ABSTRACT
The aim of this research was to evaluate the levels of enrichment of vitamins B1, B2, B6, B3 and B12 in vanilla, strawberry and chocolate flavored milk. The chromatographic separation was performed in a C18 column with gradient elution and UV detector at 254, 278 and 358 nm. The B12 levels were the most near of the values declared in the package of the analysis products, while the vitamin B2 levels were found between 20-150% more than the package value. In general, the levels of vitamins determined in the samples were higher than the declared values on the labels and did not be in accordance with the legislation to enriched foods.
