This study investigated how consumers respond to patties made by combining mushrooms with egg white. Researchers tested 16 different versions of these patties, varying the amount of mushroom (0-30%), the type of mushroom (white or crimini), and cooking method (steamed or roasted). Results showed that patties with up to 20% mushroom were well-accepted by consumers, with steamed patties made from crimini mushrooms being most popular. The flavor combination of mushrooms and egg white was rated positively by almost all participants.
