The invention relates to a beef freshness detection system and method to solve the problems of subjective and inaccurate detection of beef freshness and complex detection process of detection equipment in the prior art. The system comprises a seat body, the seat body is provided with a bracket, and an irradiation light source is arranged above the bracket. The irradiation light source is rotatably connected to an adjustment mechanism for adjusting the position of the irradiation light source, and the adjustment mechanism is installed on the seat body. A receiving mechanism is disposed below the bracket, and a control unit is disposed in the seat body and is in connection with the irradiation light source, the adjustment mechanism and the receiving mechanism. By analyzing sample reflection or transmission spectrum data, the beef freshness can be judged. By adopting the spectrum detection mode, nondestructive detection can be carried out on samples. The device structure is simple, the operation is fast and simple, and the detection data are accurate.
Description
technical field [0001] The invention relates to the field of food detection, in particular to a beef freshness detection system with simple structure, quick and easy operation and accurate detection, and a detection method of the system. Background technique [0002] Meat consumption has always been an important part of food consumption, and beef is a favorite food for consumers. In recent years, people's concept of life has changed, health awareness has been continuously enhanced, and the requirements for the quality and hygiene conditions of meat food have become more and more stringent. The safety of meat food is related to the life safety of ordinary people and social stability. become more and more important in daily life. At present, the detection techniques for beef freshness include sensory detection, physical and chemical detection, etc. Sensory testing is often affected by reviewers’ experience, psychology, and physical factors. Different reviewers may have diffi...
