Abstract
This study was performed to investigate the physicochemical properties of Korean Citrus sudachi fruit which were harvested at different harvesting time(every 20 days from Sep. 3 to Nov. 8) and region(Seogwipo and Cheju city area). The average weight of Citrus sudachi fruit harvested from Seogwipo area was as twice as that of Cheju area at the same period. The moisture content in fruit peel increased by ripening of fruit, but that of fruit juice showed no difference. The content of reducing sugar in fruit peel and fruit juice increased 2 times from Sep. 3 to Nov. 8. The content of crude fiber decreased both in fruit peel and fruit juice as progression of ripening. Crude protein and ash contents decreased in fruit peel but revealed no differences in the fruit juice during the same period. pH decreased in fruit peel and juice with its ripening. The content of vitamin C decreased by ripening of fruit. The transmittance which is important quality factor in fruit juice increased from Sep. 20 to Oct. 13. The content of free sugar increased about 2 times in fruit peel from Sep. 3 to Nov. 8 and showed 4 times increase in fruit juice at the same period. In the composition ratio of mineral, Ca and K were abundant in the fruit peel, but only K was the most abundant mineral in fruit juice than any others.
영귤을 이용한 다양한 가공제품의 개발을 위한 기초자료로 영귤의 과피와 과즙을 분리하여 수확시기별 (9월 3일부터 11월 8일까지 약 20일 간격) 및 산지별(서귀포, 제주시)에 따른 물리화학적 성분특성을 조사하였다. 영귤의 평균중량은 서귀포산이 제주시산보다 2배 이상이었으며, 평균직경도 10mm 이상 큰 것으로 나타났다. 과피의 수분함량은
