摘要
On the basis of variation ranges of fatty acids (83 milk fats) and triglycerides (763 milk fats) the limits of detection of foreign fats (13 different types) in milk fat are determined. In this respect, on the basis of certain ratios of triglycerides only for soybean oil, sunflower oil, and olive oil and also of ratios of fatty acids only for soybean oil, sunflower oil, coconut oil and palm kernel oil low limits of detection of < 5% were established. On the other hand triglyceride formulae with up to 8 individual triglycerides permit a sensitive qualitative (2-5%) and quantitative detection of all vegetable and also animal non-milk fats in milk fat, even with special feeding conditions of the cows (e.g. fats, Ca-soaps).
