Abstract

It was found that the milking of cows with robotics has a greater influence on formation of free fatty acids (FFA) in milk than automatic milking "Carousel." Among all researched FFA, the largest concentrations in milk were palmitic, oleic and stearic fatty acids. Pseudomonas spp in milk during refrigerated storage secrete lipase, promoting the FFA formation. Adding a solution of H2O2 to raw milk stops the formation of bacterial lipases.
