Can I eat yoghurt frozen?

Yes, it is okay to eat it frozen.
Freezing yoghurt does not affect the effectiveness of the probiotics.

Probiotics enter a dormant state at temperatures as low as -60℃.
When frozen, probiotics become temporarily inactive but reactive upon thawing.

However, please note that repeated freezing and thawing may destroy some probiotics.
There is no exact expiration date for frozen yoghurt, but it is recommended to consume it by the expiration date if possible.

You may consume it slightly beyond the expiration date, but it is advisable to eat it as soon as possible.
