2. Analysis of recent hot issues
1.Can I buy "Headhead Shrimp"?Recent hot searches show that the black hair of shrimp may be due to oxidation caused by improper storage. It is not absolutely spoiled, but it needs to be judged based on the smell and meat quality. If the shrimp body is elastic enough and has no peculiar smell, it is still edible.
2.Is "ice coat too thick" legal?According to national standards, the weight of the ice coating must not exceed 20% of the net weight of the shrimp. Consumers can make preliminary judgments by comparing the "net content" and total weight marked on the packaging.
3.Imported shrimp vs domestic shrimp:In the discussion in the past 10 days, vannamei shrimp (imported) and base shrimp (domestic) have been the most popular. Imported shrimps need to pay attention to quarantine labels. For domestic shrimps, it is recommended to choose brands directly supplied from the place of origin.
3. Step-by-step purchasing skills
Step one: look at the packagingChoose products that are clearly marked with "production date", "shelf life" and "net content", and give priority to shrimp that have been produced recently and are packaged without flatulence.
Step 2: Identify the appearanceAfter thawing, the shrimp body should be bent and firm, and the shrimp shell and meat should fit tightly. If the shrimp body is straight or loose, it may have been frozen and thawed repeatedly.
Step 3: Measure elasticityPress the shrimp meat with your fingers. High-quality shrimp will spring back quickly, while inferior shrimp will leave dents.

| Brand B | High cost performance, direct supply from domestic products | Occasionally, small shrimps are mixed in |
| C brand | Imported shrimp quarantine labels are clear | Price is on the high side |
