Objective: To analyze the processing situation of 124 batches of scorpions and optimize the salt-water processing.Methods: The character, extract, moisture, total ash, acid insoluble ash, amino acids content and heavy metals in the marketed scorpions were determined.Using extract and amino acids contents as the indices, the salt-water processing was optimized.Results: The results of the above determinations showed that the quality difference was very obvious for the marketed scorpion, and the extract and amino acids contents were the highest in scorpion boiled in 2% sodium chloride aqueous solution for 5 min.Conclusion: The item of extract test should be revised in the current standard, and the items such as moisture, total ash, acid insoluble ash, amino acids content and heavy metals should be taken into consideration in order to control the quality of scorpion more comprehensively.The best salt-water processing of scorpion is boiled in 2% sodium chloride aqueous solution for 5 min.
