The Effect of surfactant on the Isolation of Protein products from chromium- containing solid tannery Waste. Influence on the Process and on the chemical, Physical and functional properties of the resultant Gelatin

摘要

Protein products can be isolated from chrome shavings using two processes that had been demonstrated to be economically attractive. Surfactant is used during the extraction of the Protein products to avoid foam formation. Foam Would make the manipulation of the mixtures Difficult, disturbing the separation of the protein Products from the residual chrome cakes, and Could inactivate the enzyme. The influence of Surfactant on the gelatin isolated from chrome Shavings was studied.
