板栗氨基酸的品种、地域差异及其营养价值分析

分析了浙江省７个产地栽培的４个主要板栗品种共１１个板栗样品的氨基酸组成和含量，同时探讨了其营养价值。对板栗中１７种氨基酸的分析表明，板栗几乎含有所有人体必需氨基酸。分析毛板红和魁栗的氨基酸，其组成极相似，且两者在地域上的差异较品种本身差异大。在所研究的几个地域中，浙南地区的板栗氨基酸含量高，浙东、浙西和浙北的氨基酸含量较为接近。此外，所有被测样品中，日本栗的蛋白质营养价值最低，二次结实板栗产最高。

Difference of Amino Acid in Castanea mollissima between Varieties and Yield Areas and Analysis On Its Nutrient Value

Kind and content of amino acid in 11 samples of Castanea mollissima from 4 main varieties growing in 7 regions were analysed, and their nutrient value was also discussed. The analysis showed that, Castanea mollissima almost contained all kinds of amino acid necessary for human body. Castanea mollissima cv.Maobanhong and Castanea mollissima were very similar in Kind of amino acid, and their difference between regions was larger than that between their varieties. Of all researched regions,amino acid content of Castanea mollissima in Southern Zhejiang was highest ; In Eastern Western and Northern Zhejiang, amino acid content was close. In addition ,of all tested samples, protein of Castanea crenata had the lowest nutrient value and double bearing Castanea mollissima was highest.
