What is CAS freezing?

In the case of food that is frozen using an ordinary quick freezer, the flavor and trace elements are lost with moisture as “drips” while defrosting because a certain amount of cell damage is inevitable due to the expansion of the ice crystals. Using CAS prevents such expansion of the ice crystals by using a special technology to vibrate the water molecules, and freezing the food while maintaining a uniform temperature from the surface to the center, so that the fresh taste is retained as-is without damage to the cell tissues.

The report of comparative analysis conducted by the Taste & Aroma Strategic Research Institute

According to the analysis conducted by the Taste & Aroma Strategic Research Institute, which is an consulting organization analyzing and digitizing palate, generally, the CAS frozen scallops have a rich flavor than the regular frozen scallops.


This might be happened that because the CAS freezing process minimizes cell damage, therefore the scallops frozen with CAS would not loose not only umami flavor, but also other components. “Senrei CAS FRESH Scallops” are well accepted with their high quality by sushi restaurants, upgrade hotels, and other foodservice operators in Japan and overseas. “Senrei CAS FRESH Pacific Saury Fillets” was launched in 2016, which offer the freshness and excellent flavor same as when they were harvested. By freezing them, we solved the anisakis issue. The products are evaluated highly as safe and easy to adopt in addition to their freshness and excellent taste.
