청과물의 품질 영양표시 모델을 개발하기 위하여 경북의성군 옥자두를 대상으로 품질 및 영양적 성분을 분석하고 품질 영양표시 모델을 확립하였다. 일반성분은 수분 92%, 조단백 0.74%, 조지방 0.64%, 조섬유 1.65%, 조회분 0.32%, 무질소물 4.29%로 확인되었으며, 열량은 32kcal/100g 으로 계산되었다. 당도는 로, 산도는 로 나타났으며, 자두의 비타민 C 함량은 로 나타났다. 무기질은 황, 칼륨, 칼슘, 나트륨, 마그네슘
In order to develop a model on the quality and nutrition label of Korean fruit plum, we first examined the quality and nutritional characteristics of Korean Plum, ChooHee. The contents of moisture, crude protein, crude fat, crude fiber, crude ash and N-free extinct were 92% 0.74% 0.64% 1.65%, 0.32% 4.29% respectively. Thus the total calorie of the sample was 32 kcal/100 g. The content of sugar, acidity and Vitamin C were , and respectively. The principle minerals were S, K, Ca, Na, and Mg. Major free sugars were fructose, glucose and sucrose and major organic acid were succinic acid, malic acid and citric acid. The difference of contents of total phenols between peel and flesh pare were considerable. The total phenolic contents of whole fruit were . On the above results, the quality and nutrition label of Korean plum were developed in the first time. We expect that this study on labeling could play an important role to the quality control and marketing of Korean agricultural products.
