Handling and freezing notes

  • Refrigeration ensures that commercial sauces and condiments stay fresh for a longer period of time. Shelf-stable commercial soy sauce and teriyaki sauce are safe when stored at room temperature after opening. Quality, not safety, is the reason the labels on these products suggest that they be refrigerated after opening. FoodKeeper

What the sources say

FoodKeeper lists soy sauce together with teriyaki sauce and gives an unopened bottle 3 years in the pantry from the date of purchase.1

After opening, it gives soy sauce 1 month in the refrigerator.1

FoodKeeper also explains that shelf-stable commercial soy sauce and teriyaki sauce are safe when stored at room temperature after opening, and that refrigeration keeps them fresh for longer.1

Quality, not safety, is the reason the labels on these sauces suggest refrigerating them after opening, according to the same entry.1

The NDSU Extension food storage guide gives the same 3 years for unopened soy sauce in its list of spices, herbs, condiments and extracts, and says to use it within 1 month after opening.21

Iowa State University Extension includes soy sauce in its list of opened condiments kept in the refrigerator and gives it 1 month after opening.3

So all three sources give 1 month once the bottle is open, though only FoodKeeper and Iowa State tie that month to the refrigerator.123
