What is the lactose percentage in cow's milk?

4.4%
4.8%
5.1%
4.9%

The correct answer is: 4.8%

Cow's milk typically contains about 4.7% to 5% lactose, with the most commonly cited average being around 4.8%. Lactose, which is the sugar found in milk, is a disaccharide consisting of glucose and galactose, and its percentage can vary slightly based on factors such as breed of cow, diet, and the stage of lactation. This range is consistent across most studies and analyses of cow's milk composition, making the answer of 4.8% the most accurate representation of lactose content in cow's milk. Understanding this percentage is important for those in the cheese industry since lactose plays a significant role in cheese production and influences fermentation processes.
