Prebiotic properties of licorice root extracts
MetadataShow full item record
The study objective is to investigate effect of licorice root extract on growth of probiotic microorganisms. As fructan percentage in licorice roots is 27.8–28.8%, this value is sufficient to enable the raw material suitability as a prebiotic ingredient. The licorice root extract (0.1%, 1% and 10% of medium volume) was added to media. The same media without added extract were considered as controls. Effect of the licorice root extract on growth of probiotic microorganisms was studied in 2 commercial probiotic drug Bifiform (Denmark) and Bifidobacterin forte (Russia). Licorice root extract provides probiotic bacteria an opportunity to tolerate acidity/alkalinity gradient of model media well and to decrease their count slower. In vitro studies showed, what 1% extract provides more favorable conditions for microorganisms that 10% one.
