Size-based fractionation of natural milk fat globules was investigate. A two-stage centrifugal separation method was employed in all studies. Depending upon the level and combination of the independent variables, D[4,3] of the fractionated cream ranged from 1.32 to 5.2 mu m. Fat yield in the cream with smallest (1.32 mu m) and largest (5.2 mu m) average fat globule size was 9% (w/w) and 39% (w/w), respectively. The fat content of the cream with the smallest and largest average fat globule size was 33.6% (w/w) and 32.75% (w/w), respectively. The Zeta potential of all milk fractions and creams ranged from 12.4 to 16.45 mV. An increase in feed rate and a decrease in rotational speed reduced the fractionating performance of the modified cream separator. The smaller upper separating cone helped concentrate the bigger fat globules in the cream. (C) 2021 Elsevier Ltd. All rights reserved.
