Fermented milk beverage is a product containing milk, whey and/or other ingredients, fermented by specific microorganisms and/or added with fermented milks. Fat determination in this product is important to quality control and inspection. The Gerber method is used worldwide as a simple and rapid method for fat content analysis in raw and processed milks. In Brazil, Roese-Gottlieb is the official method for analysis of fat content in milk beverages. However, the use of Gerber method for fat content determination in fermented milk beverages is widespread throughout the industry in the country. Several authors have tested the use of Gerber method for some dairy products, but there is no report on this evaluation for fermented milk beverages. In this context, the objectives of this work were to determine the fat content of fermented milk beverages by the Gerber method and evaluate the performance of this test, using Roese-Gottlieb as a reference method. Thirty samples of fermented milk beverages were analyzed by both methods. The fat contents ranged from 1.25 to 2.40% by the Gerber method and from 1.24 to 2.50% by the Roese-Gottlieb method. There was no difference (p > 0.05) between the methods. The Gerber method can be used to determine the fat content of fermented milk beverages, without prejudice to the results obtained.(AU)
