Milk, by nature, is a nutrient-rich food containing proteins, carbohydrates, fats, vitamins and minerals. Therefore, it is called milk quality, the one whose chemical composition, microbiological, organoleptic quality parameters meet internationally required and must be free of antibiotics, disinfectants and contaminants and be from herds with health monitored. Its quality is one of the most discussed topics currently in the national stage of milk production, even though it is known that in general, the milk produced here has high counts of microorganisms, characterizing it with deficiencies in hygiene of its production. Among the several tests performed to evaluate the quality of milk produced, one of the most used is the alcohol test, conducted on the property before loading the milk. Positive results can be detected when there is acidification of milk due to the presence of bacterial cultures, and more recently has been described in several studies to casein instability unrelated to acidity known by the acronym LINA. These results lead to confusion, because milk is wrongly interpreted as an acid, without penalizing the producer that can identify what happens in the herd. This work aims to detect in a time of year it occurs and to evaluate possible causes of this instability, analyzing aspects hygienic, nutritional and management of livestock in the region.
