Abstract
A method for producing a collagenous material in particle form, includes: extracting a collagen- and fat-containing animal raw material using an aqueous extraction solution; optionally separating at least one part of the aqueous phase from the extraction residue; separating the extraction residue into a collagenous solid phase, an aqueous phase, and a fat phase; mixing at least one part of the collagenous solid phase with at least one part of the aqueous phase; at least partly drying the mixed phases; and comminuting the dried phases in order to obtain the collagenous material in particle form.
Claims9
A method for producing a collagenous material in particle form, comprising:
- extracting a collagen- and fat-containing animal raw material using an acidic aqueous extraction solution having a pH of 3.5 to 5.5, to yield an aqueous phase and an extraction residue;
- separating at least one part of the aqueous phase from the extraction residue;
- repeating the preceding extracting and separating by repeatedly extracting the extraction residue, after separation of the aqueous phase, with an acidic aqueous extraction solution having a pH of 3.5 to 5.5, wherein the extraction is carried out a total of two to eight times;
- separating the extraction residue of a last extraction into a collagenous solid phase, an aqueous phase of the last extraction, and a fat phase;
- mixing at least one part of the collagenous solid phase with at least one part of the aqueous phase of the last extraction in a ratio by weight of 1:99 to 1:1;
- at least partly drying the mixed phases;
- and
- comminuting the dried phases in order to obtain the collagenous material in particle form with an average particle size of 20 to 250 μm.
