"Milk is a unique animal product secreted by mammary gland during the lactation with high content of natural occurring biological active substances that exert various important roles in metabolism. The feeding strategy and food production are changed with time. Milk is very good source of riboflavin but only low source of folates but the worldwide strategy for attaining safe levels of folates in overall nutritional status is intake from natural food sources. The objective of this study was to determine the hydrophilic vitamin riboflavin and for folates ? 5-methyl-tetrahydrofolate and tetrahydrofolate, which occurs in milk, apply the analytical separation method HPLC with fluorescence detection. Sample extraction for folates is based on enzymatic hydrolysis after heat extraction from proteins and main step for riboflavin is acidic hydrolysis. The actual average content of riboflavin in raw cow's milk samples obtained from different dairy farms in the Czech Republic from May to December 2012 is 0,99 mg.l-1 for riboflavin. Data was obtained by HPLC method with FLD detection."@en . . . . . "Zborn\u00EDk predn\u00E1\u0161ok a posterov Hygiena Alimentorum XXXIV." . . . . "Milk as a source of certain B-group vitamins"@en .
