Summary The effect of hydrostatic pressure on the physicochemical properties of milk fat globules and the milk fat globule membrane (MFGM) was studied. The median diameter (2.6 μm) and size distribution (1 to 10 μm) of the milk fat globules were not affected by pressurization at 100–400 MPa, but were respectively increased to 4.1 μm and 1 to 18 μm at 800 MPa. Lipoprotein lipase could not attack milk fat globules pressurized even up to 800 MPa, indicating that hydrostatic pressure did not cause damage to the membrane enveloping the milk fat globule. About 25% protein and phosphorus in the pressurized isolated MFGM was precipitated by centrifugation at 3000 x g, indicating that MFGM was aggregated. The membrane enveloping milk fat globules ruptured once by sonication was repaired by pressurization. |
