摘要:
A method and apparatus for retaining closure of shells of raw molluscan shellfish prior to high pressure processing involves positioning of heat-shrinkable band around each individual shellfish. The shellfish is then exposed to heated air of about 300-400 degrees Fahrenheit to 2-3 seconds, a time sufficient to cause shrinking of the band and secure adherence of the band to the shells. To prevent denaturing of raw shellfish the banded shellfish is then immediately exposed to a stream of cold air, about 30 degrees Fahrenheit for 1 second. Cooling of the banded shellfish arrests the heating process and helps retain sensory qualities of the product.

The invention relates to a process for eliminating pathogenic organisms from raw food products, such as raw shellfish, whereby the molluscan shellfish is exposed to hydrostatic pressure of relatively high value, for example between 20,000 p.s.i. to 50,000 p.s.i. for 1-15 minutes. The process is conducted at ambient temperatures, leaving the raw shellfish substantially unaffected, in its desired raw state, such that the pathogenic organisms are destroyed, while sensory characteristics of the raw shellfish remain high. The same process can be used for shucking oysters without any mechanical force. A high pressure processor for elimination of bacteria in raw food products is disclosed.

A sea-going vessel has mounted on its deck a clam processing plant which includes in sequence a steamer, a clam crusher, a seawater washer, a brine separator, an eviscerator and a chill tank. Special valves are constructed to feed and discharge clams from the steamer which prevents the hot high pressure steam in the steamer from being discharged when the valves are open to the steamer interior. The chill tank includes a special construction to minimize the effects of pitch and roll of the deck while the ship is at sea.

Method of preserving clams. This method involves the steps of cleaning a clam, sorting the clam, freezing the clam while the clam is alive, packaging the clam, and cooking the clam. An apparatus for containing clams having a tray having an upper surface and a plurality of defined locations constructed and arranged to receive a clam, the clam deposited in one of the plurality of defined locations, and the tray disposed within a plastic freezer bag.

The invention relates to a method of preserving shellfish using a modified atmosphere which is rich in oxygen and which contains a second main nitrogen component, such as to preserve the live bivalve shellfish and safeguard the quality of said food for as long as possible throughout the marketing and sales process. The shellfish sales packaging must be full and well compacted, for which purpose, the units must be perfectly inserted during the filling operation using a vibrator, such that the bivalve shellfish cannot open their valves and lose intervalvular liquid throughout the sales process. The invention relates to the most popular bivalve on the market in terms of sales and price and, as a result, is of particular interest to the mussel industry.

A process is disclosed by which a clam is extracted from its shell, the viscera is removed from the tongue, the tongue is butterflied and thereafter passed through a conventional tenderizer.

The invention relates to a method of processing crustaceans, live and cooked to cause detachment of shells from crustacean meat. According to the method, live crustaceans are exposed to hydrostatic pressure of relatively high value, for example between 20,000 p.s.i. to 60,000 p.s.i. for 2-5 minutes. The process is conducted at minimal elevated temperatures, in the range of above ambient temperature of 40 degrees to about 110 degrees Fahrenheit, leaving the raw crustacean meat substantially unaffected, in its desired raw state, while the connective tissue deteriorates and the shell detaches from the meat. As a result separating the edible meat from the shell becomes much easier and less time-consuming. Cooked crustacean meat can also be processed under hydrostatic high pressure in the order of 30,000 p.s.i. to 60,000 p.s.i. to eliminate or substantially reduce bacteria in the meat, thereby extending shelf life of the product.
