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. Amylose content of FCS(46.5%) and water binding capacity of FCCS(103.0%) were higher than those of othe three, respectively. Swelling powers of all sample starches increased rapidly from 6$0^{\circ}C$ to 8$0^{\circ}C$. Solubilities showed the same pattern as the swelling powers. In the textural properteis investigated with IUTM(instron universal testing machine), hardnesses and elasticties of chestnut starches were 50~58I.U. and 14~16I.U., respectively. The results of textural evaluations showed that it was possible to prepare chestnut mook with FCS, FCCS and WCS.
