Seafrozen and Landfrozen are the main methods of seafood freezing processing. Primarily distinguished by where and how quickly the freezing process occurs. These differences significantly impact the quality and texture of the seafood.

Landfrozen
Definition: Seafood is preserved with ice or refrigeration after catch, then transported to onshore processing plants for freezing.
Key Features:
- Delayed Freezing: Freezing may occur days after harvest, leading to gradual freshness decline.
- Standard Freezing: Typically frozen at -18°C to -25°C, forming larger ice crystals that may affect texture.
- Cost-Effective: More affordable for mass-market consumption.
Seafrozen
Definition: Seafood is select and flash-frozen directly on the fishing vessel shortly after catch.
Key Features:
- Immediate Freezing: Frozen within hours of capture, preserving peak freshness.
- Advanced Technology: Uses Individual Quick Freezing (IQF) or block freezing to minimize ice crystal damage to cell structures.
- Superior Quality: Thawed seafood retains a texture and flavor close to fresh, with minimal nutrient loss.
