Proton-Frozen Farmed Sashimi Grade Pacific Bluefin Tuna Belly (Chutoro)
This product is available during these seasons:
The term chutoro refers to the belly area of a tuna along the side of the fish between the akami (red meat) and the toro (pink fatty tuna). It is a medium fatty cut of tuna that is often preferred because it is fatty, but not as rich as toro, which is the fattiest section.
Our sushi grade bluefin chutoro is hand cut in house from whole “ranched” Pacific bluefin tuna (Thunnus orientalis). This capture-based farming method starts with the harvest of smaller wild-caught tuna during a short time of the year. Fish are then transferred to ocean pens off the coast of Mexico where they are fed until time of harvest, which results in a much higher fat content that strictly wild tuna.
Each frozen/vacuum packed piece is approximately 11 oz each. Proton-freezing our chutoro maintains its sashimi quality. This quick-freeze technology combines evenly distributed electromagnetic waves and cold air to reduce ice crystal formation and cell membrane damage. Taste and texture are preserved naturally, without any additives or chemicals. Color is also comparable to fresh if fish is properly stored and defrosted.*
*Certain species, like tuna, naturally turn brown once exposed to air or if stored in a traditional freezer. Proton freezing technology slows this process but does not prevent it. For best results, we recommend placing proton frozen tuna in the coldest part of your freezer and storing for no more than 7 days. When ready to eat, slowly defrost in refrigerator and consume within same 24 hours.
