Toned milk is a method, developed in India, of treating buffalo milk by adding skim milk, powdered skim milk and water to buffalo milk. This process decreases the fat content, increases the quantity of available milk, and 'tones up' the non-fat solids level to the original amount. The cost of the milk is reduced, making it more widely available and not a luxury purchase. Buffalo milk has a fat content of about 7-8%, and contains calcium and a non-fat solids content of 9-10%. By reducing the fat content to 3% through the toning process, the available milk quantity is nearly tripled.
