我国不同主产区核桃品质综合评价分析

为了探究我国不同主产区核桃品质差异,选择10个有代表性的云南核桃样品及12个其他产区普通核桃样品进行核桃青皮、仁、分心木中主要营养成分分析与评价。测定了核桃青皮中的黄酮、单宁和胡桃醌含量,核桃仁中粗蛋白、粗脂肪、维生素E、褪黑素、磷脂和氨基酸总量及分心木中的粗脂肪、粗蛋白、黄酮和氨基酸总量。对不同主产区核桃品质进行了主成分分析。结果表明:云南主栽的10个品种核桃青皮、仁、分心木中主要营养成分总体优于普通核桃。

Comprehensive evaluation and analysis on quality of walnut in different main producing areas in China

In order to explore the quality difference of walnut in different main producing areas in China, ten representative samples of walnuts in Yunnan and twelve samples of common walnuts in other producing areas were selected to analyze and evaluate the main nutritional components of green skin, kernel and distraction wood of walnut. The contents of flavone, tannin and juglone in walnut green skin, the contents of crude protein, crude fat, amino acid, vitamin E, melatonin and phospholipid in walnut kernel, and the contents of crude fat, crude protein, flavone and amino acid in distraction wood were determined. The principal component analysis of walnut quality in different main producing areas was carried out. The results showed that the main components in green skin, kernel and distraction wood of ten main walnut varieties planted in Yunnan were superior to those of common walnut in general.
