摘要: Abstract Since there has been a lack of knowledge concerning the molecular understanding specific fouling mechanism during deposit layer structure formation, in this study membrane filtration single whey protein fractions was investigated at various pH and ionic strength. During both individual proteins mixtures, found to be strongly correlated repulsive inter-particle forces pH-dependent cross-linking reactions. A disproportionate decrease resistance from 6.4 7.5 observed when with free thiol group were present. At 3, α-lactalbumin exists apo-form, which may cause an increased acidic pH. Based on insights gained study, mixtures comprising different native either acid or rennet can explained.
