“…Microencapsulation is a physicochemical or mechanical process in which the bacterial cells are entrapped within coatings of hydrocolloidal materials, providing protection from adverse conditions such as high acidity and low pH, bile salts, cold shock (induced by process conditions such as deep freezing and freeze drying), molecular oxygen (in the case of obligatory anaerobic microorganisms), heat shock (caused by the process conditions such as spray drying), and chemical antimicrobial agents applied in order to inhibit or reduce cell injuries/loss and increase viability (Korbekandi et al, 2008;Adhikari et al, 2000;Krasaekoopt et al, 2006;Sultana et al, 2000;Mortazavian et al, 2008;Krasaekoopt et al, 2004;Hansen et al, 2002;Lee and Heo, 2000;Rao et al, 1989;Wenrong and Griffiths, 2000;Champagne 2012;Heidebach et al, 2012). Other advantages including increase in sensory stability and/or its improvement and immobilization of the cells for their homogeneous distribution throughout the product, can also be achieved (Mortazavian et al, 2007b).…”
