“…These results concur with numerous researchers that have also shown that increasing lactose concentrations increase GOS yields (Iwasaki and others 1994; Van Laere and others 2000; Albayrak and Yang 2002a, 2002b). A total of 270 g/L or 27% (w/v) lactose was used as an upper limit, since higher concentrations would be too viscous for membrane filtration (Scott 1996). Our results also indicated that extending incubation time does not necessarily increase GOS amount.…”

“…Depending on membrane‐pore size, enzyme is retained while smaller chemicals (that is, sugars, GOS) are permeated. Under these conditions, shearing and resultant inactivation may increase with increasing fluid pressure (Bowen and Quan 1992; Scott 1996). To date, there have been no studies that have investigated the effect of fluid pressure on β‐galactosidase.…”

“…As well as the formation of a gel layer, another phenomenon, ''membrane fouling,'' often occurs. Fouling gives rise to a steadily declining flux with time and can be attributed to a variety of mechanisms including changes in the chemical nature of the gel layer as crosslinking and compaction (Scott, 1996).…”

“…Αυτές οι αλληλεπιδράσεις αθροιστικά μπορεί να είναι απωστικές ή ελκτικές και να οδηγήσουν στη μεγαλύτερη ή μικρότερη συγκράτηση και δέσμευση της διαλυμένης ουσίας στην επιφάνεια της μεμβράνης. Το γεγονός αυτό, ακολούθως, μπορεί να προκαλέσει μείωση στην διαπερατότητα [36,38]. Η επίδραση της οσμωτικής πίεσης στις UF μεμβράνες είναι μικρή και η εφαρμοζόμενη στην πλευρά τροφοδοσίας πίεση, συνήθως 1-7 bar, ασκείται πρωταρχικά για να ξεπεραστεί η ιξώδης αντίσταση κατά την διέλευση του ρευστού από το δίκτυο πόρων της μεμβράνης [38].…”
