Abstract

The experiments were carried out to find how the processing of ascidian (Halocynthia roretzi) was affected by the frozen storage. The quality of ascidian which takes the shell-on was changed quickly in the frozen storage. The causes of the change were as follows: 1. the damage caused by the ice crystal in the muscle, 2. a lot of drips after thawing, 3. the discoloration of the muscle after thawing. On the contrary, the quality of ascidian which takes the shell-off was even better in color, texture, yield and drips after 60 days of the frozen storage. But the muscle was blackened after that.
