Abstract: This disclosure provides a protein oleogel comprising plant protein dispersed in a liquid oil phase. The oleogel has a microstructure in the form of fibrils, sheets, or other particles with a high aspect ratio that are substantially not interconnected. It can be manufactured by a process that includes solubilizing and denaturing the protein in an aqueous liquid, flash freezing and drying the protein, and then gradually and gently adding a suitable oil or oil mixture. The protein microstructure releases some but not all of the oil when heated. The oleogel forms a spreadable emulsion in an aqueous liquid that is stable for at least six weeks without evidence of creaming. The oleogel may substitute for oils and fats of animal origin in food, food ingredients, cosmetics, and personal care products. This lessens the impact of food manufacturing on the environment, which helps mitigate climate change.
