Method to obtain milk (LFM) with low sugar content starting from milk (M), comprisingat least two steps: a first step in which the milk (M) is subjected to ultrafiltration(UF) so as to produce, at exit, an ultrafiltration permeate (UFP) and an ultrafiltrationretentate (UFR)； and a second step in which the ultrafiltration permeate (UFP)is subjected to nanofiltration (NF) so as to produce, at exit, a nanofiltrationpermeate (NFP) and a nanofiltration concentrate (NFC). The nanofiltrationpermeate (NFP) is continuously recircled directly to ultrafiltration (UF)so as to dilute the ultrafiltration retentate (UFR) and obtain the milk (LFM)from the latter.
