Summary: Plant-based milk substitutes are the most widespread plant-based alternatives today. Their biological value can be increased by fermentation and the activity of lactic acid bacteria. In this study, effect of temperature (1–8 °C, 20 °C and 37 °C) and short-term storage (up to 18 days) on Lactibacillus rhamnosus LGG (Chr. Hansen, Hoersholm, Denmark) and Bifidobacterium BB-12 (Chr. Hansen) growth and on the quality characteristics (titratable acidity, pH, dry matter content) of model almond-coconut-strawberry probiotic beverage was evaluated. Higher storage temperatures resulted in a significant (p < 0.05) increase in titratable acidity and viable cell counts to values above 109 CFU∙ml-1, while pH and dry matter content decreased significantly (p < 0.05). On the contrary, viable cell counts of Lb. rhamnosus and Bifidobacterium sp. varied slightly around average values of 5.1 × 106 CFU·ml-1 and 8.1 × 106 CFU·ml-1, respectively, during refrigerated storage. In conclusion, the results showed that both bacterial strains have sufficient potential for industrial production of plant-based beverages, the production of which will contribute to the sustainable development of food production and ensure food security.
