4. Save status analysis
Knowing how shrimp is stored can also help determine freshness:

| Cryopreservation | 1 month | Eat immediately after thawing |
5. Things to note when purchasing
Based on recent shopping experiences that have been hotly discussed by netizens, the following suggestions are summarized:
1.Choose formal channels: Give priority to large supermarkets or reputable seafood markets. These places usually have stricter quality inspection standards.
2.View production date: Packaged cooked shrimp must be marked with a clear production date and shelf life. For bulk shrimp, you can ask the merchant for the purchase time.
3.Observe the sales environment: Make sure the shrimp is stored at a suitable temperature and away from direct sunlight or high temperature environments.
4.Be wary of over-processing: Some merchants may use chemicals to maintain the appearance of shrimps, but you need to be wary of shrimps that are too "perfect".
6. Healthy eating suggestions
According to recent recommendations from nutrition experts:
1. Cooked shrimp should be heated thoroughly before consumption. Even if you purchase pre-cooked products, it is recommended to reheat them.
2. Heavy metals tend to accumulate in the shrimp head, so it is recommended to remove them before eating.
3. People who are allergic to seafood should avoid eating it, and children should try a small amount when eating it for the first time.
4. Eat it with vegetables rich in vitamin C to help absorb iron.
7. Analysis of common misunderstandings
In response to recent misconceptions on the Internet, we would like to specifically clarify:
1.Do shrimp lines have to be removed?The shrimp thread is the digestive tract of the shrimp. It is recommended to remove it but it is not absolutely necessary. It does not affect safety after cooking.
2.Are blackhead shrimps necessarily not fresh?Not entirely correct. The heads of some shrimp species are darker in color and need to be judged in conjunction with other indicators.
3.Are frozen shrimp not as good as fresh shrimp?High-quality quick-frozen shrimp are processed immediately after being caught, and their freshness may be better than "fresh shrimp" transported over long distances.
By mastering these judgment skills, you can easily choose fresh and delicious cooked shrimp. Food safety is no small matter. I hope that the introduction in this article can help you enjoy delicious food while also protecting the health of your family.
