Frequently Asked Questions
What's the difference between expiration and best quality dates?
▼
Soy sauce does not have a strict expiration date but rather a 'best by' date for optimal quality. Over time, soy sauce may darken in color and develop a stronger flavor due to oxidation, but it remains safe to consume as long as there are no signs of spoilage. While expired soy sauce may not taste as good, it is unlikely to cause harm if consumed in moderation.
How can I tell if Soy Sauce Unopened has gone bad?
▼
To check if unopened soy sauce has gone bad, first look for any unusual discoloration or cloudiness. Next, give it a sniff to detect any off or sour odors. Lastly, ensure the texture is smooth and free of any mold growth before consuming.
What are the food safety risks?
▼
Soy sauce, when unopened, is generally safe from foodborne illnesses due to its high salt content and low water activity. However, there is a risk of contamination if the bottle is not sealed properly. To prevent any potential risks, always store soy sauce in a cool, dry place away from direct sunlight and moisture. Avoid using soy sauce that has an off smell, appearance, or taste, as these could indicate spoilage.
What are some pro storage tips?
▼
To maintain the best quality of unopened soy sauce, store it in a cool, dark place like a pantry or cupboard.
