Changes of Texture in terms of the Contents of Cellulose, Hemicellulose and Pectic Substances during Fermentation of Radish Kimchi

The changes of dietary fiber and texture of radish Kimchi fermented at were investigated. During the fermentation period, hardness and brittleness of radish Kimchi were decreased. The changes were more marked in the brittleness. But the contents of cellulose and hemicellulose were not changed considerably. The contents of AIS was decreased with fermentation. During the fermentation, hot soluble pectin was increased and protopection was decreased but the amount of changes was small. The texture of radish Kimchi was affected by contents of pectic subsrances, especially protopectin. The coefficient of correlation between hardness and protopectin contents was 0.85.(=r)
