Chemical composition of fruits of some important chestnut cultivars

Abstract

In this study, chemical compositions of the fruits of some important domestic chestnut types and cultivars were investigated. They contained (g/100g dry matter basis) total carbohydrates 75.32 - 86.31, total sugar 10.32 - 22.79, invert sugar 0.08 - 1.25, starch 54.45 - 69.70, sucrose 8.86 - 21.28, ash 1.02 - 3.22, crude cellulose 3.58 - 5.96, total fat 0.49 - 2.01, total protein 4.88 - 10.87. Ca, Mg, Fe, Mn, Cu, Zn, P, Na and K contents were (mg/100g) 43 230, 70 - 160, 0.4 - 5.7, 0.7 - 5.5, 0.6 - 3.8, 1.8 - 9.1, 107 - 191, 6 - 41, 761 - 1271, respectively.
