Core Viewpoint - The newly revised standard for identifying reconstituted milk in pasteurized and UHT sterilized milk will be implemented on April 1, 2016, providing a scientific basis for regulating the illegal addition of reconstituted milk in China [1][2] Group 1: Standard Revision - The standard was revised by the Beijing Institute of Animal Husbandry and Veterinary Medicine of the Chinese Academy of Agricultural Sciences and the Dairy and Dairy Products Quality Supervision and Inspection Testing Center (Beijing) [2] - The revision includes the addition of a method for determining furfural using ultra-high performance liquid chromatography and modifications to the existing method for measuring lactulose, effectively shortening detection time and improving efficiency [2] Group 2: Identification Method - The standard selects two markers, furfural and lactulose, which are by-products formed during the thermal processing of milk, with very low levels in fresh milk [1] - A model is established to determine whether reconstituted milk has been added to pasteurized and UHT sterilized milk by measuring the content of furfural and lactulose in fresh milk, pasteurized milk, UHT milk, and milk powder, along with their ratios [1]
