| Abstract: | Milk is rich in various nutrients, including functional proteins, which have many benefits for human health. However, milk must undergo heat treatment before being marketed. The stronger the heat treatment of milk, the greater the loss of functional proteins. Lactulose is one of the important heat sensitive indicators in milk, which can indicate the heat treatment intensity of milk. The Animal Husbandry Department of the Ministry of Agriculture proposed to conduct lactulose detection on pasteurized milk. However, the current method cannot quickly meet business needs due to complex operation, long detection time, and the need to convert enzyme activity. Therefore, a lactulose rapid detection kit is used to improve detection efficiency and shorten detection time while ensuring the accuracy of detection results. This article provides a detailed introduction to the detection method of lactulose test kit (Fushen) from the aspects of laboratory material preparation, key steps and precautions in detection operation, and comparative data analysis. It is concluded that the test kit method is superior to traditional detection methods in terms of accuracy, detection time, ease of operation, and detection cost. |
