The invention discloses a detection device and a detection method for the quality of white kidney beans. According to the detection method, the qualified white kidney beans are divided into m white kidney bean samples with the same mass; a sensor array is used for detecting each sample in sequence to obtain m signal to noise ratio peak values; a computer is used for calculating an average value of the signal to noise ratio peak values and defining the average value of the signal to noise ratio peak values into a threshold value Thr; a white kidney bean sample W to be detected is detected to obtain a signal to noise ratio peak value sigma of the white kidney bean sample W; a non-linear self-calibration dynamic cataloging model is used for calculating a dynamic cataloging parameter delta of the white kidney bean sample W; the computer is used for judging whether the white kidney beans is qualified or not. The detection device and the detection method disclosed by the invention have the characteristics of accurate and rapid detection, good economical efficiency and capability of providing reliable data support for producing food by using the qualified white kidney beans.
Description
technical field [0001] The invention relates to the technical field of grain quality detection, in particular to a white kidney bean quality detection device and detection method that can accurately and quickly detect whether the white kidney bean is spoiled. Background technique [0002] Food safety is an important factor affecting human health, and has always been the focus of research by relevant departments around the world. White kidney beans are rich in protein, carbohydrates and other ingredients, and are food crops with high nutritional value. However, during the storage of white kidney beans, various molds such as Aspergillus flavus, Aspergillus parasiticus, Aspergillus fusarium, and Aspergillus penicillium can be produced, which can easily cause mildew in a humid environment, releasing musty, rotten, rancid and other odors. Once the white kidney beans enter the circulation market, harmful food will be produced, which will seriously endanger people's health. [00...
