As proteínas são bastante utilizadas na indústria alimentícia para o melhoramento da textura dos produtos e são de extrema importância para a nutrição humana. Esse estudo avaliou o conteúdo de proteína total de três derivados lácteos diferentes: bebida láctea, requeijão cremoso e cream cheese, de três marcas comerciais distintas, e comparou com a rotulagem nutricional dos produtos. Todas as marcas diferiram entre si estatisticamente, com nível de significância de 95% pelo teste de Tukey. Apenas uma amostra de bebida láctea diferenciou significativamente das demais (p<0,05), enquanto que para o requeijão cremoso, as três marcas diferiram do valor descrito no rótulo e no cream cheese houve diferença nas marcas C1 e C3 (p > 0,05). Somente a marca C3 do cream cheese ficou fora dos padrões de rotulagem, as demais marcas apresentaram diferença significativa, porém estavam em conformidade com legislação brasileira vigente. Como o cream cheese não possui uma legislação brasileira específica para o conteúdo de proteína, os valores são bastante variáveis. Entretanto, em relação à rotulagem nutricional, a ANVISA preconiza que o valor real não deve exceder a 20% do valor informado. Sendo assim, é importante a fiscalização dos produtos lácteos no tocante à informação nutricional para que o consumidor seja devidamente orientado. Palavras-chave: Bebida Láctea.

This study evaluated the total protein content of three different dairy products: dairy drink, cream cheese and cream cheese, from three different brands, and compared it with the nutritional labeling of the products. All the marks differed statistically, with a level of significance of 95% by the Tukey test. Only one sample of milk beverage differed significantly from the others (p <0.05), whereas for cream cheese, the three brands differed from the value described on the label and cream cheese showed differences in the marks C1 and C3 (p> 0, 05). Only the C3 brand of cream cheese was outside the labeling standards, the other brands presented significant difference, but were in compliance with current Brazilian legislation. As cream cheese does not have specific Brazilian legislation for protein content, the values are quite variable. However, in relation to nutritional labeling, ANVISA recommends that the actual value should not exceed 20% of the reported value. Therefore, it is important to monitor dairy products with regard to nutritional information for the consumer to be properly oriented. Keywords: Milk Beverage. Nutrition Facts. Cream Cheese.
