단감재배농가에서 전량 폐기되는 적과단감을 이용한 가공식품을 개발하기 위한 기초자료를 얻고자 일반성분, 유리당, 유기산, 무기질 및 비타민 등을 분석하였다. 일반성분은 수분이 89.08%로 대부분을 차지하였으며 회분이 0.26%, 조지방이 0.56%. 조단백질이 0.75%이었다. 유리당은 glucose와 fructose가 각각 3.34%, 3.01%로 대부분을 차지하였으며 sucrose는 미량 검출되었다. 유기산은 citric acid, maleic acid, fumalic acid, lactic acid 등이 검출되었으며 그 중 lactic acid가 68.65㎎%로 전체 유기산 함량의 79%를 차지하였다. 무기질은 K, P, Na. Ca, Fe, Zn 등이 검출되었으며 그 중 K이 126.l2㎎%로 대부분을 차지하였으며 Fe과 Zn은 미량 검출되었다. 비타민 A는 33.95 R.E.로 완숙단감보다 함량이 적었으며 비타민 C는 171.01㎎%로 완숙단감에 비해 10배 이상 함유하였으며 비타민 B_l과 B_2는 소량 검출되었다.
To develop a new processed foods with prepersimmon, the contents of approximate composition, free sugar, organic acid, mineral and vitamins in prepersimmon(Diospyros kaki Thumb. cv. Fuyu) were investigated. The approximate composition was 89.08% of moisture, 0.26% of crude ash, 0.56% of crude fat and 0.75% of crude protein respectively. Free sugars were composed of glucose, fructose and sucrose. Glucose(3.34%) and fructose (3.01%) were major free sugars, and sucrose was detected a small quantities. The organic acids were composed of citric acid, maleic acid, fumalic acid and lactic acid. Lactic acid (68.65㎎%) was major a organic acid and took 79% of total organic acid amount. Minerals were K, P, Na, Ca, Fe and Zn, and K was a major mineral and detected 126.12㎎%, and Fe and Zn were a small quantities, The content of vitamin A was 33.95 R.E., and less than that in hard persimmon, and the content of vitamin C was 171.01 ㎎%, 10 times higher in comparison with that in hard persimmon, and vitamin B_1 and B_2 were detected a small quantities.
