Abstract
A method of extracting a polypeptide from avian eggshell membranes. The method includes fermenting the avian eggshell membranes in a fermentation process, harvesting a fermented product, and processing the fermented product to extract the polypeptide. Prior to fermentation, the eggshell membranes are separated. Optionally, the eggshell membranes are dried. The processing of the fermented product can extract collagen, amino acids, or other high value polypeptides. Separating the eggshell membranes from eggshells may be performed using an acidic solution to assist in eliminating contaminants.
