Abstract
The invention provides a new collagen based technology. The invention provides a dry collagen powder as a precursor for the preparation of an homogeneous thermoplastic collagen-based composition, which may further comprise additives. The present invention relates also the use of said composition in the manufacturing of solid articles conformed according to plastic technology, and to the articles.
Claims27
A homogeneous thermoplastic collagen-based composition consisting of:
- 40 wt % to 65 wt % of non-crosslinked dry collagen powder particles and being based on a fibril forming collagen wherein said collagen has been denatured to a degree of at least 90%, having an average molecular weight of at least 500 kD, a solubility equal to or greater than 25% in water at 60° C. and a particle size in the range of about 30 μm to about 350 μm;
- 10 wt % to 20 wt % of glycerin;
- and an additive selected from the group consisting of proteins, biodegradable polymers, blowing agents, modifiers, fillers, lubricants, preservatives, colorants, flowability improvers, flavouring agents and scents, nutritional agents and mixtures thereof;
- and 20 wt % to 40 wt % of water;
- wherein said non-crosslinked dry collagen powder and said water from the homogeneous thermoplastic collagen-based composition.
