摘要：The modified Henneberg-Stohmann method for determination of crude fibers was simplified as follows. The use of linen, copper net, sintered glass filter, and electric oven was eliminated. Filtration was made only once. In this simplified method, crude fibers are boiled with 1.25% sulfuric acid, 6.43g of solid sodium hydroxide is added in small portions to the boiled solution to bring the concentration of sodium hydroxide to 1.25%, and the solution is boiled for 30 minutes. The boiled solution is filtered through a Gooch crucible, and residue on the crucible is ignited on a direct flame until the dark colour becomes white. Removal of fat with ether is usually not necessary. The time of experiment is markedly shortened and the resultant values were almost the same as that by the usual method.
