Chinese Chestnut in Zhejiang: Variation of Nutritive Substances with Cultivar and Provenance

Eleven nut samples of Castanea mollissima composed of 4 cultivars and collected from 7 localities from Zhejiang were analyzed in terms of moisture content, reducing sugar, fat, protein, composition and content of amino acids, content of amylopectin and amylose, and shape and diameter of the starch grains. Results show that there is a positive correlationship between the content of protein and amino acids, between the content of fat and reducing sugar, and between the content of amylopectin and amylose, whereas a negative correlationship exists between the content of moisture and protein and amino acids, between the content of fat and amylopectin and amylose, and between the content of reducing sugar and amylopectin.
