Abstract

The invention discloses a pseudosciaena crocea freshness detection device and a detection method. The detection device comprises a laser array, a spectrometer, a light intensity adjustment instrument, a light emission head used for emitting incident light to a sample, a bracket and a light receiving instrument. The bracket comprises a bottom plate, a sample support plate over the bottom plate, a light-transmitting plate disposed on the sample support plate and an L-shaped fixation arm disposed on the edge of the bottom plate. The L-shaped fixation arm includes a horizontal plate positioned above the sample support plate and a vertical bar that passes through the sample support plate and is fixedly connected to the sample support plate. A horizontal plate's part over the light-transmitting plate is provided with a vertical extension arm extending toward the light-transmitting plate. The device and the method provided by the invention have the characteristics of fast detection speed, more detection points, and higher data detection reliability and precision.

Description

technical field [0001] The invention relates to the technical field of meat quality detection, in particular to a large yellow croaker freshness detection device and detection method that can accurately and quickly detect whether the large yellow croaker is spoiled. Background technique [0002] Large yellow croaker belongs to the Sciaenidae family (Sciaenidae), also known as yellow croaker and stone head fish. Large yellow croaker is a dry-swimming fish clustered in warm-temperate coastal waters, and its main activity area is south of the central part of the South China Sea. Because it contains a large amount of selenium, it can better scavenge free radicals and beautify the skin. In addition, large yellow croaker is very rich in protein, and its meat is relatively delicate, which can be used as one of the ideal animal protein sources for human beings. Large yellow croaker is known as my country's four major economic fishes, especially in the development of marine fisheri...
