摘要
A process for extracting bitter principle and tannin from hops, uses ethanol as the extracting agent in a single extraction. By controlling the water content of the ethanol used, the quantity of extracted tannin can be controlled. The tannin component can be separated out of the obtained extract as desired. By treating the extract with water vapor, all the alcohol can be simultaneously expelled and recovered. Ethanol is preferably removed and recovered from the resultant draff by means of the flash desolventizing system (FDS) method.
