The results showed that the irradiation treatment in the dose of 2.0-8.0kGy is not significantly effective to the contents of total sugar, crude protein and crude fat in walnut powder. The content of crude fiber in irradiated walnut powder increased, but not significantly. The irradiation had barely change on the contents of the lauric acid and myristic acid, and non-significant effects on the contents of palmitic acid, palmitoleic acid, stearic acid, leinoleic acid, arachidic acid and linolenic Acid. However, the irradiation contributed to significant increase in the content of oleic acid with the irradiation dose. When irradiation dose reached 8.0kGy, the content of oleic acid had an increase of 4.3%. Irradiation will not change the sensory index of walnut powder much when irradiation dose is lower than 8.0kGy.

结果表明：剂量为2.0～8.0kGy时，辐照对核桃粉中的总糖、粗蛋白和粗脂肪含量无显著影响；辐照后的粗纤维含量有一定的增加，但不显著；辐照对核桃粉中的月桂酸和肉豆蔻酸含量基本没有影响，对棕榈酸、棕榈油酸、硬脂酸、亚油酸、花生酸和亚麻酸含量有一定的影响，但不显著；辐照后核桃粉中的油酸含量随辐照剂量的上升而显著增加，剂量达到8.0kGy时，油酸含量增加了4.3%。8.0kGy以下辐照对核桃粉色泽、气味、口感无明显改变。
