| Abstract | A strain of Lactobacillus brevis, isolated from Thai traditional fermented vegetable was found to be a better probiotic strain than some other commercial strains due to its highest potential in having desired probiotic characteristics which are acid to lerance, bile tolerance and antagonistic effect against pathogenic bacteria. A modified method using calcium alginate for the microencapsulation of this probiotic bacteria introducing the incorporation of different prebiotics (fructooligosaccharide, oligofructose, high amylase corn resistant starch and maltooligosacchride) was used to develop a synbiotic system. Incorporation of high amylase corn resistant starch (a prebiotic) improved an efficiency in encapsulation of viable bacteria. The encapsulated bacteria, however, did not demonstrate a significant increase in survival when subjected to in vitro high acid and bi le salt conditions when compared with encapsulation with calcium alginate but it showed a significant increase in survival when compared with free cells: A preliminary study was carried out in order to monitor the effects of encapsulation with resistant starch on the survival of probiotic L. brevis in yogurt product for a shelf life of 4 weeks at 4°C. This study showed that the survival of encapsulated culture of L. brevis showed a decline in viable count of about 0.9 log over a period of 4 weeks while there was a decline of about 1.6 log in cultures which were incorporated as free cells in yogurt. |
