Abstract: OBJECTIVE To study and compare the effect of the drying methods on the content of aflatoxins in Euplyphaga Steleophaga. METHODS Living Euplyphaga Steleophagas were boiled to death. Simulating the dry conditions of producing area, set up a part of samples dried at 30℃; another samples dried at 60℃ quickly(2 batches per group). According to the pharmacopoeia, the contents of aflatoxins in two group of samples were detected by HPLC(fluorescence detection). RESULTS The samples drying at 30℃ had obvious stench, the content of aflatoxins exceeded standard hardly. The samples drying at 60℃ quickly had slightly gamey smell, the content of aflatoxins was qualified. By comparison with traditional naturally dried samples, the samples dried 12 h at 65℃ from a supplier, the content of aflatoxins was qualified. CONCLUSION The content ofaflatoxins in Euplyphaga Steleophaga can be controlled through timely drying at higher temperature.
