Abstract:
1. A process for recovering protein and lipid from animal byproducts or krill comprising: a. homogenizing animal byproducts or krill with water to form a homogenate; b. solubilizing the homogenate by adjusting the pH of the homogenate to form a first pH adjusted composition; wherein, antifoam agents are added to the first pH adjusted composition; c. separating the first pH adjusted composition forming a light fraction containing lipids, a medium fraction containing protein in solution, and a heavy fraction containing fat-free impurities; d. adjusting the pH of the medium fraction to about the isoelectric point of the proteins thereby precipitating the medium fraction forming a second pH adjusted composition; wherein, antifoam agents are added to the second pH adjusted composition wherein the proteins have been precipitated; and e. separating the second pH adjusted composition forming a light fraction containing water and a heavy fraction containing precipitated proteins; wherein the byproducts include skin, bone, scales, fin, heads, frames, or viscera.
