Description

technical field [0001] The invention belongs to the technical field of food detection, and relates to a detection device and method for the total number of bacteria on the surface of cooled mutton, in particular to a detection device and method for the total number of bacteria on the surface of cooled mutton based on hyperspectral and extreme learning machines. Background technique [0002] Mutton has low fat content and high protein content. Compared with pork, chicken and other meats, the various mineral elements contained in it, such as calcium, phosphorus, iron and other minerals, are significantly increased, and it is an ideal source of green animal protein. With the gradual improvement of people's living standards, people pay more and more attention to issues such as health and safety, and the demand for chilled meat is increasing, which represents the mainstream direction of future meat products. However, contamination during slaughter and transportation of mutton ine...
