Determination of crude protein
WebCRUDE PROTEIN 1: Scope and Field of Application This method is for the determination of crude protein in feeding stuffs by the Kjeldahl method for nitrogen. 2: Principle The sample is digested by sulphuric acid in the presence of a catalyst. The acidic solution is made alkaline by a sodium hydroxide solution. The ammonia released is distilled and WebCrude protein content is calculated from the N content of the feed, using Kjeldahl method. Crude P can be estimated in 2 methods: Macro Kjeldahl: For feed containing large …
