Keep your prawns fresh for a whole month with this simple trick

If you purchase shrimp and immediately put it in the refrigerator, the preservation time will not be long. Following this method will both extend the preservation time and ensure the freshness of the shrimp.


Shrimp is a premium source of high-quality protein that plays a vital role in building and maintaining strong muscles. They also provide essential amino acids that contribute to the synthesis of many vital molecules in the body. With its abundance of Vitamin B12, shrimp helps support the proper functioning of the nervous system. Shrimp also contains various minerals such as zinc, copper, and selenium, which are beneficial for boosting immune function and antioxidant activity.

Whether it’s farmed freshwater shrimp or shrimp caught in the sea, they both have seasonal characteristics and are often difficult to find fresh all year round. This makes many people buy shrimp in large quantities at once to stock up in the refrigerator. Due to the high water content of shrimp, proper preservation is a significant challenge because if not done correctly, the shrimp can lose its original flavor. Therefore, understanding the proper technique for preserving shrimp is essential.

Preservation by freezing with water

Step 1: Clean the shrimp and divide them into small portions, each portion sufficient for one serving.

Step 2: Place the shrimp in a food storage box, pour water into the box, then tightly close the lid and place it in the freezer compartment of the refrigerator for preservation.

Useful tip: To freeze shrimp more quickly and preserve their freshness, you can add a few ice cubes before pouring water and putting them in the refrigerator. This method helps the shrimp freeze more rapidly.

End result: By applying this method, the shrimp will gradually transition to a frozen state, avoiding sudden freezing that can “burn” the shrimp, resulting in discoloration and loss of freshness if frozen for a long time.

When you need to use the shrimp, simply open the lid of the box, add water to thaw and naturally defrost before cooking. This preservation method not only keeps the shrimp fresh but also ensures that the refrigerator does not have any odor, and the preservation time can extend up to one year.

Useful tip: If you do not have a food storage box, you can use a plastic bottle to preserve the shrimp in a similar way.

Preservation of shrimp with ice

Step 1: Clean the shrimp, then put them in a plastic box with a tight-fitting lid.

Step 2: Put an ice cube into the shrimp container and tightly close the lid.

Step 3: Place the tightly closed shrimp container in the freezer compartment of the refrigerator for freezing.

End result: With this method, shrimp can be safely preserved for up to one month. However, thawing the shrimp will take additional time. When preparing shrimp, you should apply cooking methods such as stir-frying, boiling, or steaming to remove any harmful microorganisms that may be present in the shrimp.
