This technology relates to a method for producing plant-based protein, which involves drying and defatting spent coffee grounds, then extracting protein with an alkaline solution, and finally precipitating and recovering it with an acidic solution.
Most spent coffee grounds are discarded, leading to resource waste and environmental problems, such as greenhouse gas emissions.
To address this, this technology extracts plant-based protein from discarded spent coffee grounds using acid precipitation, thereby utilizing it as a raw material for various food and cosmetic products and enhancing sustainability and resource reusability.
