Processed in house, our Proton-frozen wild, sushi grade Ahi is a natural alternative to frozen saku tuna.

Proton freezing is an emerging technology and we are one of only few companies in the U.S that are utilizing it. We start with wild-caught Eastern Pacific Ahi, from which we cut 1lb portions to freeze in our Proton freezer. Proton freezing combines an environment of evenly distributed electromagnetic waves and cold air. This quick freeze method reduces ice crystal formation and reduces cell membrane damage. As a result, fish looks just like fresh if used within 30 days of purchase.

Having been frozen at the peak of freshness, each portion is vacuum packed and stored in our super freezer in order to maintain color and quality of flavor. Unlike most frozen tuna sold in the U.S., our Proton-frozen Ahi is not CO-treated. Because of this, its signature red color will naturally turn brown if left in a traditional home freezer for more than a few months.

Our Proton-frozen Ahi is packed skinless and boneless with bloodline out, making it a convenient option to buy now and enjoy later as sashimi or sushi maguro. Please note that because portions are hand cut, they will vary in shape!
