The present study aimed to develop a novel dairy product by combining Bifidobacterium lactis subsp. lactis BB 12® with proven probiotic properties with Enterococcus faecium K67E3 and Enterococcus durans K63E1, which possess potential probiotic properties. Physicochemical, textural and viscosity properties, microbiological, and sensorial attributes of set-style probiotic yoghurt-like products were analysed during the storage at 4 ◦C for 21 days. The starter culture type had an effect (p < 0.05) on physicochemical, textural and viscosity properties of probiotic yoghurt-like products. High probiotic viability was determined in all samples except for the LD sample containing a combination of Bifidobacterium animalis subsp. lactis BB-12® and Enterococcus durans K63E1. The use of starter culture combination containing Streptococcus thermophilus, Bifidobacterium animalis subsp. lactis BB-12® and Enterococcus durans K63E1 (TLD) in the probiotic yoghurt-like product yielded better textural parameters, apparent viscosity, and improved sensory attributes. Although Enterococcus genera are not thought to be completely safe for use in human food so far, as a result of the research findings, it would be of interest for the dairy industry in the development of novel probiotic dairy products.
