Abstract

Concentração de retinol em bebidas lácteas achocolatadas enriquecidas em comparação às quantidades declaradas no rótulo Retinol concentration in milk chocolate beverages compared to the amounts declared on the labelMilk chocolate beverage is a dairy product widely consumed and can be enriched with essential nutrients to enhance its nutritional value and prevent or correct specific deficiencies in the population, especially in children. One of these nutrients is vitamin A, whose deficiency is considered a public health problem. This study aimed to quantify the retinol present in fortified achocolatadas Ultra High Temperature -UHT milk chocolate beverage and check its compatibility with the values specified on the label. For this purpose, were randomly selected three brands of these products (A, B and C), analyzed by High Performance Liquid Chromatography (HPLC). The concentration of retinol is given in μg/dL and values expressed as mean and standard deviation. The results show that brands A and C had retinol concentration consistent with that described on the label (70.5 ±6.8 μg/dL and 73.5 ±8.2 μg/dL). However, the brand B had a very low concentration (9.0 ±3.2 μg/dL), in conflict with the declared (75.0 μg/dL). This situation
