But remember that oyster sauce, like a lot of other condiments, usually has a best before date and not a use by date or expiration date. Because of this distinction, you may safely use the product for your flavoring needs after the best before date has lapsed if it was stored properly, but try to use before its eat by date.
How to tell if Oyster Sauce is bad, rotten or spoiled?
Practicing proper hygiene and food safety techniques will help prevent foodborne illness.
The quality of the oyster sauce will decline over time with the color getting darker and the flavor getting stronger due to the oxidation process. Thus, peak flavor for oyster sauce is when it is first opened. The first indication that oyster sauce is going bad is usually a separation of liquid from the other ingredients.
Old oyster sauce may experience changes in color, flavor and/or texture but should not be harmful to consume unless a foul odor or a mold develops. If it gets to the point where there is mold or a foul odor, it must be discarded.
There are, of course, certain health risks associated with spoiled foods so always remember to practice food safety and enjoy your foods before their shelf life has expired!
How to store Oyster Sauce to extend its shelf life?
The best way to store unopened oyster sauce is in a cool dark place like the pantry at a constant temperature, away from heated appliances like the stove or dishwasher. Once opened, oyster sauce must be constantly kept in the refrigerator in its original glass container with the lid tightly sealed. If your sauce came in a can, be sure to transfer it to a plastic or glass container before refrigerating.
Some benefits of proper food storage include eating healthier, cutting food costs and helping the environment by avoiding waste.
How long is Oyster Sauce good for when prepared in a dish?
How long does oyster sauce last? That depends. How long does rice last? In general, it will be the longest lasting ingredient in any dish, soaking into the other ingredients. But still, it can only last as long as the quickest expiring ingredient in the dish.
