Abstract
The invention relates to a method for extracting tannin from tara legume in water or ethanol through microwave radiation with a certain strength. The method includes radiating tara bean flour and water or ethanol at solid to liquid ratio of 1:4-10 with a microwave strength of 15-45 W/L for 30-120 min. for extracting at 40-80 DEG C at a stirring rate of 40-80 rpm, centrifugally separating or vacuum filtering, and collecting the filtrate, i.e., tara tannin solution. The tara bean flour is radiated with microwave to allow tannin polar molecule in the tara bean flour to rapidly enter into the leaching solution. The extraction rate of the tara tannin is greater than 70%. Compared with the conventional cooking method, the microwave extraction method of the tara tannin has the advantages of simple process, high extraction efficiency, energy saving effect, advanced process, high efficiency, short period, good economic and operability.
