Scope: What is ISO 17678- Determination of milk fat purity in milk and milk products about? ISO 17678 discusses milk and milk products. ISO 17678 is an international standard on the determination of milk fat purity in milk and milk products to classify the milk for the preparation of derivatives. ISO 17678 specifies a reference method for the determination of milk fat purity using gas chromatographic analysis of triglycerides. The method specified by ISO 17678 applies to bulk milk, or products made thereof, irrespective of the variation in common feeding practices, breed, or lactation conditions. In particular, the method applies to fat extracted from milk products purporting to contain pure milk fat with unchanged composition, such as butter, cream, milk, and milk powder. Note 1: Because a false-positive result can occur, the method specified under ISO 17678 does not apply to milk fat related to these circumstances: Obtained from bovine milk other than cow’s milk Obtained from single cows Obtained from cows whose diet contained a particularly high proportion of vegetable oils such as rapeseed, cotton, palm oil, etc Obtained from cows suffering from serious underfeeding (strong energy deficit)
