Products containing probiotics have been considered as functional food and the market demand is continuing expend. Abundant researches have indicated that the amount of probiotics should be at least in the order of 106-107 CFU/g; therefore, as the undergoing depletion of the microorganism proceed along the storage period, the product would be able to exert the healthy benefits such anti-diarrhea, balancing the micro-flora in intestinal track, stimulating the better functioned immune system and, improving lactose intolerance symptoms. Micro-encapsulation is an effect approach to improve viability and stability of probiotic; nevertheless, the microorganism be allowed to be released perpetually and exercise specifically.
In this study, alginate was used as encapsulating material to wrap probiotic via syringe squeezing technique. The results indicated that 2% alginate encapsulation were capable of protecting the probiotics from inactivation by stomach acid and preserved the viability of the order of 6-7 Log value which had been released in the simulated in vitro intestinal environment. Furthermore, Fibersol-2® (difficultly digestible dextrin, DDD) was also included as prebiotics enhance the reproduce capability of probiotics with the significant level above 2% (p<0.05) The conducted experiment indicated that the existence of DDD would allowed the already injured probiotics (due to stomach acid) would recover/reproduce in the intestinal environment from the order of 8.09 Log to 9.32 Log value.
Whereas, it would conclude that alginate is able to consider as a remedy encapsulation material and the extra addition of DDD is a possible option to increase the reproduction rate of probiotics so as to improve the micro-flora distribution and enhance the amount probiotics.
