본 연구는 알칼리수를 이용한 홍삼추출물의 품질특성을 조사하였다. 알칼리수의 미네랄 함량은 칼슘이 로 가장 높았으며, 이온화 무기염류의 첨가량이 높을수록 알칼리도는 증가하는 것으로 나타났다. AKRGE 3, 6 및 9의 pH는 , 당도 , 가용성 고형분 , 갈색도 3.0으로 나타났으며 RGE와 큰 차이는 없었다. AKRGE 6과 AKRGE 9의 칼슘함량은 107.80 mg% 및 171.81 mg%로, RGE와 시판 홍삼 파우치 제품 5종에 비해서
This study investigated the quality characteristics of red ginseng extracts prepared using alkaline water. The principal extract mineral was calcium, at 61.73-180.63 mg%, and alkalinity increased as the ionization minerals concentration rose. Alkaline red ginseng extracts(AKRGEs) 3, 6, and 9 were found to have pH values of 4.9-5.0, to be of 3.03-3.43 degrees of , with soluble solid contents of 2.33-2.60%(w/v). Extract 3 was brown in color, thus similar to that of(conventional) red ginseng extract(RGE). The calcium contents and alkalinity levels of AKRGE 6 and AKRGE 9 were approximately 18-29-fold and 5-11-fold higher, respectively, than those of RGE and five commercial samples of red ginseng. AKRGEs showed lower crude saponin contents than did RGE, but ginsenoside contents did not differ significantly between RGE and AKRGEs. The DPPH-assayed free-radical and superoxide radical scavenging activities of AKRGEs were 12-13% and about 20%, respectively, thus similar to those of RGE. In sensory evaluation tests, AKRGE 3 and 6 were less bitter and better in overall quality than was RGE.
