The Secret to Keeping Shrimp Fresh for Up to Six Months: Don’t Refrigerate, Try This Instead

10 September, 2024

Shrimp is a type of seafood that is very popular in Vietnamese cuisine. Despite being nutritious, few know how to store shrimp properly to maintain its freshness.

Seafood is always an essential part of delicious meals, featuring distinct flavors and high nutritional value. Among seafood dishes, shrimp often makes the most appearances on family dinner tables due to its savory taste and sweet, chewy meat.

However, if you accidentally buy more shrimp than necessary, proper storage is crucial to ensure its quality for later consumption. A common mistake is to place shrimp directly in the refrigerator, which not only diminishes the meat’s quality but also causes it to lose its sweetness and chewiness. So, what is the most effective way to store shrimp?

Seafood is an essential part of any delicious meal, offering distinct flavors and high nutritional value.

Preserving Shrimp Using the “Sugar Coat, Seal, and Freeze” Method

A simple and effective way to preserve shrimp is to “coat it with sugar, seal it tightly, and freeze it. Even after six months, the shrimp will remain fresh and tasty.”

Step 1: Prepare the Shrimp

Thoroughly rinse the shrimp under cold running water to remove any impurities. Depending on your preference, you may leave the heads and shells on or peel them off.

Step 2: Coat the Shrimp with Sugar

Sprinkle a thin layer of granulated sugar over the shrimp. Sugar has hygroscopic properties, which help retain moisture during freezing and prevent ice crystal formation. Use just enough sugar to avoid altering the shrimp’s flavor, ensuring an even coating across the entire surface.

Step 3: Store the Shrimp

Place the shrimp in a ziplock bag that is appropriately sized for the quantity of shrimp to minimize air exposure. Remove as much air as possible to inhibit bacterial growth and maintain freshness. Store the bag in the freezer at a temperature below -18°C, which is the ideal temperature for long-term shrimp preservation while maintaining its flavor and nutritional value.

This method not only prolongs the freshness of the shrimp but also retains moisture, especially preventing the heads from turning black. Additionally, when thawed, the shrimp will remain as fresh as if it were just caught. Another simple method is to trim the shrimp’s whiskers, place them in a sealed bottle of mineral water, and freeze.

Frequently asked questions

A unique method to preserve shrimp for long periods is by using salt and rice. This process involves layering shrimp with salt and rice, and then sealing it in an airtight container. This traditional technique can keep shrimp fresh for up to six months.

The salt acts as a natural preservative, drawing out moisture from the shrimp and creating an environment inhospitable to bacteria. The rice helps to absorb any remaining moisture and maintain the dryness required to keep the shrimp from spoiling.

Refrigeration only prolongs the shelf life of shrimp by a few days. This salt and rice method offers a much longer preservation period, making it a cost-effective and convenient option for those who want to stock up on shrimp or enjoy it throughout the year.

Coarser salts, such as sea salt or kosher salt, are recommended as they have larger grains that can absorb moisture more effectively. As for rice, it is best to use uncooked, regular grain white rice. Avoid instant or flavored rice varieties.

First, ensure the shrimp is fresh and cleaned thoroughly. Then, prepare a container by layering the bottom with salt, followed by a layer of shrimp, and then a layer of rice. Repeat these layers until all shrimp are used, ending with a final layer of salt. Seal the container tightly and store it in a cool, dry place. After a month, the shrimp will be ready for consumption and can be cooked as desired.
