[0002] Food detection is a key step to ensure food safety, which involves analyzing and evaluating various harmful substances in food to protect consumers from foodborne diseases and poisoning. During food detection, the collected samples often need to be ground, and the grinding degree of food detection samples usually needs to be determined according to specific detection items and analysis methods. Generally speaking, the sample should be ground to a fine enough degree to ensure the accuracy and representativeness of the detection results.
