Effect of skim milk-alginate beads on survival rate of bifidobacteria

Encapsulation of Lactobacillus bulgaricus in carrageenan-locust bean gum coated milk microspheres with double layer structure

“…Indeed, effectiveness in protecting probiotic bacteria using chitosan-coated alginate microspheres was reported by Koo, Cho, Huh, Baek, & Park (2001). Yu, Yim, Lee, & Heo (2001) also reported that bifidobaceria and Lactobacillus casei encapsulated in alginate-chitosan beads had higher viability than in alginate without chitosan. The chitosan coating could provide protection for encapsulated probiotics in bile salt solution due to an ion exchange reaction between the beads and bile salt (Murata, Toniwa, Miyamoto, & Kawashima, 1999).…”

The influence of coating materials on some properties of alginate beads and survivability of microencapsulated probiotic bacteria

“…This will protect encapsulated cells from interacting with the bile salt. Yu, Yim, Lee, and Heo (2001) and Koo et al (2001) also reported that bifidobacteria and L. casei entrapped in alginate beads containing chitosan had higher viability than in alginate without chitosan.…”

“…Many scientists have also reported that survival of microencapsulated B. longum (Woo, Lee, & Heo, 1999;Lee & Heo, 2000;Lee et al, 2001a), and B. breve (Lee et al, 2001b) was higher than that of the free cells. Moreover, Yu et al (2001) found that the survival rate of bifidobacteria in alginate beads containing chitosan was higher than that of alginate beads.…”

Survival of probiotics encapsulated in chitosan-coated alginate beads in yoghurt from UHT- and conventionally treated milk during storage

“…The coating of alginate beads with polycations has been extensively studied in pharmaceutics and biotechnology (Alexakis et al, 1995;Luca et al, 2001;Fiszman, Karara, Finocchiaro, & Glikin, 2002). Its effectiveness has also been investigated for encapsulated probiotics such as Lactobacillus casei, Bifidobacterium longum, B. infantis and B. breve in digestive juices (Koo, Cho, Huh, Baek, & Park, 2001;Yu, Yim, Lee, & Heo, 2001) and has been found to improve their survival.…”
