Country time lemonade good for deactivating yeast brew?

Any of the ingredients in this good for killing/deactivating yeast cells?

No. Adding things to cider, except for the proper amount of potassium sorbate once it's completely clear and racked off of the lees, won't stop fermentation.

You can add flavorings once you've stabilized, though.
