It is likely not a matter of "Is it safe?" It is more a matter of will it rise as it should and will it taste as good as it should. The other issue that jumps to mind is ...make sure there are no bugs in the mix. Any item with flour in it has the potential to have small worms or moths in it. They were in the wheat when the was harvested. It probably won't hurt you, but realize it might not be as good as fresh and check from insects.
I don't know what is sodium hydroxide but what I do know is that anything or any food that is past its expiration date is not safe to use.
The expiration date is how long the medication is guaranteed to be potent for. You should be fine to take it past its exp date, just might not work as well.
No it isn't safe. Taking anything past the experation date is unsafe
Because creamed peas contain dairy I would not suggest consuming them beyond the expiration date
Obviously not, otherwise it would not have an expiration date.
It might be, but it is not wise. I would smell it and see if it looks alright.
No I dont recommend eating anything after the Expiration date
Depending on the distance between expiration date and and the current date, organic fruit juices may be safe to eat. The expiration date may also indicate the last day before the juice loses its quality, not the last day it is safe.
The expiration date on most drugs tell you when the manufacturer is guaranteeing it will have the maximum potency. Taking a drug after the expiration date is taking a chance that it won't be as effective as a drug taken within the "guaranteed effective." So, in answer to your question, on the diphenhydramine, no one knows if it is safe. All you can say for sure, is the manufacturer will not guarantee the drug is 100% effective after the expiration date.
Is it safe to eat coconut cream after expiration date
I often do, but only by a day or so. It's cheaper when it's close to date! it depends if u have a good fridge.
There's no way to tell without lab tests. Using it will be up to your discretion.
