Strict Standards for Export Sashimi-Grade Ocean Tuna
Original Freshness and Ruby Red Color of Ocean Tuna Meat
The core factor determining the value of export ocean tuna is its freshness suitable for raw consumption. The fish meat must possess a characteristic deep red color, showing no signs of bruising or discoloration. When chefs slice it thinly for sashimi, the ocean tuna slice must appear translucent, tender, and melt-in-your-mouth without being mushy.
To preserve these characteristics, the handling process from the moment the tuna is brought aboard the vessel must be highly professional. Fishermen perform bleeding and gutting according to Japanese methods, ensuring the tuna meat retains its elasticity and is absolutely safe for raw consumption.
Ultra-Deep Freezing Technique for Sashimi-Grade Ocean Tuna
A critical element for raw food products is ultra-deep freezing technology. Ocean tuna are immediately frozen at temperatures as low as -60 degrees Celsius. This process locks in cell integrity, prevents microbial growth, and ensures that when thawed, the tuna retains its fresh sashimi flavor.
