Collagenesis Inc. in Beverly, Mass., is one interested party. The fast-growing biochemical firm is researching ways the chicken collagen can be used in health care. The membranes include the unusual Type 10 collagen, which prevents calcification. It could be used to make transplanted heart valves last longer and to treat osteoporosis. MacNeil and Penn State await approval of a patent on the deceivingly simple process to efficiently pull off the stubborn membranes.
Meat processors use a device called a comitrol, a cylinder that looks a little like an oil filter.
On the inside are razor-sharp blades. MacNeil's procedure involves shooting the egg shells through the comitrol, producing a fluffy substance. When that's dumped in water, the shells fall to the bottom and the membrane float to the top. It makes sense. We welcome your feedback.
