Abstract

This study was conducted to analyze to the applicability of refined saps of Acer mono, A. mono for. rubripes, A. okamotoanum through sap refining system. 1 species of Bacillus genus, 3-4 species of yeast and 2 species of fungi were detected in the origin sap of three Acer spp. The pH in the origin sap were 6.5, and decreased in refining sap as 6.3-6.4. Sucrose in sugar components was detected in the origin and refining sap of Acer spp., but glucose and fructose were not detected. Compared the origin and refining sap, mineral components decreased slightly in refining sap. These results indicate that refining sap of Acer spp. are drinkable with long-term storage.

본 연구는 고로쇠나무, 붉은고로쇠나무, 우산고로쇠나무 수액을 대상으로 수액정제시스템을 활용하여 정제수액의 활용가능성을 분석하기 위하여 수행되었다. 세 수종의 고로쇠나무 수액 원액에는 Bacillus속 세균 1종과 효모 3-4종, 곰팡이 2종이 검출되었다. 수액의 pH는 수액원액이 6.5, 정제수액이 6.3-6.4, 당도는 원액이 1.67-3.05, 정제수액이 1.64-3.02로 약간 줄어들었다. 당 성분은 모든 수액에서 sucrose만 검출되었다. 수액 속의 미네랄 성분도 원액에 비해 정제수액에 비해 조금 줄어들었다. 이들 결과는 고로쇠나무류 수액을 정제하면 장기간의 보관과 함께 음용도 가능하다는 것을 시사한다.
