Selecting Citric acid: role, specs and pitfalls in Food & Feed Raw Materials
Putting Citric acid (CAS 77-92-9) into Food & Feed Raw Materials brings up a phrase you'll hear more than you'd expect: can this batch run on our line? To answer that honestly, you can't lean on the labelled figure alone. This page lists the checks that actually matter.
Let's get the mechanism first
Before jumping to conclusions —In Food & Feed Raw Materials, the first split for Citric acid (CAS 77-92-9) 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:
- Calcium Hydroxide (CAS 1305-62-0)：a comparable grade often evaluated alongside。
- Calcium perphosphate,ammonified,granular (CAS 7757-93-9)：a comparable grade often evaluated alongside。
- tripotassium citrate anhydrous (CAS 7778-49-6)：a comparable grade often evaluated alongside。
- Potassium carbonate (CAS 584-08-7)：a comparable grade often evaluated alongside。
- dl-lactic acid sodium salt (CAS 72-17-3)：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。
- Sodium dihydrogen citrate Anhydrous (CAS 18996-35-5)：a comparable grade often evaluated alongside。

Purity and packaging follow the batch COA and order confirmation.
Checks worth running before you order
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.
What newcomers overlook
- 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 Citric 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 Citric 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 Citric acid?
For Citric acid, the molecular formula is C6H8O7 and molecular weight about 192.03 g/mol (CAS 77-92-9). These are published physical properties; exact purity, specification and packaging follow the batch COA and order confirmation.
