摘要
以河北山区常见坚果——核桃、山核桃、松子、板栗和杏仁5种坚果为原料,对其粗脂肪、蛋白质、总糖、膳食纤维、脂肪酸、总酚和黄酮等主要营养及活性成分进行分析。结果显示,5种坚果均含有丰富的多种营养素和活性成分,不同品种间含量差异显著。主要营养成分:粗脂肪53%~70%(板栗仅4.71%除外),蛋白质10%~24%,总糖9%~11%(板栗达72.97%除外),膳食纤维5%~13%。主要活性成分:多不饱和脂肪酸21%~79%,总酚和黄酮含量分别在0.3%~3.6%和0.2%~0.9%之间。
Walnut,pecan,pine nut,chestnut and almond collected from Hebei mountain area were tested.Their main nutrient and active components such as crude fat,protein,total sugar,dietary fiber,fatty acid,total phenol and flavonoid were measured and compared.The results showed that these nuts are nutrient-dense foods with complex matrices rich in polyunsaturated fatty acid and other active components,while significant differences have been found in the contents of different nut varieties.The contents of crude fat,protein,total sugar and dietary fiber were respectively as follows:53%-70%(except chestnut,4.71%),10%-24%,9%-11%(except Chestnut,72.97%)and 5%-13%.The total polyunsaturated fatty acid content changed from 21%to 79%in nuts oil.The contents of total phenol and flavonoid were 0.3%-3.6%and 0.2%-0.9%,respectively.
