| description | The invention discloses a preparation method of modified tannin extract particles. The preparation method comprises the following steps: crushing Chinese chestnut thorn shells and sieving, and adding sodium bentonite to perform water leaching; filtering a leaching liquid obtained in the first step, and concentrating a filtrate to obtain a concentrated liquid; adding starch and a surfactant in the concentrated liquid obtained in the second step under stirring to obtain an emulsion; and concentrating the emulsion obtained in the third step again, and then performing spray drying to obtain granular modified tannin extract materials. When the prepared tannin extract particles disclosed by the invention are applied to light leather tanning, the tanning performance can be improved, the leather grain surface can be improved, and the feeding times of tannin extract tanning materials can be reduced on the premise that the tanning quality is ensured. |
