Kefir yeasts
What is Kefir yeasts?
Kefir yeasts are a group of beneficial fungi used in the fermentation of kefir, a cultured dairy product. They occur naturally in kefir grains, which are a symbiotic culture of bacteria and yeasts.
Kefir yeasts are used in food production to ferment lactose, the sugar in milk, into lactic acid and other compounds that give kefir its distinctive tangy flavor and probiotic properties. Research suggests that consuming kefir may have health benefits due to these probiotics, although the evidence isn't conclusive due to variations in kefir products and individual microbiomes.
When you see kefir yeasts on a label, it indicates the presence of live cultures, similar to those found in yogurt. They contribute to the probiotic content and potential health benefits of the product.
