Defrosting Instructions

Here are the recommended methods for defrosting bluefin tuna while maintaining its quality:

1.⁠ ⁠Ice Bath Method (Preferred for Superfrozen Tuna)

• Keep the tuna in its vacuum-sealed packaging.

• Prepare an ice bath with a 40/60 ice-to-water ratio.

• Submerge the tuna completely and let it thaw for 30 minutes to 1 hour, depending on thickness.

• Once thawed, remove from the packaging, pat dry, and use within 24 hours if refrigerated.

2.⁠ ⁠Refrigerator Method (Slow Thawing)

• Remove the tuna from its vacuum packaging to prevent bacterial growth.

• Wrap it in absorbent paper towels to collect moisture.

• Place it on a plate in the refrigerator set at a low temperature (below 38°F).

• Change the paper towels every 24 hours. The process may take 2–3 days for complete thawing.

3.⁠ ⁠Saltwater Method (For Superfrozen Tuna)

• Prepare a 5% saltwater solution (e.g., 100g salt in 2 liters of water).

• Submerge the tuna block for 15 minutes.

• Pat dry and refrigerate for 2–3 hours before use.

• Avoid defrosting in warm water or microwaves as these methods degrade texture and flavor.

• Always consume defrosted tuna promptly to ensure freshness and safety.
