Abstract

Glucose, arabinose and total non-cellulosic neutral sugar contents of alcohol-insoluble substance were increased during maturation of persimmon, but arabinose, galactose and total non-cellulosic neutral sugar contents were decreased in soft persimmon. The main non-cellulosic neutral sugars of cell wall were galactose, arabinose and glucose. Arbinose and galactose contents were decreased during maturity and this tend was remarkable in soft persimmon. Pectic fraction contained $70{\sim}82%$ of uronic acid, and galactose, arabinose and uronic acid of pectic fraction were decreased. The main non-cellulosic neutral sugars of hemicelluloses were glucose, xylose, and galactose. Galactose was decreased during maturation and postharvest, and contents of non-cellulosic neutral sugar were decreased in soft persimmon.

감과실의 성숙중 알콜 불용성 물질의 glucose, arabinose 및 총 비섬유성 중성당의 함량은 증가하였으나, 연시에서는 감소하였다. 세포벽을 구성하는 주요 비섬유성 중성당은 galactose, arabinose, glucose이었고, arabinose와 galactose는 성숙과 연화중에 감소하였다. Pectin질은 uronic acid가 $70{\sim}82%$ 정도 차지하였으며 uronic acid, galactose, arabinose는 성숙과 추숙중에 감소하였다. Hemicellulose의 주요 중성당은 glucose, xylose, galactose이었고, 성숙과 추숙 중 특히 galactose가 감소하였으며 연시에서는 대부분의 구성당이 감소하였다.
