METHOD FOR THE SEPARATION OF THE LACTOSE FROM MILK FOR THE PRODUCTION OF LACTOSE-FREE MILK, AND USE OF THE BY-PRODUCT
The invention relates to a method for separating lactose from milk in order to produce lactose-free milk, and the use of the by-product, comprising a standardisation of the milk to be treated, the application of an ultra-filtration step with which a permeate is obtained that will be treated with nano-filtration in order to produce a retentate of nano-filtration. Between the ultra-filtration and the nano-filtration there is a diafiltration step.
