FAQ

Frequently asked questions.

Where does lactose come from?▾
Lactose is the primary carbohydrate found in the milk of mammals, including cows, goats, and humans. It's naturally synthesized in the mammary glands and serves as a significant energy source for young offspring.
What role does lactose play in dairy products?▾
Beyond sweetness, lactose contributes to the browning of baked goods containing milk and can improve the texture of dairy products, adding a smooth mouthfeel. It also plays a role in fermentation processes, like in yogurt and cheese making, where bacteria convert it into lactic acid.
What does 'lactose intolerant' mean?▾
Lactose intolerance is a common digestive condition where the body cannot fully digest lactose, due to a deficiency of the enzyme lactase. This leads to symptoms like bloating, gas, and discomfort after consuming dairy products containing lactose.
