Does la choy sweet an sour sauce go bad?

La Choy sweet and sour sauce can last a long time if stored properly, but it can go bad over time. Typically, if unopened, it can be stored in a cool, dark place for up to a year past its expiration date. Once opened, it should be refrigerated and consumed within a few weeks to a few months for the best quality. Always check for signs of spoilage, such as an off smell or changes in texture.
