[0002] Biogenic amines are a class of low-molecular-weight compounds with biological activity and amino groups. Most foods contain biogenic amines. These biogenic amines are mainly produced by the decarboxylation of amino acids by microbial amino acid decarboxylase. A moderate amount of biogenic amines can promote normal physiological activities of the human body, while excessive intake will produce adverse reactions. Therefore, it is necessary to take samples of food for testing, and the samples need to be weighed during sampling to avoid taking too much or too little.

[0003] At present, the Chinese utility model with the announcement number CN216846514U discloses a food weighing device, which relates to the field of food processing technology.
