Whey Permeate is produced by the removal of protein and other solids from whey. The separation is accomplished by ultrafiltration and/or diafiltration. The product is labeled to reflect protein, ash and lactose content. The acidity of permeates may be adjusted by the addition of safe and suitable pH ingredients. Whey Permeate or Dairy Product Solids are GRAS approved and suitable for both food and feed applications.
