Abstract
The present disclosure provides extruded or spun, semi-permeable, porous hollow fibres, comprising covalent ester, thioester and/or amide crosslinked polypeptides as well as processes for their production. The hollow fibres may be produced from protein, protein extracts, and/or protein isolates derived from plants, animals, bacteria, algae, archaea, and/or fungi, and in certain embodiments are intended to be suitable for human and/or animal ingestion. In some embodiments, the hollow fibres may be designed to be used in the production of cartridges that are compatible with existing and/or novel bioreactor platforms, for harbouring cell cultures in cultured meat production.
Claims34
A composition comprising a food product comprising a semi-permeable, porous hollow fiber, comprising one or more polycarboxylic acid derived covalent ester, thioester and/or amide bond crosslinked polypeptides wherein:
- (a) the external diameter of the hollow fiber is 500-1200 μm;
- (b) the wall thickness of the hollow fiber is 100-500 μm;
- (c) the lumen diameter of the hollow fiber is 100-500 μm;
- and
- (d) the porosity of the hollow fiber is 10-85%;
- and
- (e) the particle rejection size (PRS) of the hollow fiber is at least 10 μm.
A semi-permeable, porous hollow fiber comprising one or more polycarboxylic acid derived covalent ester, thioester and/or amide bond crosslinked polypeptides wherein said hollow fiber is intended to be edible, and wherein:
- (a) the external diameter of the hollow fiber is 500-1200 μm;
- (b) the wall thickness of the hollow fiber is 100-500 μm;
- (c) the lumen diameter of the hollow fiber is 100-500 μm;
- and
- (d) the porosity of the hollow fiber is 10-85%;
- and
- (e) the particle rejection size (PRS) of the hollow fiber is at least 10 μm.
