Food Additives, Preservatives & Colours Testing
Synthetic colours, preservatives, sweeteners and antioxidants quantified against FSSAI permitted limits.
About Food Additives, Preservatives & Colours
Food additives are legal only within defined limits and only in permitted categories, and misuse — a non-permitted colour, an over-dosed preservative — is one of the most common FSSAI surveillance failures. CVR Labs quantifies synthetic colours (tartrazine, sunset yellow, carmoisine, ponceau 4R, brilliant blue), preservatives (benzoate, sorbate, sulphite, nitrite), artificial sweeteners and antioxidants across beverages, confectionery, bakery, sauces and processed foods.
We confirm whether a colour or preservative is permitted in your product category and whether its level sits within the FSSAI maximum, by HPLC and LC-MS/MS. For manufacturers this verifies recipe compliance before launch; for importers and surveillance it exposes non-permitted or excess additives that trigger recall.

What we analyse under Food Additives, Preservatives & Colours
The parameter groups below are drawn from this service's own accredited scope; the full searchable list follows.
Non-permitted colours are a top failure
A synthetic colour legal in one food is banned in another; using it in the wrong category is a frequent and avoidable FSSAI violation.
Preservatives have category limits
Benzoate, sorbate and sulphite are capped by product type; over-dosing to extend shelf life breaches the standard.
Sweeteners must be declared and limited
Saccharin, aspartame and acesulfame-K are permitted only within limits and with mandatory declaration.
