Abstract

The red ginseng marc was roasted at various conditions and its organo-leptic properties and flavor components were investigated. Scorched-rice odor and roasted odor and the roasted red ginseng marc powder were much stronger than those from the unroasted red ginseng marc powder while earth odor, old-rice odor, metalic off-odor and woody odor were much weaker than those from the unroasted red ginseng marc. Savory odor and scorched-rice odor as well as savory taste and astringent taste from the water-extract of red ginseng marc roasted at $200^{\circ}C$ were stronger, but smoky odor, woody odor, biner taste and rough taste were weaker than those roasted at $230^{\circ}C$. Seven kinds of pyrazines, two kinds of carbonyl compounds, seven kinds of acids, two kinds of esters, five kinds of phenolic compowlds, maltol and six other compounds were identified as flavor components in distillate from red ginseng marc roasted at $200^{\circ}C$ for twenty minuties. Of them pyrazines and maltol are thought to be compounds which have characteristic odor such as roasted odor and/or scorchedrice odor in the roasted red ginseng marc.

온도와 시간을 달리하여 홍삼박을 볶음처리하여 얻은 분말과 수용성 추출액의 향기성분과 관능적 특성을 분석한 결과, $200^{\circ}C$에서 20분간 처리하였을 때 무처리 분말보다 정유성분의 양이 많았고, 향기성분은 7종의 pyrazin계 화합물을 비롯하여 29종의 화합물이 확인되었다. Panel에 의해 평가된 관능적 향미는 무처리구인 홍삼박 분말에서는 흙 냄새, 묵은 쌀 냄새, 비린내, 마른나무 냄새가 강하였으나, 볶음처리한 분말에서는 탄내, 구수한 냄새가 강하게 평가되었다. 볶음처리한 분말 $5\%$용액의 향은 무처리구에서는 비린내가 강하였으나, 처리구에서는 향기로운 냄새, 탄내, 누룽지 냄새, 마른나무 냄새가 강하였으며 비린내는 매우 약하게 평가되었다. $200^{\circ}C$에서 20분간 처리구에서 특히 커피와 같은 향미, 개운한 맛, 누룽지 냄새가 강했고, $2.5\%$ 용액에서는 개운한 맛, 떫은 맛이 강한 것으로 평가되었다. 볶음처리 시 생성된 이들 향미성분은 유리당과 aiginine함량의 급격한 감소에 의한 것으로 생각된다.
