Itsumo® Freezing

The World's Best

The World's Best

Itumo freezing technology logo

Itsumo tuna is caught and immediately frozen at -90 degrees Celsius using "CAS" technology (Cell Alive System). CAS freezing methodology preserves Itsumo Tuna by employing ultrasonic vibration at the molecular level, thereby preventing ice crystal formation within the cell wall.

-60 degree Celsius Super Frozen Technology maintains the cellular structure, at an atomic level.

Catch and Production

Itsumo procurement (catch), CAS freezing, and ultra-low temperature storage cease all movement at an atomic level within the molecular structure. This unique chain is strictly maintained from vessel, through the supply chain to our customers worldwide. Itsumo frozen tuna is packed in our custom-made B.A.P.-free bag, thereby preventing pathogen contamination both inside and outside of the bag. Itsumo technology allows for simple defrosting in standard refrigerators.
