| 摘 要： | 作者以中性洗涤剂法(AACC法)试验证明:样品的粗细度以40目为宜,样品在热中性洗涤液中浸煮1小时,测定结果符合要求;用十氢化萘作为去泡剂优于正辛醇;采用两种方式测定回收率,结果为94.1至100.4％,8个小麦样品平行试验的变异系数为1.8％。本法所用设备简单、容易操作、准确度和精密度较高,适合谷物和谷物食品样品的测定。

| Abstract: | The Neutral detergent method (AACC method) for determining insoluble dietary fiber in cereals and cereal foods has been used in this experiment. The results showed that the suitable size of the sample was 40-mesh and the better period for digestion in hot neutral detergent solution was one hour for determination. Decahydronaphthalene as a defoaming agent was better than n-octane. The average recoveries of two different ways were from 94.1% to 100.4%. The coefficient of variation for eight wheat samples was 1.8%. Because of its simple equipment, easy operation and good accuracy, this method would be suitable for determination of cereals and cereal foods. |
