The research compared fresh cow’s milk from various farms on a number of indicators, including fatty acid and triglyceride composition. The resulting minimal and maximal values for each fatty acid made it possible to reveal the effect of various factors on the fatty acid composition. The triglyceride test demonstrated the dominant triglycerides and their mass fraction typical of cow’s milk fat. Some samples had an altered triglyceride composition with bovine fat mixed with milk fat. The main triglyceride groups were classified as C50, C52 and C54, which are characteristic of cow’s milk fat: they proved dominant when the fat phase samples were analyzed for bovine fat. The method proved effective in cow’s milk fat phase triglyceride tests.
