摘要
将面粉试样与12%的盐酸溶液共沸,使样品中的戊聚糖水解,生成戊糖,戊糖脱水生成糠醛,再蒸馏出糠醛,并用四溴化法测定蒸馏出的糠醛含量,据此换算得出戊聚糖含量。
The method utilized the hydrolysis of the pentosans to furfural by 1 2%boiling hydrochloric acid,then the furfural is distilled at a controlled rate .Through determinating the content of distilled furfural,the content of pentosan s can be calculated by a formula.The result is also reasonable.
