Abstract
A stable dispersion of insoluble collagen is provided by a microfluidization process. The dispersions of insoluble collagen protein remain in stable suspension under long term storage conditions, with minimal or no settling or precipitation. More specifically the invention provides a stable dispersion of insoluble collagen comprising collagen particles wherein 50% by volume of said particles are less than 30 micrometers in width. These dispersions provide collagen in an aqueous form, which enables ease of incorporation into food and beverages and ease of administration to people or other mammals in need of collagen.

A stable dispersion of insoluble collagen comprising collagen particles wherein 50% by volume of said particles are smaller than 30 micrometers in width.
A method of producing a stable dispersion of insoluble collagen comprising the steps of
- mixing dried powdered cartilage material with water;
- processing the formulations in a microfluidizer processor;
- and
- cooling the material immediately after it passed through the microfluidizer processor.
The method of 12 wherein the microfluidizer unit is an M-110S Microfluidizer® processor (Microfluidics Corp., Newton Mass.) using a G10Z (87 μm) interaction chamber or a H30Z (200 μm) interaction chamber at a pressure from 10,000 to 25,000 psi from one to five passes.
The method of 13 wherein the pressure is 23,000 psi and five passes are used.
