对贵州、河北、重庆等8个地区的核桃在理化性质、油脂中金属元素和脂肪酸组成等方面进行对比研究.采取冷榨法获得核桃油样,对8种核桃的理化指标,核桃油中金属元素、维生素E和脂肪酸组成进行测定.结果表明:贵州核桃的粗蛋白质含量及核桃油的油酸、维生素E和金属元素含量均较高,其中贵州核桃油中铜、钙、镁和钾的含量居8种核桃之首,核桃油中维生素E含量为662.24 μg /kg,居8种核桃的第3位.贵州核桃具有更好的氧化稳定性及营养价值.

The physicochemical properties of walnut, metal elements and fatty acid composition of walnut oils from eight regions of Guizhou, Hebei, Chongqing, etc. were compared and studied. The walnut oil samples were obtained by cold pressing method. The physicochemical indexes of eight kinds of walnut, metal elements, vitamin E and fatty acid compositions of walnut oils were determined. The results showed that the crude protein content in walnut, and contents of oleic acid, vitamin E and metal elements in wal- nut oil from Guizhou were higher. The cont...
