谷物、果品蔬菜及植物性饲料中纤维测定方法的探讨

作者以AACC法即不溶性食物纤维法(以下简称新法),用Tecator纤维仪对谷物、果品、蔬菜及植物性饲料等29个样品进行纤维分析并与Heinneberg等人于1860年提出的粗纤维测定方法(以下简称旧法)做了比较,结果表明,在谷物类11个样品中用旧法测定纤维含量仅占新法纤维含量的9.41～34.63％;在秸杆类6个样品中旧法含量只占新法含量的44.46～74.30％,果品蔬菜类中12个样品旧法只占新法的53.62～85.29％。作者认为新法测定谷物及食品的纤维是比较适宜的分析方法。

A STUDY ON THE METHODS OF DETERMINING FIBRE CONTENTS IN GRAIN, FRUITS, VEGETABLES AND FEED STUFFS

Fibre contents of 29 samples of grain, fruits, vegetables and feed were analysed by the AACC method i.e. insoluble dietary fibre method (hereinafter referred to as the new method) with Tecator's fibre analyser and comparison was made with the crude fibre determining method (hereinafter referred to as the old method)advanced by Helnneberg, et al in 1860.The results showed that the fibre contents in 11 samples of grain, 6 of stalks and 12 of fruits and vegetables determined by the old method were only 9.41-34.63, 44.46-74.30 and 53.62-85.29% of that by the new method respectively. So the new method may be appropriate to determine the fibre contents in grain and food.
