[0020] When conducting a study on the biological activity of food-derived polysaccharides, the sealing cover 2 is first removed from the open end of the sampling tube 1, and then the food sample is aligned with the cutting assembly for cutting. The cut food sample will fall on the partition 3. After cutting, the sealing cover 2 is re-covered, and then the sealing plug 6 is removed. The extract is added to the sampling tube 1 through the liquid filling port 5 to dissolve the polysaccharide from the food sample. After adding the extract, the sealing plug 6 is reinserted. After a period of extraction, the electric control valve is opened, and the solution flows along the pipe 4 to the filter assembly for filtration. The filtered solution will enter the storage assembly for storage. It should be noted that a control knob can be set on the sampling tube 1. When the knob is selected, an electrical signal is sent to control the opening and closing of the electric control valve. At the same time, a built-in rechargeable battery can be set in the sampling tube 1 to provide power for the electric control valve, wherein a sealed conductive interface can be used to connect the battery and the electric control valve. Preferably, the upper surface of the partition 3 is inclined toward the pipe 4.
[0021] As a preferred embodiment, the cutting assembly includes an annular blade holder 7. A mounting slot 8 is defined downwardly on the open sidewall of the sampling tube 1. The annular blade holder 7 is inserted into the mounting slot 8. Several blades 9 are fixedly connected to the annular blade holder 7.
