Abstract
The clarified apple juice was pre-concentrated by reverse osmosis system as a trial for reduction of heat treating time and quality drop in concentration of the juice. The permeate fluxes through CA 865 and CA 960 membranes were higher than those of HR 95 and HR 98 membranes even at the low operating pressure. In the concentration limit depended on the membranes used, HR membranes operated at 60 bar showed
청징한 사과쥬스를 역삼투 장치를 이용하여 예비농축을 하였다. 사용한 역삼투막의 종류에 따른 농축한계농도는, HR 95 및 HR 98형의 역삼투막에 60 bar를 가하여 농축하였을 때
