The process of preparing frozen prawns starts right after they are caught. As soon as the prawns are harvested from the sea, they are immediately placed in ice or chilled water to maintain their freshness. This helps in minimizing the growth of harmful bacteria and preserving the quality of the prawns.
Once the prawns are brought to the processing facility, they undergo various steps to transform them into the frozen delicacy that we find in supermarkets and seafood markets. The first step involves sorting and grading the prawns based on their size and quality. This ensures that only the best prawns make it to the packaging stage.
After sorting, the prawns are carefully washed to remove any dirt, sand, or impurities from their surface. This step is crucial to maintain the cleanliness of the prawns and ensure food safety. Once cleaned, the prawns are ready to be processed further.
The next step in preparing frozen prawns is the removal of the shell or exoskeleton. This is usually done by hand or by using specialized machines. Removing the shell allows for easier consumption and ensures that the prawns can be quickly. Some frozen prawns may also come deveined, where the digestive tract of the prawn is removed to enhance the dining experience.
Once the prawns are shelled, they undergo a process called glazing. Glazing involves coating the prawns with a thin layer of ice or a protective glaze made from water and additives. This layer acts as a barrier and prevents the prawns from drying out during the freezing process. It also helps maintain the prawns’ texture and flavor once they are thawed and cooked.
After glazing, the prawns are individually quick frozen (IQF). IQF is a freezing method where each prawn is individually frozen at extremely low temperatures. This technique ensures that the prawns freeze quickly, preserving their freshness and taste. IQF freezing also prevents the prawns from sticking together, allowing consumers to easily remove the desired amount without thawing the entire package.
Once the prawns are IQF frozen, they are usually packaged in sealed bags or boxes to maintain their quality and to prevent freezer burn. The packaging is often designed to be freezer-friendly, ensuring that the prawns remain intact and protected from moisture and air inside the freezer.
Now that the prawns are prepared and packaged, they are ready to be distributed and sold to consumers. Frozen prawns can be easily stored in the freezer for several months without compromising their taste or quality. This is why they have become a go-to option for those who enjoy seafood but may not have access to fresh prawns regularly.
In conclusion, frozen prawns undergo several essential steps before they are sold to consumers. From sorting and cleaning to shelling and glazing, each step helps maintain the quality and taste of the prawns. So next time you enjoy a delicious dish made with frozen prawns, you’ll have a deeper appreciation for the careful preparation that goes into bringing these delightful and convenient seafood options to your plate.
