초록

This paper was carried out to investigate changes in cell wall, cell wall polysaccharides, pectic substances extracted from cell wall of persimmon fruits treated with polygalacturonase and $\beta$-galactosidase in vitro. Degrading degree of cell wall treated with cell wall-degrading enzymes were higher in order polygalacturonase, polygalacturonase+$\beta$-galactosidase and $\beta$-galactosidase. Contents of soluble pectic substances in cell wall treated with cell wall-degrading enzymes showed as the same order as degrading degree of cell wall, while contents of insoluble pectin lower. Contents of versene-soluble pectin and total pectic substance were not affected by cell wall-degrading enzymes. Contents of uronic acid and hexose in soluble material isolated from cell wall treated with polygalacturonase and mixed enzyme were higher than those of untreatment and $\beta$-galactosidase treatment.
