Abstract

In this research, the probiotic Streptococcus thermophilus was inoculated into milk as co-culture to produce probiotic cheese. The effects of using Streptococcus thermophilus with other probiotic bacteria on cheese composition, and microbiological viability during 28 days of storage were investigated. Sensorial properties were determined only at 1st and 28th days of storage. The results showed that the use of Streptococcus thermophilus as co-culture in probiotic cheese production did not affect negatively the cheese components. Fat and dry matter properties of cheese weren't influenced by added probiotic bacteria. However, different level of pH, salt and lactic acid were detected. All probiotic bacteria were present in high levels throughout storage of cheeses, above 7 Log cfu.g(-1), threshold required for probiotic activity. Sensory panel showed that the highest average sensory evaluation points were recorded in cheeses made with Streptococcus thermophilus plus Lactobacillus casei, whereas other probiotic bacteria combinations had been affected less in regard to taste or appearance.
