Effect of Clarification by Ethanol on Physicochemical Properties of Red Ginseng Extract
에탄올에 의한 청징이 RG-Ext.의 이화학적 특성에 미치는 영향
- Published : 1991.02.01
Abstract
To determine optimum ethanol concentration and clarification time in ethanol clarification of red ginseng extract(RG-Ext), physical properties, crude saponin recovery of clarified RG-Ext. and stability of red ginseng drink prepared from clarified RG-Ext. were investigated.
Color intensity, redness(a value), viscosity and yield of clarified RG-Ext. were decreased in proportion to the increase of ethanol concentration and clarification time, but transmittance, brightness(L value) and yellowness (b value) were decreased.
Crude saponin recovery of clarified RG-Ext. were not change significantly by the increase of ethanol concentration.
Red ginseng drink prepared from 50-90% ethanol clarified RG-Ext. were stable without precipitation until six months at the storage of
