초록
가온재배한 한라봉감귤의 물리화학적 성분특성을 검토하였다. 수분 함량은 한라봉과 M16A에서 각각 87.42%와 88.12%, 총당은 8.01%와 7.81%, 산 함량은 1.09%와 0.99 %이었다. 비타민 C 함량은 한라봉과 M16A에서 각각 72.01와 68.01mg/100g으로 온주밀감에 비하여 매우 높았다. 무기물 함량 중에 K는 한라봉은 1369.33mg/100g으로 M16A의 938.33mg/100g에 비해 높았으며, 한라봉은 K > P > Ca > Mg > Na, M16A는 K > Ca > P > Mg > Na 순으로 높았다. 유리당 함량은 한라봉과 M16A에서 각각 sucrose가 3.60%와 4.36%로 전체의 절반을 차지하고 있으며, fructose와 glucose가 각각 2.22%와 1.90%, 1.94%와 1.65 %였다. 유기산은 citric acid가 전체의 69.88～82.32%를 차지하고 있었으며, 특히 M16A의 경우 malic acid 함량이 온주밀감에 비해 매우 높은 값을 나타내었다. flavonoid 함량은 품종간에 다소의 차이는 있었으나 다른 감귤류와는 달리 hesperidin과 narirutin이 주로 함유되어 있었다.
Abstract
Physicochemical properties of Hallabong Tangor (Citrus Kiyomi × ponkan) cultivated in heated greenhouse were investigated. Moisture contents of Hallabong and M16A (a variant species of Hallabong) were 87.42% and 88.12%, total sugar were 8.01% and 7.81%, and acid contents were 1.09% and 0.99%, respectively. Vitamin C content of Hallabong was 72.01mg/100g that was higher than Citrus unshiu. Potassium content of M16A was 938.33mg/kg, while Hallabong was 1369.33mg/kg. The contents of inorganic elements in a decreasing order were K > Ca > P > Mg > Na in Hallabong, and K > P > Ca > Mg > Na in M16A. Sucrose in Hallabong and M16A were 3.60% and 4.36%, respectively, which is half of total free sugars. Fructose and glucose Hallabong and M16A were 2.22% and 1.90%, 1.94% and 1.65%, respectively. Citric acid in Hallabong and M16A was 82.32% and 69.88%, respectively among total organic acids. The content of malic acid was higher in M16A, compared to Citrus unshiu. Hesperidin and narirutin were identified main flavonoids.
