The differences between frozen seafood and fresh seafood lie in preservation methods, suitable scenarios, and quality performance:

1. Preservation Methods

• Frozen Seafood: Utilizes quick freezing technology to rapidly chill seafood to extremely low temperatures after being caught, inhibiting bacterial growth and extending shelf life.
• Fresh Seafood: Needs to be transported to markets or consumers shortly after being caught, relying on ice or refrigeration for short-term freshness.

2. Quality and Taste

• Frozen Seafood: While quick freezing retains most nutrients, some flavor and texture may be lost during thawing, especially for products stored for long periods.
• Fresh Seafood: Retains its original flavor and texture as it avoids freezing, but quality may degrade quickly if mishandled during transport or storage.

3. Transport and Storage

• Frozen Seafood: Suitable for long-distance transportation, requiring high storage standards but offering a longer shelf life, making it convenient for businesses and consumers.
• Fresh Seafood: Typically used for short-distance transportation, with a shorter shelf life requiring rapid sale or consumption.

4. Suitable Scenarios

• Frozen Seafood: Ideal for processed foods, long-term storage, or bulk purchases, such as for restaurants or supermarkets.
• Fresh Seafood: Preferred by those who prioritize taste, particularly for home cooking or use in high-end dining establishments.

In summary, frozen seafood offers convenience and storage flexibility, while fresh seafood excels in taste and quality for immediate use. Consumers can choose the appropriate type based on their needs and specific scenarios.
