Probiotics are dietary supplements containing potentially beneficial bacteria or yeast, with lactic acid bacteria (LAB) as the most common microbes used. LABs have been used in the food industry for many years because they are able to convert sugars (including lactose) and other carbohydrates into lactic acid. They not only provide the characteristic sour taste of fermented dairy foods such as yogurt but act as a preservative, by lowering the pH and creating fewer opportunities for spoilage organisms to grow.
