Abstract
It has been known that bivalves can be shucked and the flesh can be detached after high hydrostatic pressure (HHP) treatment. In this regard, some patents have been issued. In Japan, one commercial scale shucking of oyster is realized by treating the bivalve at 80 MPa and 40°C. HHP shucking of oyster contributes to reducing the labor cost and the claims from consumers on the contaminated hard shell pieces. In the USA, HHP-shucked oysters receive a good reputation. However, applicability of HHP shucking to other bivalves has not been sufficiently studied and scientific publications of the relevant data have been quite limited. In this study, bivalves other than oyster were subjected to HHP treatment for shucking and flesh detaching.
