Abstract
Changes in amino acids, organic acids and free sugars of soybean sprouts cultivated with extract of Glycyrrhiza glabra(GGE) during growth of 4 days were investigated. GGE was utilized as sprouting water of soybean and adjusted to 100 ppm, 200 ppm, 300 ppm and 400 ppm. Content of total amino acids of soybean sprouts cultivated with GGE was the most abundant, when soybean sprouts were cultivated for 3 days with 100 ppm of PGE. Content of aspartic acid was increased according to culturing days, but glutamic acid was shown to be a opposite trend. Content of total free sugar of soybean sprouts cultivated with GGE was lower than those of control group, and then increased by increasing of culturing days within GGE groups with same concentration. Sucrose of all groups during growth of soybean sprouts was decreased, but the other sugars were increased. Content of total organic acids was increased by increasing of culturing days and was the most abundant in soybean sprouts cultivated with 200 ppm of GGE among same groups. In conclusion, GGE as sprouting water of soybean was effective to increase of contents of amino acids and organic acids in soybean sprouts, indicating that GGE accelerated the quality of soybean sprouts.
감초추출물의 농도를 100 ppm, 200 ppm, 300 ppm and 400 ppm로 조절하여 콩을 발아시켜 재배한 콩나물의 아미노산, 유기산 및 유리당 함량을 재배 2일, 3일 및 4일째에 분석하였다. 총 아미노산 함량은 100 ppm에서 3일간 재배하였을 때가 가장 높았고, 또한 재배일수가 길어질수록 aspartic acid 함량은 증가하지만, glutamic acid 함량은 오히려 감소하는 경향을 나타내었다. 총 유리당은 GGE 콩나물의 경우 대조군에 비하여 낮은 함량을 나타내었으며, 그러나 재배일수가 증가할수록 그 함량은 많아졌다 Sucrose함량은 재배일수가 길어질수록 감소하였으나, 다른 유리당은 오히려 증가하였다 총 유기산은 재배일수가 증가할수록 많은 함량을 나타내었으며, 200 ppm으로 재배한 콩나물이 가장 많은 함량을 나타내었다. 결론적으로 감초추출물은 콩나물의 품질증진을 위한 아미노산 및 유기산 함량을 증가시키는 발아 및 재배수로서 효과적일 것으로 판단된다.
