testing for protein

Submitted by iwaldron on Tue, 08/07/2012 - 4:38am.

We are not sure why you are having trouble getting beans and yogurt to test positive for protein, but one possibility is that Biuret solution may become less sensitive over time, so we recommend using fresh Biuret solution. Gelatin tests positive for protein because it is a mixture of proteins and peptides derived from collagen, a protein that is abundant in bones, connective tissue and skin.
