초록

고로쇠수액의 채취시기별 이화학적 특성 및 영양성분을 분석하였다. 고로쇠수액의 갈변도 및 탁도는 채취시기가 늦어질수록 증가하는 경향을 보였으며, pH 및 총산도는 큰 차이가 없었다. 유기산은 citric acid 및 malic acid가 검출되었으며, citric acid는 채취시기가 늦어질수록 감소하는 경향을 보였고 malic acid는 증가하였다. 유리당은 sucrose와 fructose 및 glucose가 검출되었으며, sucrose는 채취시기가 늦어질수록 감소한 반면, fructose는 증가하였고 glucose는 채취시기 후반기에만 검출되었다. 조단백질과 조회분은 채취초중반기에는 변화가 없었으나, 후반기에 많은 증가를 보였다. 무기성분은 Ca, Cu, Fe, K, Mg 및 Mn 등이 검출되었으며, K, Mg 및 Fe는 채취기시가 늦어질수록 증가하였다. 이상의 결과로부터 채취시기 후반기에 채취되는 고로쇠수액은 탁도의 증가로 인하여 음용하기 어렵지만, 조단백질, 유기산, 무기성분 등의 증가로 영양적으로 우수할 것으로 판단되므로 적절한 가공방법을 이용하여 탁도를 제어한다면 이용률 향상에 도움이 될 것으로 판단된다.

This study evaluated the physicochemical characteristics and nutritional components of Goroshoe (Ace rmono Max.) sap related with collection periods. The changes of browning index, turbidity, pH, total acidity, organic acids, free sugar, crude protein, crude ash, and minerals were investigated. Browning index and turbidity were slightly increased, while pH and total acidity were not changed as collection periods increased. Citric acid decreased slightly from 0.081 to 0.045 mg/mL at middle collection periods. Malic acid also decreased from 0.494 to 0.416 mg/mL at middle collection periods but then afterward increased to 0.674 mg/mL as collection periods increased. Sucrose decreased from 1.759 to 1.000%, while fructose increased from 0.023 to 0.044% as collection periods increased. Crude protein increased remarkably from 0.80 to 17.49 mg% as collection periods increased. Crude ash decreased slightly from 0.04 to 0.03% at middle collection periods, and then increased afterward to 0.06% as collection periods increased. Potassium increased from 13.43 to 49.75 mg/L as collection periods increased. These results indicate that the useful components of Goroshoe sap increased with increasing collection periods, but turbidity could be reduced.
