Description

technical field [0001] The invention relates to the technical field of meat quality detection, in particular to a spliced ​​mutton detection device and a detection method that can accurately and quickly detect spliced ​​mutton. Background technique [0002] Mutton has the characteristics of rich nutrition and good taste, and is deeply loved by consumers. However, due to its high production cost, especially high-grade mutton pieces, the price is high. The spliced ​​mutton is spliced ​​from pieces of mutton of different sizes, which not only tastes bad, but also causes contamination between mutton pieces from different sources, causing food safety problems. [0003] At present, the spectral excitation light source is usually used at home and abroad to irradiate the sample under test (that is, a normally-on halogen lamp or LED lamp is used to illuminate the sample), and the diffuse reflection light or the transmitted light passing through the sample is collected after the inci...
