Whey powder. It is made by drying whey, which is a by-product of cheese or casein. Normal whey powder is white to light yellow in color and has milk flavor. If it is bleached during processing, its products will appear milky white, and if it is not bleached, it will appear white to light yellow, which is due to the different colors of whey produced by producing different cheeses.
