaging follow the batch COA and order confirmation.
