Testing reports values for total protein. Organic matter is destroyed by boiling in conc. sulfuric acid. Then the digestion mixture is alkalized with sodium hydroxide to free up the ammonia prior to distillation. The ammonia is steam distilled into boric acid solution. The content of nitrogen and protein is then determined by titration of the borate complex.
High fat content may interfere with analysis.
