Abstract

The production of quality milk is an important factor for consolidating the production chain and, consequently, guaranteeing food safety for consumers and better industrial performance. Thus, the objective was to evaluate the composition and microbiological quality of milk from the microregion of Itapetinga, State of Bahia, Brazil, in the period between September and October 2017. 86 samples of raw milk were obtained from crossbred giralando cows from producers, the samples were forwarded to the Center for Milk Studies at UESB. To evaluate the composition, the samples were analyzed in DairySpec FT equipment and the levels of fat, true protein, lactose, total solids and cryoscopic index were obtained. For CBT and CCS analysis, the BactoCount IBC equipment was used. The data obtained were organized and evaluated using descriptive statistics. The fat, protein, lactose, and total solids contents showed averages that comply with the legislation, only for the cryoscopic index, the average does not meet the range defined by the current legislation of the year 2018, which remains the same for the year 2023, being higher than the established minimum value. Evaluating each individual producer, it was observed that 4 producers do not comply with the legislation for fat, 22 for protein and 6 for total solids, and only 1 for cryoscopic index. Evaluating the values of 67% and 60% of the producers do not meet the standards defined by the current legislation for CBT and CCS, respectively. The average results for composition showed satisfactory values within the standards established by Brazilian legislation. The microbiological conditions of the analyzed raw milk are unsatisfactory, where most of the producers presented indexes far above the established by the current legislation.
