Microfiltered Whey

Microfiltered whey is a protein-rich byproduct of cheesemaking. It is produced by filtering milk to separate the liquid whey from the solid curds. The microfiltration process further refines the whey, concentrating its protein content while removing most of the fat and lactose.

Manufacturers add microfiltered whey to foods primarily as a protein source and for its emulsifying properties. It helps improve texture and stability in products like protein powders, nutritional supplements, and some baked goods. It is often found in meal replacement supplements and protein bars.

Microfiltered whey is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of high-quality protein, which is essential for muscle repair and growth. International bodies like JECFA have evaluated whey proteins, and they are widely consumed without significant health concerns at typical intake levels. While generally safe, individuals with lactose intolerance may need to consume products with lower lactose content.
