A method of preparing a porous protein scaffold for supporting the growth of biological tissue is described. The method comprises: providing an oil-in water emulsion comprising oil droplets dispersed in a continuous phase comprising a pH-buffered aqueous protein solution, wherein the oil-in-water emulsion comprises a non-ionic surfactant in an amount of 0.01 to 10 volume % of the total volume of the oil phase in the oil-in-water emulsion; gelling the protein around the oil droplets, such as by enzymatic activity or by non-enzymatic activity chemical reaction or by thermally controlled gelation; and removing the oil droplets from the continuous phase. A porous protein scaffold and its uses are also described.
