Abstract:

To investigate pesticide residues, heavy metals content, and nutritional indicators in Agrocybe aegerita, systematic analysis and determination were conducted on the safety indicators and basic nutritional quality of 167 batches of dry samples and fresh samples of Agrocybe aegerita from different origins. The results showed that a total of 41 pesticide residues were detected in Agrocybe aegerita samples, including three banned pesticides. Sulfur dioxide contents in all samples did not exceed the maximum residue limit. Cadmium pollution was widespread in the tested samples, but the cadmium content in the experimental samples did not exceed the maximum residue limit. Except for protein, there were no significant differences in moisture, polysaccharides, crude fat and ash content among dry samples of Agrocybe aegerita from different origins; 16 amino acids, including 7 essential amino acids, were detected in all Agrocybe aegerita samples, and there were certain differences in amino acid contents of Agrocybe aegerita from different origins.

Key words: Agrocybe aegerita, safety indicator, nutritional quality, origin
