Characteristics of Fresh Frozen Shrimp
After harvesting, shrimp are typically immediately placed in boxes with ice to preserve freshness until processing. However, this method is not entirely risk-free. There is a possibility of shrimp becoming damaged if the ice melts during transport. This phenomenon is called freezer burn.
Freezer burn occurs when the surface of frozen food oxidizes due to open packaging, resulting in a change in color. This can also happen to frozen shrimp. If you see signs of freezer burn on shrimp, it’s best not to choose that shrimp.
No Black Spots
One sign of fresh and high-quality shrimp is the absence of black spots on the shell. Although frozen shrimp with black spots are not necessarily spoiled or rotten (it’s a natural reaction in shrimp and safe to eat), some sellers use preservatives like sulfites to prevent this. However, note that sulfites can trigger allergic reactions, so be cautious when choosing shrimp preserved with this ingredient.
