Abstract

The purpose of this study is to find out the optimal mixing ratios of three different amount of red ginseng powder(0, 5, 10%), water(12, 16, 20%) and sugar(4, 8, 12%) per weight of glutinous rice powder. The microbial count increased with increasing moisture content. The microbial count has decreased in 10% addition group though the microbial count according to the red ginseng powder addition did not have a difference the having mind in 5% addition group. Control group(the red ginseng powder no addition) showed an exponential increase in the change in hardness according to the amount of the red ginseng powder addition 24 hours after(except the moisture addition amount 20%). However, the change in devotion hardly appeared without the relation in moisture and the amount of the sugar addition in the addition group of the red ginseng powder 5%. Moreover, the change in hardness besides the moisture addition amount 12% hardly appeared also in the addition group of the red ginseng powder 10%. It has been understood that the red ginseng powder addition 5% crowd smells, and the taste and the color are suitable though it was clarified to the red ginseng powder addition 10% crowd that a peculiar smell taste and taste to the red ginseng are very strong by the sensory inspection. In conclusion, according to its microbial count, texture and sensory analyses, the optimal Injulmi formulation consisted of red ginseng powder, water and sugar were 5, 16 and 8%. The results suggested that red ginseng powder is effective in increasing the self life of Injulmi.

본 연구의 목적은 홍삼 분말(0, 5, 10 %), 물(12, 16, 20 %), 설탕(4, 8, 12 %)의 첨가량을 달리하여 최적의 배합비를 찾기위하여 실시하였다. 인절미 제조에 있어서 수분 첨가량이 증가할수록 생균수는 증가하였다. 홍삼가루 첨가에 따른 생균수는 5% 첨가군에서는 유의적인 차이가 없었지만 10% 첨가군에서는 생균수가 감소하였다. 홍삼 첨가량에 따른 굳기의 변화는 홍삼 무첨가군은 수분첨가량 20%를 제외한 실험군에서 24 hr이후에 급격한 증가를 나타내었다. 그러나 홍삼 5% 첨가군에서는 수분 및 설탕 첨가량에 상관없이 굳기의 변화가 거의 나타나지 않았다. 또한 홍삼 10% 첨가군에서도 수분 첨가량 12% 이외에는 굳기의 변화가 거의 나타나지 않았다. 관능검사에서 홍삼 첨가 10%군은 홍삼 특유의 향미와 맛이 너무 강한 것으로 나타났으나, 홍삼 첨가 5%군은 향, 맛, 색이 적당한 것으로 나타났다. 생균수 측정, 조직감 측정과 관능검사의 결과에서 홍삼인절미의 최적의 배합비는 찹쌀가루에 대해 홍삼가루, 수분, 설탕이 각각 5, 16, 8%로 나타났으며 홍삼가루 첨가는 인절미의 저장성 향상효과가 있었다.
