In order to study the pollution condition of TTX in aquatic products, the tissue with high TTX content is required to be selected to extract the TTX, and the extracting solution is separated and purified.
At present, the extraction of TTX mainly comprises a microbial fermentation method and a biological tissue extraction method, wherein TTX produced by microbial fermentation is only at ng level, the yield is low, and large-scale production cannot be performed, so the biological tissue extraction method is a commonly used extraction method at present, and the specific steps are as follows: extracting sample (such as liver, ovary, etc.) with high toxin content with proper ratio and temperature, leaching with acetic acid water solution or acetic acid organic solvent for proper times until most of toxin in tissue is dissolved, and separating and purifying. In order to increase the dissolution rate of TTX, the extracted sample needs to be homogenized in advance of leaching. The extracted samples are crushed and homogenized by a household meat grinder, and the household meat grinder has the following defects: (1) The stability is poor, and a cup body or a hand-held machine body which needs to be held by a hand has certain potential safety hazard; (2) When stirring, the sample in the cup body can be thrown to the cup wall under the condition that the blade rotates rapidly, so that the sample at the cup wall is gradually piled up and the height is gradually increased, the height of the sample in the middle is reduced, the blade cannot contact the sample at the cup wall, and the homogenization effect is poor; (3) the height of the blade cannot be adjusted.
