Abstract
A method of manufacture of crosslinked, edible, porous hollow fibers and sheet membranes suitable for the manufacture of clean meat products, the hollow fibers and sheet membranes made therefrom and methods of use thereof.
Claims39
A method for manufacturing cross-linked, edible, porous hollow fibers or sheet membranes, comprising:
- a) providing:
- i) one or more edible proteins, ii) one or more solvents iii) a formation bath;
- wherein the one or more solvents or the formation bath also comprise one or more multivalent cations or anions or a buffer solution;
- b) co-mixing the one or more edible proteins in the one or more solvents to form a mixture;
- c) extruding the mixture into the formation bath to form an extruded hollow fiber or casting the mixture into the formation bath to form a sheet membrane;
- and
- d) exposing the extruded hollow fiber or sheet membrane to an energy source selected from one or more of heat and irradiation sufficient to at least partially crosslink the one or more proteins to form cross-linked, edible, porous hollow fibers or sheet membrane.

A method for manufacturing cross-linked, edible, porous hollow fibers or sheet membranes, comprising:
- a) providing:
- i) one or more edible proteins, ii) one or more edible polysaccharides, iii) one or more solvents and iv) a formation bath, wherein the formation bath comprises one or more of calcium, zinc, magnesium, iron and potassium, in combination with one or more of 1) water, acetic acid, citric acid, lactic acid, phosphoric acid, malic acid, tartaric acid, or one or more of 2) sodium hydroxide and potassium hydroxide;
- b) co-mixing the one or more edible proteins and one or more edible polysaccharides in the one or more solvents to form a mixture;
- c) extruding the mixture into the formation bath to form an extruded hollow fibers or casting the mixture to form a sheet membrane;
- and
- d) exposing the extruded hollow fiber or sheet membrane to an energy source selected from one or more of heat and irradiation sufficient to at least partially crosslink the one or more proteins to form cross-linked, edible, porous hollow fibers.
