Removal of bacteria, spores and somatic cells from milk by centrifugation and microfiltration techniques

Gesan-Guiziou, Geneviève
Bactofugation (or centrifugation) and microfiltration are commercial and effective techniques for the physical removal of bacteria, spores and somatic cells from milk. Centrifugation is applied to separate components (microorganisms, fat globules, insoluble proteins, etc.) that have different densities compared to the dispersing phase, and microfiltration is mainly based on particle size exclusion using a semi-permeable membrane. This chapter gives a description of these two technologies (principle and operating conditions). It presents the performances of both techniques in particular with respect to the removal of bacteria, spores and somatic cells. Finally it discusses their possibilities and limitations in the dairy industry.
