Probably. Unless it has separated from homogenized to clear liquids and solids. I use separated buttermilk anyway . It makes WAY tangy biscuits. Just watch out for mold .
yes it can bc even if it is unopened it still has a experation date and it can still go bad! yes it can bc even if it is unopened it still has a experation date and it can still go bad!
Possibly. It depends on how long after the date it is, and if any exposure still happened.
If it has been unopened and still looks good I would still use it
buttermilk can last two weeks, but if it is opened it is best to use on the first week. although even after the expiration date you can still using for baking.
The toothpaste will have an expiration date on it somewhere. That date is likely past. If it has been unopened, it may still be usable though.
Yes
The expiration or best-use-by dates are for unopened packages.
Yes. As stated before. The use by date is a "best used by" date. You can eat this product after this date. Longer if the bag has not been opened yet.
you could but it has an expiry date for a reason
Very relevant. The expiry date is for unopened products, opened ones go worse even faster.
i wouldn't use it since it has milk
can you use an unopened can of tomato paste if it expired 4 months prior
