Before you source Glycine, understand what it does in Food & Feed Raw Materials

Glycine (CAS 56-40-6) looks like an ordinary Food & Feed Raw Materials raw material, yet its behaviour swings a lot across process windows. Across a batch of real selection cases we kept seeing the same few failure points — this page lays them out.

Starting with the mechanism

Most people's first guess is off — here's why:

In Food & Feed Raw Materials, the first split for Glycine (CAS 56-40-6) 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:

• Magnesium Carbonate (CAS 546-93-0)：a comparable grade often evaluated alongside。
• disodium malate (CAS 676-46-0)：a comparable grade often evaluated alongside。
• Gluconic acid, sodium salt (CAS 527-07-1)：a comparable grade often evaluated alongside。
• N-gamma-ethyl-L-glutamine (CAS 3081-61-6)：a comparable grade often evaluated alongside。
• Sodium succinate (CAS 150-90-3)：a comparable grade often evaluated alongside。
• L-Glutamic acid (CAS 56-86-0)：a comparable grade often evaluated alongside。
• Glucose oxidase (CAS 492-61-5)：a comparable grade often evaluated alongside。
• CALCIUM5'-RIBONUCLEOTIDES：a comparable grade often evaluated alongside。

Key selection dimensions

The single most important one: 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 Glycine, CAS 56-40-6, formula C2H5NO2, MW 75.03 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.

Mistakes people make

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.

The ones you'll likely ask

Where is Glycine 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 Glycine?

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.
