Vitamin Analysis
Fat- and water-soluble vitamin quantification by HPLC and LC-MS/MS for foods, premixes and fortified products.
About Vitamin Analysis
Vitamin claims on a label are only as good as the assay behind them, and vitamins are notoriously unstable through processing and storage. CVR Labs quantifies fat-soluble vitamins (A, D, E, K) and water-soluble vitamins (C and the B-complex) in foods, premixes, fortified rice kernels, dairy, beverages and supplements using HPLC and LC-MS/MS calibrated against certified reference standards.
We support both label verification — confirming the declared level is actually present — and stability studies that track vitamin loss across shelf life so overages can be set correctly. For fortification programmes (FRK, fortified atta, edible oil with A and D), accredited vitamin assay is the evidence that the public-health add-on is genuinely delivered.

What we analyse under Vitamin Analysis
The parameter groups below are drawn from this service's own accredited scope; the full searchable list follows.
Vitamins degrade — claims drift
Vitamin C, A and folic acid decay through processing and storage; only assay at release and over shelf life proves the claim still holds.
Overages must be set on data
Manufacturers add a vitamin overage to survive shelf life — accredited stability data sets that overage correctly instead of by guesswork.
Fortification needs proof of delivery
FRK, fortified oil and atta must deliver the mandated vitamin level; assay is the evidence the programme requires.

How Vitamin Analysis is tested
Reference methods applied
Where more than one standard applies, the appropriate method is selected for each sample and regulatory requirement. The B-complex, fat-soluble vitamins (A, D, E, K) and vitamin C are quantified by validated in-house CVR LC-MS/MS SOPs against certified reference standards; the qualitative Carr-Price screen for vitamin A in oils follows the FSSAI Manual of Methods — all within the accredited scope.
