Food-borne pathogenic bacterium detection system and method based on high spectrum

Abstract

The invention discloses a food-borne pathogenic bacterium detection system based on a high spectrum. The food-borne pathogenic bacterium detection system comprises a surface detection line, a sorting line, a qualified product conveying belt and a point detection line, which are connected with a control system respectively. The invention further discloses a detection method of the food-borne pathogenic bacterium detection system based on the high spectrum. The surface detection line based on a near-infrared high-spectrum system is used for rapidly positioning food-borne pathogenic bacteria; the sorting line is used for conveying pork polluted by the food-borne pathogenic bacteria to the point detection line; Raman chemical imaging is used for realizing species identification of the food-borne pathogenic bacteria. According to the food-borne pathogenic bacterium detection system disclosed by the invention, the problems that the resolution ratio of detecting a microorganism cell structure by the near-infrared high-spectrum system is limited and the large-area scanning and imaging efficiency of the Raman chemical imaging is low are solved; the food-borne pathogenic bacterium detection system based on the high spectrum has the advantages of convenience for utilization and obvious detection efficiency.

Description

technical field [0001] The invention relates to the detection technology of food-borne pathogenic bacteria, in particular to a hyperspectral-based food-borne pathogenic bacteria detection system and method. Background technique [0002] Food safety has always been an important issue of global concern. In recent years, food contamination incidents such as the "Listeria food poisoning" incident in the United States, the "hemorrhagic Escherichia coli" incident in Germany, and the "bacteria exceeding the standard" incident in quick-frozen dumplings in China have aggravated people's concerns about food safety. According to the estimates of the World Health Organization, billions of people around the world are infected with foodborne diseases every year, and foodborne diseases are a huge threat to contemporary global food safety. Therefore, how to quickly and accurately detect and identify foodborne pathogenic bacteria is an important task to effectively curb foodborne diseases a...
