Specified Risk Materials (SRMs) are the areas of cattle in which the infecting agent that causes Bovine Spongiform Encephalopathy or mad cow disease most likely concentrate. In Canada several thousand tonnes of SRMs are landfilled at considerable economic and environmental costs. This project aims to demonstrate a technology platform for the conversion of SRMs into industrial foaming agents. SRMs were hydrolyzed at 180oC – 260oC followed by the extraction of the peptide component. Subsequently, the peptides were characterized using Fourier Transform Infrared Spectroscopy and Size Exclusion Chromatography, and the foaming performance (foam stability and surface tension) at pH 7.0 was evaluated. The peptides recovered at 180oC and 220oC performed similarly to an industrial foaming agent (BIOSOFT N25-9).
