Detection system and method for total number of bacteria in livestock meat

Abstract

The invention discloses a detection system for the total number of bacteria in livestock meat. The detection system comprises a light source apparatus emitting a spot light source to irradiate a livestock meat sample, a hyperspectral imaging apparatus used for acquiring spectral information of the livestock meat sample, an electric adjusting apparatus used for adjusting the position of the livestock meat sample and the position of the hyperspectral imaging apparatus, a controller apparatus used for controlling the motion of a motor of the electric adjusting apparatus, a sensor apparatus used for determining the position of the livestock meat sample and the position of the hyperspectral imaging apparatus and outputting position signals, a computer processor used for receiving the position signals, outputting processed position signals to the controller apparatus, analyzing hyperspectral information of the livestock meat sample and outputting analysis results and a dark box used for placement of the hyperspectral imaging apparatus. According to the invention, automatic real-time detection and real-time outputting of detection results are realized, experiment efficiency and accuracy are improved, obtained results are more reliable, and an operation method of the detection system is simple.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of food, in particular to a non-destructive rapid real-time automatic detection device system and method for the total number of bacteria in fresh meat based on hyperspectral imaging. Background technique [0002] China is a big pork production and consumption country, and the hygienic condition and quality safety of pork has always been the focus of attention. Fresh pork is usually slaughtered in the early morning and marketed in the early morning without any cooling treatment. Although the hygienic inspection has passed after slaughtering and processing, in the process from processing to retailing, the meat will inevitably be polluted by air, insects, transport vehicles and packaging, etc., and the temperature of the meat in these processes is high, and bacteria are prone to contamination. A large number of proliferation, can not guarantee the safety of meat consumption. [0...

AI Technical Summary

Problems solved by technology

At present, the methods for detecting the total number of bacteria in pork include plate colony counting method (national standard method), electrical impedance detection method, polymerase chain reaction (PCR) method, micro-colony counting, etc. Although these methods are effective, they take a long time for sampling preparation and detection , low efficiency, cumbersome operation, lagging test results, destructive to the sample, and difficult to automate, not suitable for real-time detection, can not fully meet the needs of domestic consumption and export trade
