인삼추출물(100∼400 ppm)로 콩을 발아시켜 4일간 재배한 콩나물의 생육특성, 아미노산, 유기산 및 유리당 함량의 변화를 조사하였다. 인삼추출물은 콩나물의 길이 및 무게증가에 효과적이었다. 총 아미노산 함량은 100 ppm에서 3일간 재배하였을 때가 가장 높았고, 추출물의 농도가 높을수록 그 함량이 많아졌다. 또한 재배일수가 길어질수록 aspartic acid 함량은 증가하지만, glutamic acid 함량은 오히려 감소하는 경향을 나타내었다. 총 유리당은 재배일수가 증가할수록 많아졌으나, 농도별로는 일정한 경향이 나타나지 않았다. Sucrose는 대조구에서 점진적으로 감소하였고, 추출물 처리구는 3일까지는 증가하다가 그 이후는 감소하였으며, 다른 유리당은 4일까지 지속적으로 증가하였다. 총 유기산은 인삼추출물 200 ppm으로 발아시켜 3일 동안 재배한 콩나물이 가장 많은 함량을 나타내었다. 그 중에서 phytic acid가 가장 많았으며, 총 유기산의 45∼60% 정도를 차지하였다. 결론적으로 인삼 추출물을 콩의 발아액으로 활용하면, 콩나물의 성장촉진, 아미노산, 유기산 및 유리당 함량의 증진에 효과가 있는 것으로 나타났다. Changes in weight, length, amino acids, organic acids and free sugars of soybean sprouts germinated with extract of Panax ginseng(PGE, 100∼400 ppm) were investigated. PGE increased the weight and length of soybean sprouts. Content of total amino acid in soybean sprout germinated at 100 ppm of PGE after cultivation for 3 days was the most abundant and then decreased by increasing the concentration of PGE. Content of aspartic acid was increased with culture time, but that of glutamic acid was shown to be an opposite trend. Content of total free sugar was increased by increasing culture time and not affected by concentration of PGE. Content of sucrose in control group during growth of soybean sprout was decreased, but sucrose contents in PGE groups were increased to 3 days and decreased thereafter. However, the other sugars were continuously increased for 4 days. Content of total organic acids was the most abundant in soybean sprouts germinated with 200 ppm of PGE and cultured for 3 days. Phytic acid was a major organic acid, showing the range of 45 to 60% for total organic acids. In conclusion, PGE as sprouting water of soybean was effective to increase of growth, contents of amino acids and organic acids in soybean sprouts, indicating that PGE accelerated the quality of soybean sprouts.
