Abstract

The present invention relates to plant based materials, methods for their manufacture and biomaterials incorporating plant based materials.

First claim

The invention claimed is:

1 . A thermoreversible process to obtain plant-based hydrogels comprising:
a) forming a solution comprising one or more plant-based protein(s) in a solvent system, wherein the one or more plant-based protein(s) are selected from the group consisting of soybean, pea, rice, potato, wheat, or sorghum, and the solvent system comprises miscible co-solvents; wherein a first co-solvent increases solubility of the plant-based protein(s), and a second co-solvent decreases solubility of the plant based protein(s); and b) inducing the protein in the solution to undergo a sol-gel transition to form a plant-based protein hydrogel.

2 . The method according to claim 1 , further comprising:
c) forming the plant-based protein hydrogel into a structured material selected from the group consisting of a film, a thin film, a micropatterned film, a micropatterned thin film, a microstructured thin film, a nanostructured thin film, a microgel, a microcapsule, a microbead, a bioscaffold, a bio-support, a sponge, a microscale-sponge, a hard capsule, or a functional coating.

3 . The method according to claim 1 , wherein the first co-solvent is an organic acid selected from the group consisting of acetic acid, glycolic acid, lactic acid, malic acid, citric acid and/or tartaric acid; and/or wherein a second or further co-solvent(s) is an aqueous buffer selected from the group consisting of water, ethanol, methanol, acetone, acetonitrile, dimethylsulfoxide, dimethylformamide, formamide, 2-propanol, 1-butanol, 1-propanol, hexanol, t-butanol, ethyl acetate or hexafluoroisopropanol.

4 . The method according to claim 1 , wherein solvent system comprises a ratio of the first co-solvent to the second co-solvent of about 20-80% v/v.

5 . The method according to claim 1 , further comprising mechanical shear of said protein solution comprising one or more plant-based protein(s) and a solvent system.

6 . The method of claim 1 , wherein the solvent system is thereafter removed such that the plant-based protein hydrogel no longer has thermoreversible properties.

7 . The method of claim 1 , wherein the solution is heated to a first temperature above the sol-gel temperature of the one or more plant-based protein(s), then reduced to a second temperature below the sol-gel temperature of the one or more plant-based protein(s).
