Researchers developed a method to turn soybean whey (a waste product from tofu and soybean protein production) into delicious plant-based yogurt. By removing salt through electrodialysis and concentrating the whey, then fermenting it with yogurt bacteria, they eliminated the unpleasant beany flavors and harmful compounds that make raw soybean products unappetizing. The resulting yogurt has a creamy texture, pleasant flavor, and better nutrition compared to untreated soybean whey, offering an environmentally friendly way to use agricultural byproducts.
