Researchers in Singapore are developing a sustainable meat substitute from button-based proteins extracted from mushrooms, a type of food waste. This new product, which is expected to be commercialized, is richer in protein, iron, and amino acids than typical plant-based meat alternatives. The team at Singapore's NTU Food Science and Technology Program believes this product is a healthier and more nutritious option, as it is closer in taste and texture to meat than current plant-based meat substitutes. Additionally, the production of this mushroom-based protein will help reduce food waste instead of contributing to environmental pollution.
