Expiration & Storage Tips
When does black bean sauce expire?
Black bean sauce, when unopened, can last up to two years past the printed date on the package if stored correctly at room temperature. After the seal is broken, its shelf life is substantially reduced, but can still last between 6 months and 1 year in the refrigerator. However, if you freeze it, you can expect it to last indefinitely so long as the sauce is kept at a steady 0 degree Fahrenheit.
How do you tell if black bean sauce is bad?
Black bean sauce has a strong, unique aroma to begin with, so sniffing it might not be the best way to tell if it's gone bad because it could be easily confused with its natural pungent smell. Instead, look for changes in its usual dark brown color or any signs of mold. If you notice mold or if the sauce starts to develop an extremely unpleasant smell, it's best to discard the bottle. Also, if the sauce develops a very watery consistency, it might be a sign that it's starting to spoil.
Tips for storing black bean sauce to extend shelf life
• After opening, always store the sauce in the refrigerator to prolong its life. A constant cooler temperature slows down the growth of bacteria.
• Use a clean utensil every time you scoop out sauce to prevent contamination.
• You can freeze the black bean sauce in small portions in airtight containers or sealable plastic bags. This way, you only need to defrost the amount you need. When ready to use, just transfer it to the fridge to thaw for a few hours.
• Keeping the black bean sauce away from direct light and heat can help maintain its quality and extend its life, even when unopened.
