1. Look at the concentration

Usually, you can judge whether soy sauce has gone bad by looking at its concentration.

You can also tell whether the soy sauce has gone bad by looking at its color. Soy sauce that has not gone bad is mostly reddish brown or tan and has a certain luster. If you find that the color of the soy sauce is dark, it means that it has gone bad.

5. Taste

You can also judge whether the soy sauce has gone bad by its taste. You can take a few drops of soy sauce and put it in your mouth to taste it. If it tastes delicious and the saltiness is moderate, it means it has not gone bad. If it has an odor or is too salty, it means it has gone bad.
