Abstract:
In order to study the nutrients components and the processing adaptability of different varieties Chinese chenstnut, there chestnut samples (oil chestnut from Macheng in Hubei province,oil chestnut and wind chestnut from Yangshan in Guangdong province) were analyzed. The results showed that the three kinds of chestnut had little difference in nutrient components. Macheng oil chestnut with 59.5% water content was suitable for pulping. Yangshan oil chestnut had large grain with weight value of 16.53 g. Macheng oil chestnut and Yangshan wind chestnut had higher edible rate. Small difference was observed in characters of chestnut starch from different sources. The solubility and swelling power of the tested chestnut starch were closer to 50% and about 30% at 95 ℃. The starch of Yangshan oil chestnut had higher solubility and swelling power than that of the others. Considering the transparence of the starch, Yanshan oil chestnut was better than the others. All tested chestnut showed high freeze-thaw stability.
