Abstract
This study was carried out to quantitate the proximate composition of free sugars, amino acids, fatty acids, and minerals contents in Jehotang. The analysis of overall chemical components of Jehotang indicates that it contains 22.40% of moisture, 1.31% of crude protein, 1.24% of crude fat, 0.80% of ash and 74.25% of carbohyderate. The pH of the Jehotang was 3.2. The sugar content was relatively high. Among the identified extractable free sugars were 15.3% of fructose, 13.6% of glucose, 0.42% of sucrose, 1.18% of maltose, and a trace of isomaltose. No raffinose, maltotriose and molezitose were detected. In amino acid composition of the Jehotang, leucine was the highest with the content of 9.6mg, followed by arginine, valine, and phenylalanine. The ratio of essential/total amino acid was 40.4%. Fatty acid content, which occupies 1.24%, can be classified into 4 kinds. Major ones, in order of quantity, are oleic acid(52.7%), linoleic acid(28.5%), palmitic acid(14.6%) and stearic acid(4.2%). Among the minerals, the amount of K was the highest with the level of 2430.5ppm, followed by Ca, Na, P, Mg, Fe, Mn, Zn and Cu.
제호탕의 화학성분을 분석한 결과는 다음과 같다. 제호탕의 일반성분으로는 수분 22.40%, 조단백질 1.31%, 조지방 1.24%, 회분 0.80%를 그리고 탄수화물은 74.25% 를 나타내었다. 한편 pH는 3.22로 나타났다. 총 유리당이 31.5%로 비교적 많은 당이 함유되어 있었고 유리당함량은 fructose 15.3%, glucose 13.6%, sucrose 0.42%, maltose 1.18%였으며 isomaltose가 미량 함유되는 것으로 추정 되었고 그밖에 raffinose, maltotriose, molezitose는 검출되지 않았다. 제호탕의 아미노산 조성은 leucine이 9.6mg으로 가장 높은 수치를 나타냈으며 arginine, valine, phenylalanine 등의 순이었다. 총 아미노산에 대한 필수아미노산의 비율은 40%이었다. 지방함량 1.24% 중 이를 구성하는 지방산은 palmitic acid 14.6%, stearic acid 4.2%, oleic acid 52.7%, linoleic acid 28.5%를 차지하고 있었다. 금속의 함량은 칼슘(Ca) 582.7ppm, 마그네슘(Mg) 174.4ppm, 아연(Zn) 5.2ppm, 인(P) 252.2ppm, 망간(Mn) 7.9ppm, 나트륨(Na) 404.0ppm, 철(Fe) 56.4ppm, 칼륨(K) 2430.5ppm, 구리 (Cu) 2.6ppm이었다.
