Lactose is the naturally occurring carbohydrate (as sugar) found in milk. To help digest lactose your body contains the enzyme lactase however some people have difficulty digesting the enzyme which makes low-lactose or lactose-free products a potential option. The most common way to reduce lactose enzyme in products is to add lactase enzyme (similar name, but different) which naturally converts the lactose into more easily digestible carbohydrates (glucose and galactose). According to Australian food regulations, food/beverages that claim to be low lactose must contain no more than 2g per 100g, and for a food/beverage to claim it is lactose-free it contain no traceable amount of lactose.
Here at Rokeby Farms, our approach to reducing lactose is slightly different – our unique cold filtration process (which we use to increase the natural protein level in the milk) starts by completely removing (not converting) some of the naturally occurring lactose from the milk. We then add lactase enzyme to help convert some of the remaining lactose left in the milk. Our Rokeby Farms smoothies are not lactose-free but are low-lactose and may be able to be enjoyed by people who are sensitive to lactose.
