Abstract

A method for facilitating the removal of the shell of a lobster, crab or shrimp by exposing the lobster, crab or shrimp to pressure for a period of time sufficient to effect detachment of the meat from the shell. Following pressurization, the shell can be easily removed using any available means to provide deshelled raw lobster, crab or shrimp meat.

Claims (14)

1. A method of facilitating detachment of meat from the shell of a lobster, said method comprising:

exposing the lobster to pressure of from 25,000 psi to 50,000 psi for a period of from 15 seconds to 180 seconds at a temperature of between 0° C. and 30° C.

2. The method of claim 1 , wherein the pressure is at least about 30,000 psi.

3. The method of claim 1 , wherein the pressure is maintained for a period of about 60 seconds.

4. The method of claim 1 , wherein said pressure is hydrostatic pressure.

5. The method of claim 1 , wherein the lobster is not exposed to heat treatment or chemical or enzymatic treatment before, during or after said exposing to pressure.

6. The method of claim 1 , wherein the total yield of lobster meat (total weight of claw, tail and leg meat/total green weight of lobster) is at least about 29%.

7. A seafood product comprising the meat of a lobster which lobster has been subjected to the method of claim 1 to facilitate detachment of meat from the shell of said lobster.

8. A seafood product comprising the meat of a lobster which meat is uncooked and has not been subjected to enzymatic or chemical treatment to effect detachment of the shell of the lobster.

9. The seafood product of claim 8 , comprising the meat of a lobster claw with the shell removed, the meat having a yield of at least about 54% (weight claw meat/weight of claw in shell).

10. The seafood product of claim 8 , comprising the meat of a lobster tail with the shell removed, the meat having a yield of at least about 61% (weight tail meat/weight of tail in shell).

11. The seafood product of claim 8 , comprising the meat of a lobster leg with the shell removed, the meat having a yield of at least about 49% (weight leg meat/weight of leg in shell).

12. The seafood product of claim 7 , wherein the meat is detached from the shell in a substantially intact state, without mincing or flaking.

13. The seafood product of claim 7 , comprising the meat of a whole lobster with the shell detached.
