Outline of Final Research Achievements

In the present study, trial for improvement of fruits’ flavor by hyo-on storage, caused by polysaccharide degradation, was done. In polysaccharides, I focused on change of fractan especially.In the stored fruits, watermelon showed the notable elevation of sweet taste evaluation with the elongation of storage time. At the same time, as fractan content was decreased, degraded fractan is speculated to contribute for elevated sweet taste. Anti-oxidative ability and lower molecular weight fraction fractionated by size excluded chromatography were increased with storage time. Thus they might have correlation with each other.Those results proved practical effect for improvement of fruit flavor by hyo-on storage.
