- 摘要:
- 以青海省不同核桃分布区的地方核桃坚果为试材,分别采用凯氏定氮法、索氏抽提法和气相色谱法测定了112份核桃仁蛋白质含量、粗脂肪含量和主要脂肪酸组成成分及含量,分析了不同地区核桃内含物的多样性和含量变异程度。结果表明:地方核桃的蛋白质平均含量为15.97%,粗脂肪平均含量为64.26%,主要脂肪酸及平均含量依次为亚油酸55.49%、油酸24.70%、亚麻酸11.66%、棕榈酸6.05%、硬脂酸1.98%,其中不饱和脂肪酸含量达91.85%;除此之外,地方核桃脂肪酸组成成分相同,但含量有显著差异。
- Abstract:
- Taking 112 walnut local varieties kernel from different eco-geographical regions as research materials,protein content,crude fat content and main fatty acid content and composition were determined by the method of Kieldahl,Soxhlet extraction and gas chromatography respectively,substance diversity and content variation of walnut in different region were analyzed.The results showed that the average content of protein were 15.97%,crude fat were 64.26%,the average content of main fatty acid were linoleic 55.49%,oleic 24.70%,linolenic 11.66%,palmitic 6.05%,stearic 1.98% respectively.The unsaturated fatty acid content reached to 91.85%,the correlation analysis showed significant differences (P<0.05)in the fatty acid content.
