Description : 
Lactose is a sugar that is found most notably in milk. Lactose makes up around 2~8% of milk (by weight), although the amount varies among species and individuals. It is extracted from sweet or sour whey. It has been estimated that the annual worldwide availability of lactose as a by-product of the dairy industry is several million tons. Whey contains about 4.8% of lactose, which may be purified by crystallisation.As it gives free radicals by mechanochemistry, it is possible to use lactose to follow by ESR (electron spin resonance) the energy used during a milling process.Lactose is hydrolysed to glucose and galactose, isomerised in alkaline solution to lactulose, and catalyticaly hydrogenated to the corresponding polyhydric alcohol, lactitol
