Abstract
Abstract Fresh shrimp are stored in flake or crushed ice containing a moisture binding phosphate from the time that they are harvested until they are processed, including both aboard the fishing vessel and in the processing plant. An effective amount of sodium tripolyphosphate, Na 3 P 5 O 10 is admixed to water as it is delivered to an ice making machine. The treated ice and the shrimp are introduced together into a storage receptacle. The ice melts as it cools the shrimp, to in that manner bring the moisture binding phosphate into contact with the shrimp meat. It is preferred to use flake ice which contains about one to two percent (1.0-2.0%) by weight of sodium tripolyphosphate, Na 3 P 5 O 10 .

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
87 words
A method of treating shrimp aboard a fishing vessel to reduce the amount of moisture and nutrient loss from the shrimp during storage aboard the vessel and during processing, comprising: catching the shrimp and then promptly storing the shrimp as harvested aboard the vessel in ice particles which contains an amount effective to reduce moisture and nutrient loss of a moisture binding phosphate compound, so that as said ice melts to cool the shrimp the shrimp will be wetted by water containing the moisture binding phosphate compound.
Claim 2
Independent Claim
87 words
A method of treating shrimp aboard a fishing vessel to reduce the amount of moisture and nutrient loss from the shrimp during storage aboard the vessel and during processing, comprising: catching the shrimp and then promptly storing the shrimp as harvested aboard the vessel in ice particles which contains an amount effective to reduce moisture and nutrient loss of a moisture binding phosphate compound, so that as said ice melts to cool the shrimp the shrimp will be wetted by water containing the moisture binding phosphate compound.
Claim 3
Dependent Claim
9 words
The method of claim 1, comprising using flake ice.
Claim 4
Dependent Claim
15 words
The method of claim 1, comprising using ice containing an effective amount of sodium tripolyphosphate.
Claim 5
Dependent Claim
16 words
The method of claim 1, comprising using flake ice containing an effective amount of sodium tripolyphosphate.
Claim 6
Dependent Claim
16 words
The method of claim 1, comprising using ice containing about 1.0-2.0% of sodium tripolyphosphate, by weight.
Claim 7
Dependent Claim
17 words
The method of claim 1, comprising using flake ice containing about 1.0-2.0% of sodium tripolyphosphate, by weight.
Claim 8
Dependent Claim
19 words
The method of claim 1, further comprising conveying the iced shrimp without washing from ice storage to a cooker.
Claim 9
Independent Claim
122 words
A method of treating shrimp while in the shell to reduce moisture and nutrient loss, comprising: delivering water to a flake ice machine, admixing an amount effective to reduce moisture and nutrient loss of a moisture binding phosphate compound with the water while delivering the water to the flake ice machine, so that such compound will be incorporated into the ice, resulting in colder ice with a greater cooling capacity than plain water ice, and collecting flakes of ice from such machine; mixing such flake ice with shrimp within a storage region aboard a fishing vessel, as such shrimp is caught, said mixed ice and shrimp resulting in shrimp being wetted by water containing moisture binding phosphate compound, as the ice melts.
Claim 10
Independent Claim
122 words
A method of treating shrimp while in the shell to reduce moisture and nutrient loss, comprising: delivering water to a flake ice machine, admixing an amount effective to reduce moisture and nutrient loss of a moisture binding phosphate compound with the water while delivering the water to the flake ice machine, so that such compound will be incorporated into the ice, resulting in colder ice with a greater cooling capacity than plain water ice, and collecting flakes of ice from such machine; mixing such flake ice with shrimp within a storage region aboard a fishing vessel, as such shrimp is caught, said mixed ice and shrimp resulting in shrimp being wetted by water containing moisture binding phosphate compound, as the ice melts.
Claim 11
Dependent Claim
16 words
The method of claim 8, comprising admixing an effective amount of sodium tripolyphosphate with the water.
Claim 12
Dependent Claim
27 words
The method of claim 9, comprising admixing sodium tripolyphosphate with the water in an amount resulting in the ice containing about 1.0-2.0% of sodium tripolyphosphate, by weight.
Claim 13
Dependent Claim
19 words
The method of claim 8, further comprising conveying the iced shrimp from ice storage without washing to a cooker.
Claim 14
Independent Claim
92 words
A method of treating shrimp to reduce the amount of moisture and nutrient loss from the shrimp during storage aboard a fishing vessel and during processing, comprising: storing the shrimp aboard the vessel in ice particles which contains an amount effective to reduce moisture and nutrient loss of a moisture binding phosphate compound, so that as said ice melts to cool the shrimp the meat will be wetted by water containing the moisture binding phosphate compound; and conveying the iced shrimp without washing from ice storage aboard the fishing vessel to cooking.
Claim 15
Independent Claim

Dependent Claim
15 words
The method of claim 12, comprising using ice containing an effective amount of sodium tripolyphosphate.
Claim 18
Dependent Claim
16 words
The method of claim 12, comprising using flake ice containing an effective amount of sodium tripolyphosphate.
Claim 19
Dependent Claim
