Fuji 과실의 성숙에 따른 pectin 질의 변화를 조사하기 위하여 LMP (low methoxy pectin), HMP (high methoxy pectin) IAP (ionically associated pectin), CBP (covalently bounded pectin), methoxyl 및 구성당의 함량변화와 DE(degree of esterification)를 조사하였다. 그 결과 LMP+HMP와 IAP+CBP는 AIS(alcohol insoluble solid)의 각각 70%, 22%를 차지하였고 이들 성분은 성숙에 따라 다소 증가하였다. Pectose 질을 구성하는 중성당중 hexose는 LMP, HMP, IAP, CBP 다같이 $20{sim}50%$가 감소하였는데 특히 Gal의 감소율은 63%이었다. Pentose는 $1{sim}9%$가 증가하였고 uronic acid는 $2{sim}4%$감소하였다. 그러나 HMP, CBP에서는 uronic acid의 상대적 함유비율은$3{sim}5%$ 증가되었다.
The changes of methoxy content. compositional sugars. degree of esterification (DE) and pectic substances such as LMP (low methoxy pectin), HMP (high methoxy pectin) IAP (ionically associated pectin) and CBP (covalently bounded pectin) of Fuji apple were investigated during maturity. The contents of LMP+HMP and IAP+CBP in alcohol insoluble solid(AIS) were 70% and 20%. respectively. These pectic substances were increased slightly during maturity. The reductions of hexose and uronic acid were Iron 20-50% and from 2-4%, respectively, but the inclosed of pentose was from 1-9% in LMP, HMP, IAP and CBP during maturity of Fuji apple. The galactose was decreased significantly among hexose. Whereas the relative ratio of uronic acid in HMP and CBP was increased.
