Abstract

The crude fiber method in use today was originated in Germany by Henneberg and Stohmann (1) about 85 years ago and is known as the Weende method after the name of their experiment station. Their method consists of boiling a dried and ether extracted sample (about 1 gram) for 30 minutes in 200 ml. of a 1.25o/o sodium hydroxide solution. The residue is filtered off and washed free of alkali with hot water in a Gooch crucible prepared with a treated asbestos mat, dried in a 100 degree C oven, weighed, ashed and reweighed. The loss in weight upon ashing is calculated as the percentage of crude fiber of the material sampled. This method is the present official method of the Association of Official Agricultural Chemists.
