Abstract

본 발명은 용매를 재사용하는 스테비오사이드의 결정화 방법에 관한 것으로, 좀 더 상세하게는 메탄올에 30%(W/W)의 농도로 원료스테비오사이드를 현탁시키고 1~24시간 결정화시킨 후 원심분리기를 이용하여 결정화물과 상등액을 분리하고 여기서 분리된 상등액을 재사용하여 1-3시간동안 원료스테비오사이드 양 20-30%를 현탁시키고 1차 결정화시킨 후 다시 원심분리를 거쳐 얻어진 상등액으로 2차 결정화를 진행시키는 것으로 이루어진 용매를 재사용하는 스테비오사이드의 결정화 방법에 관한 것이다.The present invention relates to a crystallization method of steviosides for reusing a solvent, and more particularly, by suspending the raw stevioside at a concentration of 30% (W / W) in methanol and crystallizing for 1 to 24 hours using a centrifuge. The crystallization and the supernatant are separated, and the supernatant is reused to suspend 20-30% of the raw stevioside for 1-3 hours, first crystallize and then undergo secondary crystallization with the supernatant obtained through centrifugation. A method for crystallizing steviosides which reuses a solvent consisting of:
