Do freshwater prawns freeze well?
Yes, the Department of Food Science at Mississippi State University has conducted numerous studies on the shelf life of prawns frozen many different ways. It is best to freeze prawns with heads removed and tail shell still attached. If prawns are frozen in a conventional freezer in a block of ice the texture, flavor, and overall quality of the product will not change for approximately 6 months. If prawns are individually quick frozen (IQF), in a freezer which uses either gaseous nitrogen or carbon dioxide to quick freeze, the texture, flavor, and overall quality of the product will not change for approximately 9 months. Prawns tails frozen for more than one year with either method will have slightly softer texture, however the flavor will not change.
