Characteristics of Cell Walls in Melon Fruits Affected by Abnormal Fermentation

Abstract

|
This study was aimed to investigate the potential involvement of cell wall modifications with the occurrence of abnormal fermentation fruit in ´Gumssaragi-Eunchun´, (Cucumis melo L. var. makuwa Mak.). Cell wall components and structural changes were compared between pulp and placenta tissue of normal and abnormally fermented melon fruits, respectively.
Alcohol insoluble solid contents of both pulp and placenta tissue were higher in normal fruit. Total pectin content of fermented pulp were much lower but hemicellulose content was higher. However, such difference of pectin contents was not found in placenta. Although there was no great difference of net soluble pectin contents, the ratio of soluble pectins to total pectins were higher in fermented pulp. Cellulose content of pulp appeared to be higher than that of palcenta but no difference was found between placenta tissues.
Gel-filtration profiles of soluble pectins indicate that structural modification were undergone in fermented fruit. Interestingly, this modification of soluble pectins seems not to be associated with the increase of wall hydrolase activity such as polygalacturonase and β-galactosidase. In gel-filtration profile of hemicellulose showed no significant changes in elution pattern between normal and fermented tissue.
