Abstract

Abstract An edible and hatchable aquaculture product is produced by soaking a quantity of dry brine shrimp eggs in fresh water, then adding an oxidizing agent to the water to dissolve the outer shells of the water-soaked brine shrimp eggs while agitating the eggs and maintaining the temperature of the mixutre below 40° C., separating the resultant denuded cysts from the mixture, rinsing the separated cysts in a neutralizing liquid, and thereafter thoroughly drying the denuded cysts at a temperature below 40° C.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 96 words
The method of producing an edible and hatchable aquaculture product, comprising the steps of soaking a quantity of brine shrimp eggs, consisting of cysts surrounded by outer shells, in water for a time sufficient to saturate the eggs, immersing the saturated eggs in a chlorine type oxidizing liquid medium for a time sufficient to cause the shells of said eggs to dissolve into said medium while maintaining the temperature of said medium below 40° C., separating the resultant denuded egg cysts from said medium, and thereafter drying said denuded cysts at a temperature below 40° C.
Claim 2
Independent Claim 96 words
The method of producing an edible and hatchable aquaculture product, comprising the steps of soaking a quantity of brine shrimp eggs, consisting of cysts surrounded by outer shells, in water for a time sufficient to saturate the eggs, immersing the saturated eggs in a chlorine type oxidizing liquid medium for a time sufficient to cause the shells of said eggs to dissolve into said medium while maintaining the temperature of said medium below 40° C., separating the resultant denuded egg cysts from said medium, and thereafter drying said denuded cysts at a temperature below 40° C.
Claim 3
Dependent Claim 38 words
The method of claim 1 wherein said drying step comprises blow-drying said cysts by placing said denuded cysts in a fine mesh bag, and blowing air through said bag until the cysts in said bag are thoroughly dry.
Claim 4
Dependent Claim 30 words
The method of claim 1 wherein the temperature of said medium is maintained below 40° C. by adding ice to said medium while the shells of said eggs are dissolving.
Claim 5
Dependent Claim 14 words
The method of claim 1 wherein said drying step comprises freeze-drying said denuded cysts.
Claim 6
Dependent Claim 32 words
The method of claim 1 including the step, following said drying step, of packaging said dried cysts in a protective material operative to prevent exposure of said denuded cysts to ultraviolet rays.
Claim 7
Independent Claim 159 words
The method of producing an edible and hatchable aquaculture product, comprising the steps of soaking a quantity of dry brine shrimp eggs in fresh water for a time sufficient to saturate the eggs, thereafter denuding said eggs by adding a solution of sodium hypochlorite to said fresh water in sufficient quantity to provide an alkaline medium capable of dissolving the outer shells of said water-soaked eggs and retaining said eggs in said medium for a time sufficient to dissolve the outer shells of said eggs, agitating the eggs in said medium while maintaining the temperature of said medium below 40° C. during the dissolving of said shells, separating the resultant denuded cysts from said medium by pouring said mixture of cysts and medium through a fine mesh, rinsing the separated denuded cysts in an acidic liquid to neutralize any residual alkaline medium thereon, and thereafter drying said denuded cysts while maintaining the temperature of said cysts below 40° C.
Claim 8
Independent Claim 159 words
The method of producing an edible and hatchable aquaculture product, comprising the steps of soaking a quantity of dry brine shrimp eggs in fresh water for a time sufficient to saturate the eggs, thereafter denuding said eggs by adding a solution of sodium hypochlorite to said fresh water in sufficient quantity to provide an alkaline medium capable of dissolving the outer shells of said water-soaked eggs and retaining said eggs in said medium for a time sufficient to dissolve the outer shells of said eggs, agitating the eggs in said medium while maintaining the temperature of said medium below 40° C. during the dissolving of said shells, separating the resultant denuded cysts from said medium by pouring said mixture of cysts and medium through a fine mesh, rinsing the separated denuded cysts in an acidic liquid to neutralize any residual alkaline medium thereon, and thereafter drying said denuded cysts while maintaining the temperature of said cysts below 40° C.
Claim 9
Dependent Claim 23 words
The method of claim 6 wherein said drying step comprises blow-drying said denuded cysts with air having a temperature less than 40° C.
Claim 10
Dependent Claim 14 words
The method of claim 6 wherein said drying step comprises freeze-drying said denuded cysts.
Claim 11
Dependent Claim 25 words
The method of claim 6 including the step, following said drying step, of enclosing said dried denuded cysts in a moisture-proof ultraviolet proof packaging material.
