Not only does whey have excellent processing properties, it is also a far more versatile component in our diets than most people might think.
The wide range of positive qualities and effects of whey - appreciated even back in ancient times - are what makes whey and whey products so nutritionally valuable. A fact which extensive research has repeatedly proved.
Because of their amino-acid composition, whey proteins, a key constituent in whey, are among the most valuable of dietary proteins. The high concentration of essential amino acids they contain mean these proteins are an ideal addition to others, especially vegetable proteins, which they enhance considerably. Table 2 provides a comparison with other dietary proteins. This comparison uses sweet whey, the type of whey most frequently used in food production, and illustrates just how valuable whey is in terms of its nutritional value. Sweet whey is rich in vitamins, most notably B-group vitamins, the most prominent of which are B2, B12, B1 and B6.
