Dry yeast can still be used after expiration, but the following points should be noted:

1. Check the appearance of dry yeast: if the color of dry yeast turns dark or lumps appear, it may have deteriorated and cannot be used again.

2. Check the odor of dry yeast: if the dry yeast emits an odor, it may have deteriorated and cannot be used again.

3. Test the activity of dry yeast: put the dry yeast into warm water, if it can expand rapidly and produce foam, it indicates that the dry yeast is still active and can continue to be used.

4. Pay attention to the adjustment of usage: if the expiration time of dry yeast is long, you may need to increase the usage to achieve the same effect.

In short, dried yeast can still be used after expiration, but it needs to be carefully checked and tested to ensure that it is still active and safe for use. If you are not sure whether it is suitable for use, it is recommended to purchase new dry yeast.
