대추의 연화현상을 연구하고자 건조중에 세포벽 구성성분의 변화를 조사하였다. 알코올 불용성 물질, 세포벽 및 수용성 물질의 함량은 건조 6일까지는 변화가 없었으나 건조 9일째에는 알코올 불용성 물질과 세포벽은 감소하였으나 수용성 물질은 증가하였다. 펙틴질과 헤미셀룰로오스는 건조 6일까지는 거의 변화가 없었으나 건조 P일째에는 펙틴질과 알칼리 가용성 헤미셀룰로오스가 감소한 반면 산가용성 헤미셀룰로오스는 증가하였다. 셀룰로오스는 건조 중에 증가하였다.

This paper was investigated to changes of cell components during drying for studies on the softening of jujube fruits. The contents of alcohol-insoluble material, cell wall and water-soluble material were not changed at 6 days of drying, but alcohol-insoluble materials and cell wall were decreased at 9 days of drying, however water-soluble materials were increased. Pectin and hemicellulose were not changed at 6 days of drying. Pectin and alkali-soluble hemicellulose were remarkable decreased at 9 days of drying, but acid-soluble hemicellulose was increased. Water-soluble pectin was not changed at 6 days of drying, but increased at 9 days of drying. EDTA-soluble and insoluble pectin were decreased after 6 days of drying. The non-cellulosic neutral sugars were not changed at 6 days of drying. The contents of arabinose, galactose and total neutral suger were decreased at 9 days of drying.
