Vitamins in Focus: Why Composition Analysis is a Fundamental Standard, Not a Luxury

You cannot see vitamins with the naked eye, or taste or smell them. Yet it is precisely these microscopic compounds that determine whether your product will be beneficial to people and whether it will bring profit to a farm.
For a food or feed manufacturer, vitamin composition analysis is not merely a box to tick on a report. It is a matter of reputation, safety and economic efficiency. Today we shall explore why this analysis is critically important and exactly how chemists "extract" vitamins from complex mixtures.

Why is vitamin analysis the number-one issue for a manufacturer?

1. Food products: consumer trust and the law
Today's shopper reads the label carefully. If you claim that your juice is "enriched with vitamin C", or that your cereal contains "a daily dose of B vitamins", you must be able to prove it.
Label compliance: A discrepancy between the declared and the actual composition is a direct route to fines and reputational damage.
Shelf life: Vitamins are exceptionally fragile molecules. They break down under the influence of light, oxygen and temperature. Analysis makes it possible to determine how many vitamins will remain in the product at the end of its shelf life.
2. Animal feeds: the mathematics of profit
In animal husbandry, vitamins are catalysts for growth.
Hypovitaminosis = losses: A shortage of vitamin A in feed leads to problems with the reproductive system, while a deficiency of vitamin D leads to weak bones and a decline in the quality of eggs or milk.
Formulation optimisation: Premixes are expensive. Laboratory control helps you avoid "overfeeding" animals with costly additives, while also preventing critical deficiencies.

How does it work? A simplified look at complex chemistry

To a non-chemist, a laboratory may seem a magical place, but vitamin analysis is a clearly defined technological process. We can divide it into three main stages.
Stage 1: "Releasing" the vitamin (sample preparation)
This is the most difficult stage. In products, vitamins are "hidden" inside proteins, fats and carbohydrates.
Chemists use special solvents, enzymes or acids to break down the structure of the product and bring the vitamins into solution.
The challenge: Vitamin C dissolves readily in water, whereas vitamins A and E dissolve only in fats. Each group therefore requires its own approach.
Stage 2: Removing the "noise"
Imagine you need to find one particular person in a stadium full of people. A product sample is just such a "crowd" of sugar, pigment and mineral molecules. Using special columns (extraction), chemists cut away everything unnecessary, leaving only the target group of vitamins.
Stage 3: Measurement (HPLC — the gold standard)
The most accurate method of vitamin analysis today is HPLC (High-Performance Liquid Chromatography).
How it works: The purified solution is passed under high pressure through a fine column packed with a special sorbent. Each vitamin passes through this column at a different rate.
At the output, a detector records "peaks". The time at which a peak appears tells us which vitamin it is, and the height of the peak tells us how much of it is present.

Which vitamins are analysed most often?

Laboratories usually divide their analyses into two groups:
Fat-soluble (A, D, E, K): important for immunity, vision and metabolism. They accumulate in the body, so an excess is just as dangerous as a deficiency.
Water-soluble (the B group, C): these are energy and metabolism. They are excreted quickly, so their constant presence in the diet (of humans or animals) is essential.

Summary: When should you turn to a laboratory?

If you:
● are developing a new formulation for a product or feed,● want to verify the reliability of a raw material supplier,● are preparing documents for export (where quality requirements are far stricter),● wish to optimise your spending on vitamin additives.
Vitamin analysis is an investment in the stability of your business. Knowing the exact composition gives you the confidence that your product truly performs as you promise your customer.
