Does freezing yogurt destroy or alter the effectiveness of the live cultures?
You can freeze a cup of yogurt. A cup of yogurt that has been frozen and thawed will have a different look and texture than fresh yogurt. The cultures become dormant when frozen, but once thawed either in the refrigerator or by your body heat when ingested; they will become live and active once again. There will be a few cultures that do die, but there are so many billions in our products, that it is truly insignificant.
