Title: Edward J Diefendorf: Innovator in Enzymatic Processing
Introduction
Edward J Diefendorf is a notable inventor based in Audubon, NJ (US). He has made significant contributions to the field of enzymatic processing, particularly in the treatment of materials containing chromium and protein. With a total of 2 patents, Diefendorf's work addresses critical environmental challenges in the leather tanning industry.
Latest Patents
Diefendorf's latest patents focus on the enzymatic processing of chromium-containing protein materials. The first patent describes a method where chromium-containing protein materials are treated by combining them with water and an alkali additive. This mixture is held at a temperature between 60°C and 85°C for a specified duration. The process results in the solubilization of gelable protein, which can then be filtered to remove the aqueous phase. The remaining chrome-containing proteinaceous cake undergoes hydrolysis using enzymes, producing a product that can be utilized in feeds, fertilizers, and cosmetics.
The second patent outlines a similar process, emphasizing the treatment of materials containing both chromium and protein. This method involves combining the material with water and an additive that provides an alkaline pH along with calcium or magnesium as an enzyme cofactor. The mixture is maintained at a temperature of 60°C to 75°C for a set period, followed by hydrolysis to yield solubilized hydrolyzed protein and insoluble chromium. This innovative approach also aims to recycle chrome into the tanning process while producing useful protein hydrolyzates.
