Does Freezing Yogurt Kill the Cultures?

Many consumers choose frozen yogurt as a healthy alternative to ice cream.

Live Culture Frozen Yogurt Standards

Merely freezing yogurt does not kill its cultures.Merely freezing yogurt does not kill its cultures.
It is normally lower in fat than ice cream, comes in appetizing flavors, and can be made into shakes and sundaes. The freezing process itself does not kill yogurt cultures but other steps might.

The National Yogurt Association (NYA) guidelines stipulate that frozen yogurt that carries its seal stating "Live & Active Cultures" has to be made from fermented and pasteurized milk that contains conventional yogurt cultures to create proper levels of acidity.

Freezing Effects on Cultures

Freezing yogurt merely throws the cultures into a dormant, inactive state that ends when the yogurt is warmed through consumption. After being eaten, it has the same benefits as refrigerated yogurt.

Considerations

Some products marketed as frozen yogurt are imposters. These mixtures are frequently unfermented or contain yogurt that has been heated, which kills the active cultures. To be sure frozen yogurt is authentic, be sure it has the NYA seal on the package.
