Expiration & Storage Tips
When does bonito flake expire?
Like many dehydrated foods, bonito flakes have a long shelf life. Unopened product can remain fresh for up to two years. Printed expiration dates should be adhered to but can often be exceeded if the package isn't opened. Once you open the package, they should be used within 1-2 months for optimal flavor, though they won't necessarily spoil for several months. These flakes can also be frozen for up to 6 months.
How do you tell if bonito flake is bad?
Determining if bonito flakes have gone bad involves checking their appearance, smell, and taste. Healthy flakes should retain their pinkish-brown hue and have a robust, smoky aroma. If they appear dull or discolored, that's a warning sign. If you notice a stale or off-smell or taste, trust your senses and discard the unused portion.
Tips for storing bonito flake to extend shelf life
• Keep them in an airtight container, and ensure the lid is securely fastened after each use.
• Store in a cool, dark place such as a pantry or a drawer where direct sunlight and heat cannot degrade the flavor.
• Consider vacuum sealing the package or transferring to a smaller container as you use them to keep excess air out.
• For longer storage, freeze them. Ensure they are stored in airtight containers or freezer-friendly bags to prevent freezer burn. To use, simply remove from the freezer and let it return to room temperature.
