What Makes Soy Sauce Packets Spoil?

Soy sauce packets can spoil if they are unused for a very long time. The packaging may degrade, allowing bacteria and dirt to enter and cause mold, odd flavors, and more.

Direct sunlight and heat can also affect your soy sauce packets because they can encourage bacterial growth.

You may even notice some crystals or white mold-like pieces floating in your soy sauce packet, which means that the soy sauce is not good anymore.

Moreover, heat and light can make the packaging degrade faster. You may be unable to use the soy sauce packet if the package breaks from the heat.
