Microencapsulation of a probiotic and prebiotic in alginate-chitosan capsules improves survival in simulated gastro-intestinal conditions

Microencapsulation of probiotics using sodium alginate

“…The association of these compounds with calcium alginate leads to the formation of more stable capsule, allowing the formation of a double wall in the microcapsule (CHÁVARRI et al, 2010). LEE et al (2004) investigated the effect of microparticles of alginate coated with three types of chitosans of different molecular weight on the survival of Lactobacillus bulgaricus KFRI 673 in simulated gastric juices, intestinal juices and their stability during the storage at 4 and 22ºC.…”

Soy Protein Isolate-Alginate Microspheres for Encapsulation ofEnterococcus faecalis HZNU P2

“…However, the viability of free E. faecalis HZNU P2 decreased from around 11 Log CFU/mL to 9.85 and 9.45 Log CFU/mL for 2.0 h exposure at SGF pH 2.5 and 2.0, respectively. Many studies have indicated that encapsulation can help in improving the survival of the cells in SGF (Chandramouli et al 2004;Krasaekoopt et al 2004;Iyer and Kailasapathy 2005;Annan et al 2008;Chavarri et al 2010;Pan et al 2013;Shi et al 2013a, b;Chen et al 2014;Sathyabama et al 2014). To date, the use of plant protein isolate as a wall material for probiotic encapsulation, particularly soy protein isolate, is extremely limited.…”

Encapsulation Technology to Protect Probiotic Bacteria

“…In fact, Ross and collaborators [66] reported that neither inulin nor polydextrose enhanced probiotic viability of spray-dried probiotics. In another study, it was also observed that when quercetin was added together with probiotics, the microencapsulation yields and survival rates were lower than for the microorganism without quercetin [67]. A lot of other studies have employed of spray-drying technology to encapsulate probiotic cells, as noted in the table 1.…”
