A » Sweet whey and acid whey are by-products of cheese and yogurt production, respectively. Sweet whey results from the coagulation of milk proteins using rennet, typically in cheese making, and has a higher pH. Acid whey comes from the fermentation of lactose into lactic acid, lowering the pH, often seen in yogurt production. Both types are rich in nutrients but differ in acidity and flavor profiles.

A »Sweet whey is a byproduct of cheese production using rennet, with a pH around 6.0. Acid whey, produced during acid-coagulated cheese or casein production, has a lower pH (around 4.5). The difference affects their applications and nutritional content, making sweet whey more suitable for food products and acid whey often used in animal feed or nutritional supplements.
