Abstract
To efficiently utilize not only fresh chestnut(FC) but also wormy chestnut(WC), four types of chestnut starches which were fresh chestnut starch(FCS), fresh chestnut crude starch(FCCS), wormy crude starch(WCS) and wormy chestnut crude starch(WCCS) were extracted from them, respectively. The mooks were prepared with four types chustnut starches and a acorn crude starch(ACS) as control. Sensory evaluation by five points method indicated that the mooks had noticeable differences in smoothness, taste and fragrance, and no noticeable differences in color and texture. The total scores of mooks for sensory evaluation were higher in order of FCS, FCCS, WCS, ACS. Retrogradation properties for the chestnut mooks prepared by five type starches which were FCS, FCCS, WCS, WCCS and FWCCS(mixing FCCS and WCCS with same weighs) were also investigated with the variation in the starch concentration, storage time and storage temperature by hardness of textural properties. The results indicated that when the mooks which were prepared with starches(all but FWCCS), concentration 8% and 10% were storaged for 7 days at 15$^{\circ}C$, there were no variations in the qualities (hardness) of the chestnut mooks.
