How to Prevent Freezer Burn in Fish
It is possible to prevent your fish from freezer burn by fixing a few things that we tend to ignore when storing fish in the freezer.
1. Vacuum seal
Once you put your fish in a zip lock bag, use a vacuum seal to suck out as much air as possible before sealing to retain the best quality for long. You can also use a straw to suck out air manually in the absence of a vacuum seal.
2. Keep the temperatures at 0°F
When the freezer is at its lowest temperature, your fish will freeze faster hence preventing the risk of formation of large ice crystals on its surface and therefore retaining its quality better.
Its always advisable to use your frozen fish a month before its expiry, for quality purposes. Therefore ensure that you label the expiry date on the package to avoid over freezing.
4. Glaze with water
Glazing is simply dipping your fish in water then freezing to form a protective layer of ice which prevents the fish from coming into contact with air while in the freezer. The layer also helps to protect the fish from temperature fluctuation hence maintaining its quality whenever the door is opened.
5. Repackage store-bought fish
Once you bring your fish home from the store, remove it from the original packaging it came with and package it afresh. Repackaging saves the quality of your fish in case the original packaging had invisible tears which can allow air in and cause freezer burns. Also, you want to package it keenly (wrap each piece separately) especially if you intend to freeze for longer.
6. Store where its coldest
If you are using any other freezing method apart from the glazing, store your fish at the back of the fridge where temperatures remain constant even when the door is opened.
