This standard BS EN 12823-1:2014 Foodstuffs. Determination of vitamin A by high performance liquid chromatography is classified in these ICS categories:
- 67.050 General methods of tests and analysis for food products
This European Standard specifies a method for the determination of vitamin A in foodstuffs by high performance liquid chromatography (HPLC). This method has been validated in an interlaboratory study with samples of margarine and milk powder with all-E-retinol levels ranging from 653 µg/100 g to 729 µg/100 g and with 13-Z-retinol levels ranging from 30 µg/100 g to 39 µg/100 g. The determination of vitamin A content is carried out by the measurement of all-E-retinol, 13-Z-retinol and β-carotene. This part covers the measurement of all-E-retinol and 13-Z-retinol.
The extract obtained after saponification in this method can be used for the determination of β-carotene, as described in EN 12823-2:2000, Foodstuffs - Determination of vitamin A by high performance liquid chromatography - Part 2: Measurements of β-carotene. In this case, the saponification temperature should preferably not exceed 80 °C in order to prevent isomerisation and oxidation of β-carotene.
