摘　　要：修改采用AACC32-20(1999)《不溶性膳食纤维测定方法》,对原国家标准GB/T9822-1988《谷物不溶性膳食纤维测定方法》进行了研究和讨论分析。结果表明,纤维测定仪器可以作为谷物不溶性膳食纤维的测定仪器,样品的粉碎粒度为20-30目,α-淀粉酶浓度为2.5%(W/V),取消了试剂中的十氢萘,样品不溶性膳食纤维测定值的相对误差小于10%。AACC Method 32--20 （1999）Insoluble Dietary Fiber was revised, and GB/T Method 9822--1988 Insoluble Dietary Fiber was discussed. The results showed that the particle size of the can be used as the equipment of deter- minaion of insoluble dietary fiber in cereals, the particle size of the sample ground was 20--30 mesh, s--amylase concentration was 2.5% （w/v）, and decahydronaphthalene was canceld. The relative error of the determined value of insoluble dietary fiber in sample was less than 10%
