Why does lactose-free milk taste sweeter than regular milk?

Milk is a rich source of proteins, minerals and vitamins. However, an increasing number of people have digestive problems when drinking milk. In most cases, there occur the symptoms of lactose intolerance, which prevents the digestion of lactose (milk sugar). For that reason, lactose-free milk is recommended even for people with digestive problems, who can consume it freely.

Lactose-free milk differs from regular milk since it contains already decomposed lactose. It is the process in the production enabled by the enzyme lactase. The enzyme lactase, which people with lactose intolerance lack, decomposes lactose to glucose and galactose – forms of sugar, which the body can digest. Glucose and galactose have a higher index of sweetness than lactose itself. That is why lactose-free milk tastes sweeter than regular milk despite the exact same sugar content.
