The goal of this work was a study the influence of food and beverages on the viability and growth of probiotic bacteria. The influence of food and beverages was tested on monocultures of Lactobacillus acidophilus, Bifidobacterium breve and mixed culture of probiotic microorganisms. In the experimental part, probiotic cultures were incubated in selected foods and beverages. After that they were tested in a model conditions of digestive tract. In some probiotic cultures, growth of viable cells during incubation in the digestive tract was observed. The increase of probiotic cells was showed predominantly in foods that contained higher levels of sugars and fats or a suitable combination. Their increase was up to four times in some cases. Based on the results, mixed probiotic cultures aren’t surprisingly exhibited better survival and maintain sufficient amount of viable cells even during the digestive process. Moreover, probiotic microorganisms could be recommended to consumption during meals better than just with a beverage.
