Instructions on how to preserve dried fish for the longest time
To prevent dried fish from getting moldy and losing its flavor, storage conditions are extremely important. There are 4 popular methods of preserving dried fish that you should refer to:
Store in the refrigerator
Temperature and humidity are the two leading factors affecting the fermentation and mold growth of food. Therefore, maintaining dried fish at low temperatures is an effective way to extend its shelf life. The refrigerator's cool compartment has a temperature ranging from 5-10 degrees Celsius, which is very suitable for preserving dried fish. The steps to preserve dried fish in the refrigerator are as follows:
- Step 1: Put the dried fish in a plastic bag or zip bag to ensure it is airtight. If it is a plastic bag, you should vacuum or squeeze out all the air before tying the bag tightly to limit oxygen. You can use a straw or a vacuum cleaner.
- Step 2: Place the bag of dried fish in a plastic container with a lid or a clean glass container. This will prevent the bag of fish from being crushed or torn by other foods in the refrigerator.
- Step 3: Place the dried fish container in the refrigerator, where the temperature is between 5-10 degrees Celsius. Avoid placing it in the refrigerator door because this is the area where the temperature is usually the highest and most erratic.
Preserving dried fish this way, you can safely “store” fish for 3-4 weeks. If your family has the habit of buying 1 time to use gradually for the whole month, this is the most suitable way to preserve dried fish.
Store in refrigerator/freezer
For families using dried fish for a longer period of time, storing it in the freezer or industrial freezer is a reasonable choice. At -18 degrees Celsius, all microbial activity is completely inhibited, storing dried fish in the freezer can extend its shelf life to several months with almost unchanged quality.
The process of storing in the freezer is similar to storing in the refrigerator:
- Vacuum dry fish with specialized packaging bags/film.
- Put the vacuum-sealed fish bag into a sealed container.
- Place the fish box in the freezer or refrigerator at -18 degrees Celsius.
To use, remove the dried fish from the freezer, transfer to the refrigerator or leave at room temperature to thaw. Do not use a microwave to thaw dried fish because it will soften the fish and reduce its quality.
A little tip when preserving frozen dried fish is to divide the fish into small portions, just enough for one cooking session, take as much as you need. This will help you avoid having to defrost a large bag every time you want to eat dried fish, avoiding waste.
Vacuum
Vacuum technology can be said to have revolutionized the food preservation industry worldwide. By completely removing air and oxygen inside the packaging, the living environment of bacteria and mold is also destroyed. Vacuum-packed dried fish will be as fresh as new for a long time.
To vacuum dry fish, you will need:
- Prepare PA/PE plastic bags or specialized packaging film. These types of packaging will withstand high temperatures and prevent the penetration of oxygen and water vapor very well.
- Put the dried fish into small portions into each bag.
- Use a household vacuum cleaner or a handheld vacuum cleaner to suck out the air in the bag. The vacuuming process only takes 10-15 seconds for 1 bag, so you will save a lot of time. If you cannot afford a machine, manual vacuuming with a straw is also simple and convenient.
- Close the bag tightly, stick a stamp, note the packaging time and expiration date of about 1-2 months on the outside of the bag for easy tracking.
- Store vacuum-sealed bags of dried fish in a cool, dry place or in the refrigerator for best results.
Store under normal conditions.
Storing dried fish under normal conditions should only be applied when it is consumed within 1-2 weeks or the refrigerator is overloaded with no more space. When storing at room temperature, you need to note:
- Put dried fish in a sealed bag or tightly sealed box to limit exposure to air and insects.
- Store the fish bag/box in a cool, dry place, preferably below 30 degrees Celsius. Avoid leaving the dried fish in the sun or near heat sources such as stoves or ovens.
- To absorb moisture from dried fish, you can put a spoon in the bag/box. silicon gel. However, this is only a temporary solution, long-term preservation with desiccant is not a good way.
- Check the fish regularly every 5-7 days. If the fish is soft, moist, or sticky, take it out to dry in the sun again or eat it immediately.

- Temperature and humidity in cold storage must be strictly controlled and stable. The temperature should be maintained between 10-15 degrees Celsius and humidity below 30-40% to preserve dried fish for 6-9 months.
- To preserve dried fish for 12 months, the cold storage needs to maintain the temperature at 0-5 degrees Celsius and humidity below 30-40%.
- Dried fish should be placed on shelves in a reasonable manner. Avoid placing fish directly on the cold storage floor to avoid moisture.
