Cereal-based vegan desserts as container of potentially probiotic bacteria isolated from fermented plant-origin food

Abstract

The aim of this study was to assess the possibility of using selected bacterial strains (lactic acid bacteria – LAB) isolated from traditional fermented plant-origin food, to produce potentially functional (probiotic and/or synbiotic) cereal-based vegan desserts. The scope of the study included: optimization of the recipe and fermentation conditions of cereal raw materials, taking into account the an adequate concentration of the number of probiotic bacteria in the product at a minimum level of 6 log CFU g−1), an accepted sensory quality of the final product after the fermentation process and estimation of microbiological and sensory quality of developed products after 21 days refrigerated storage. The level of vitamin B12 in fresh products and after refrigerated storage was also determined. The results showed that it is possible to develop safe, potentially functional cereal-based vegan desserts with an appropriate number of LAB bacteria, accepted sensory quality and content of vitamin B12.
