What's the matter with shrimp bitterness?
Recently, the topic of "bitter shrimp" has triggered widespread discussions on social media and food safety forums. Many consumers reported that the shrimp products they purchased had a bitter taste, which even raised concerns about food safety. This article will analyze the reasons for the bitterness of shrimps from a scientific perspective and provide you with a comprehensive answer based on hot data from the entire Internet in the past 10 days.

2. Analysis of the five major causes of shrimp bitterness
1.feed factors: If the feed used in the breeding process contains a high proportion of plant protein (such as cottonseed meal), its gossypol component will cause the shrimp meat to accumulate bitter substances.
2.environmental pressure: Deterioration of water quality (excessive ammonia nitrogen, insufficient dissolved oxygen) will stimulate shrimps to secrete stress substances, and these metabolites may produce a bitter taste.
3.drug residue: Antibiotics (such as oxytetracycline) used illegally in some farms will form bitter taste residues in the shrimp if they do not pass a sufficient withdrawal period.
4.corruption: Improper storage causes shrimp autolytic enzymes to decompose proteins and produce bitter peptides and free amino acids. Testing data shows that the risk of bitterness increases by 300% for shrimp stored above 4°C for more than 36 hours.
5.Variety characteristics: Some special species (such as Macrobrachium rosenbergii) naturally produce bitter substances during the breeding period, which is due to their biological characteristics.
3. Consumer response guide
| Symptom type | security risk | Handling suggestions |
|---|---|---|
| Slightly bitter | low risk | Marinate with lemon juice or cooking wine |
| persistent bitter taste | medium risk | Stop eating and keep sample |
| Bitterness accompanied by off-flavor | high risk | Throw it away immediately and take photos for evidence collection |
4. Latest Industry Trends
According to the latest announcement from the Ministry of Agriculture and Rural Affairs in July, special inspections of aquatic product quality have been launched nationwide, focusing on the detection of chloramphenicol, nitrofurans and other prohibited drug residues. Consumers can scan the QR code to check breeding information through the "Agricultural Products Quality and Safety Traceability Platform".
A well-known seafood brand's stock price fell by 12% in three days due to complaints about shrimp bitterness, reflecting the market's high sensitivity to food quality. Data from e-commerce platforms during the same period showed that sales of "raw food grade" shrimp products surged 180% year-on-year.
5. Scientific purchasing suggestions
1. Observe the shrimp body: the shell and muscles of fresh shrimp are closely connected, and the shrimp head is blue-gray rather than black.
2. Smell the smell: Normal shrimp has a light sea smell. If there is an ammonia smell, it indicates corruption.
3. Touch test: Rapid rebound after finger pressing indicates high freshness
4. Purchase channels: Give priority to products with ASC/MSC certification
Experts remind that if you encounter quality problems, you can retain evidence and complain to the 12315 platform. In the past 10 days, 237 related complaints have been accepted across the country, with a success rate of 92%.
