Particles of collagen material and process for the preparation

摘要

In order to provide a product that is suitable as fat substitute in foods, which can be produced simply and inexpensively and is deemed safe from the nutritional physiology viewpoint and with which the typical texture of fat-containing foods can be simulated as favorably as possible, particles of collagen material are proposed which are substantially insoluble and swellable in water, wherein in swollen state the particles have an average diameter of less than approximately 150 μm. A process for the production of this product is additionally proposed.

主权项

1. Particles of collagen material comprising ossein, which are substantially insoluble in water, and which are swellable in water to have a diameter in a swollen state that is approximately 5- to 10-fold larger than the diameter of the particles in a dry state, wherein in the swollen state the particles have an average diameter of 20 to 100 μm, and wherein the particles are produced by high-pressure homogenization or wet-grinding of a solid collagen material comprising ossein in a slurry having a pH value of 4.5 to 6.5.
