Minerals in Whey and Whey Fractions

Liquid and dried acid and sweet wheys and the concentrates and permaetes obtained from ultrafiltration of whey were analyzed for major and trace minerals. Calcium, magnesium, sodium, and potassium were determined by atomic absorption and phosphorus by a colorimetric method. Zinc, iron, copper, and m...

Description
Summary:Liquid and dried acid and sweet wheys and the concentrates and permaetes obtained from ultrafiltration of whey were analyzed for major and trace minerals. Calcium, magnesium, sodium, and potassium were determined by atomic absorption and phosphorus by a colorimetric method. Zinc, iron, copper, and manganese were determined by flameless atomic absorption. The composition of all wheys and their fractions differed in nutritionally important minerals. Calcium was three times as great and zinc twenty times as great in acid whey as in sweet whey.
