Vitamins

Vitamins are essential nutritional components that humans and animals must ingest with their food, and which with the exception of vitamin D are not produced by the body itself. They fulfil the widest range of metabolic processes, and are required for growth, cell renewal and many other processes. A balanced diet is usually enough to meet daily vitamin requirements. However, many foods are fortified with vitamins, and this is subject to compulsory declaration.

The Institut Kirchhoff Berlin GmbH is your partner for questions relating to the chemical and biochemical analysis of endogenous as well as supplementary vitamins. Furthermore, we also offer legal assessments of your products’ marketability and correct nutritional labelling. Our range of services therefore spans the analysis of all water-soluble and fat-soluble foodstuffs and feeds, from raw commodities right up to the finished product.

The use and optimisation of standardised inspection procedures (eg DIN EN, SLMB), as well as the development and validation of new, more effective methods enables us to analyse more than 20,000 sample parameters a year. Thanks to regular participation (on average 6x a year) in various proficiency inspection systems (DGF, DRRR, FAPAS, LVU) our performance and continuous quality is guaranteed by independent inspections. We are also an active member in the section 64 LFGB ‘Vitamins’ working group and in the DIN ‘Vitamins and carotinoids’ working group.

For more information on this topic, our regularly trained staff would be pleased to assist.
