For chemicals for the food industry, food-grade means the substance is made to a recognised food specification, in a plant with food safety controls, and comes with paperwork that proves it. A technical grade product with a food-grade label is not acceptable, even when it looks pure.
The grade categories are explained in technical, industrial, food and pharma grade chemicals. This article focuses on the documents you should demand from India.
What specification applies?
Food ingredients and additives are normally bought against a named specification, such as a pharmacopoeia-style food chemicals compendium or the specifications in the food additive law of the destination market. In the EU, additives have E-numbers and purity criteria set in legislation; the United States and other markets use their own lists.
Ask your supplier to state which specification the product meets, and to give the test results on a certificate of analysis for each lot. Limits for lead, arsenic and other heavy metals, and microbiological counts where relevant, are usually part of the specification.
What does the plant need to show?
A general quality certificate is not the same thing. See what certifications a chemical manufacturer should have for the difference, and check that the scope on the certificate covers your product.
- A food safety management certificate recognised in your market, for example one of the schemes benchmarked by the Global Food Safety Initiative, covering this product and site.
- A hazard analysis (HACCP) for the product, including controls against cross-contamination from non-food lines.
- Dedicated or validated cleaning of equipment, and separation from technical-grade production.
- Food-grade packaging, such as new liners, clean drums and sealed bags, with traceable batch codes.
- Allergen, GMO and origin statements where the buyer or market requires them.
Which chemicals commonly cross over?
Common examples are acids such as citric and phosphoric acid, phosphates, bicarbonates, preservatives and acidity regulators, plus colours. Food colours are regulated separately and often need approval on a permitted list; see food-grade colours from Gujarat.
Whatever the item, the same chemical name can be sold as technical and food grade by one plant. The difference is in the specification, the line and the records.
Who carries the legal risk?
As importer or brand owner, you are usually responsible for placing compliant food ingredients on your market. That includes being sure the additive is permitted for your use and within limits. Confirm with your food safety adviser or the competent authority, and use the supplier's documents as evidence, not as a substitute.
Plan an audit of the plant and a pre-shipment test, because a food-grade claim without checks carries serious risk.
Keep the supplier's certificates, specifications and audit reports in one file for each product, with dates. If an authority or customer asks how you know an ingredient is fit for food, that file is your answer. Renew it whenever the supplier changes site, process or packaging, and when a certificate expires. Also agree that the supplier will tell you in advance of any such change, because it can alter the food safety status of the product.
