How to Tell If Hoisin Sauce Is Bad? Hoisin Sauce Shelf Life!

A sauce like hoisin may not be as common to you as something like mayo or other household condiments. That’s why it can be trickier to tell if your bottle of sauce has gone bad.

One of the first signs of spoilage is the presence of mold. This happens because of a fungus that can infect your food.

Another sign is a sour smell that happens when the sauce has gone under fermentation from a yeast infection. If your sauce smells or tastes sour, this is the likely reason.

Lastly, you should look at the consistency of your sauce. If it feels rubbery, it has probably gone bad.

This can happen because it has lost most of its water content and become dehydrated as a result.

You can now go out and buy the sauce, safe with the knowledge that you will be able to tell when it happens to go bad.
