- Buttermilk powder offers all the nutrition and flavor of regular buttermilk in a convenient, easy-to-store format. It delivers 8.6 g of protein in a 1-cup serving, as well as lots of potassium, vitamin B-12, calcium, riboflavin and phosphorus, according to the editors of “The Visual Food Lover’s Guide.”
- Unlike regular buttermilk, most powdered buttermilk does not contain live bacteria. According to Amy Thomson of Saco Foods, powdered buttermilk is not meant to be used as a liquid beverage. Buttermilk powder works best in baking, where it adds the acidic tang that heightens the flavors of yeast breads, waffles, pancakes, muffins and quick breads.
