Testing the Viability of Probiotic Microorganisms in Different Dairy Products

By boosting immunity, increasing gut microbiota, and preventing a number of illnesses, probiotic bacteria are essential for improving human health. But for them to be effective, food products must be sufficiently viable until they are consumed. The viability of probiotic strains such Lactobacillus acidophilus, Bifidobacterium spp., and Lactobacillus casei in various dairy matrices, such as yogurt, milk, fermented milk, and ice cream, during storage is assessed in this study. Colony-forming units (CFU) were calculated using standard microbiological methods in addition to physicochemical analyses including pH and acidity. The findings show that, in comparison to non-fermented items, fermented dairy products, such as yogurt and fermented milk, offer superior protection and higher survival rates. The study emphasizes how crucial bacterial strain selection, storage conditions, and product composition are to preserving probiotic vitality.By boosting immunity, increasing gut microbiota, and preventing a number of illnesses, probiotic bacteria are essential for improving human health.
