Vitamins, in the correct amounts, are vital for human health. Each vitamin has a different function in the human body. Manufacturers need to be confident in the vitamin declaration they make on their products to meet legislation and for consumer confidence. The analysis of different vitamins in foods requires different methods for an accurate determination.
Participants will be asked to report vitamin A as retinol (the sum of cis and trans isomers), vitamin D3 as cholecalciferol (molecular weight 384.64), vitamin C as the sum of L(+)ascorbic acid and dehydro L(+)ascorbic acid, vitamin E as the sum of D-alpha-tocopherol and L-alpha-tocopherol.
Infant formula usually is responsible for a large amount of the nutritional requirements needed by infants within this crucial development phase of their lives. The ability to assess the vitamin intake claimed within infant food is therefore extremely important.
This requires your effective testing ability to be safeguarded across a range of vitamins and other nutrients. To achieve this proficiency testing activities from Fapas should be utilised as part of a wider quality assurance programme, from which to highlight areas of improvement and promote high quality, accurate testing.
Fapas reference materials provide effective tools to build and provide ongoing detail to quality improvement efforts. By building on the snapshot of proficiency testing activities, a long term picture of your laboratory's testing ability can be provided, to impress both accreditors and potential customers of your testing credibility.
Reference materials can be used to both standardise your testing arrangement through instrument calibration and staff training activities. Reference materials are also a valuable asset for method verification due to the known uncertainty present within the material and accompanying data sheet.
