Abstract

ABSTRACT OF THE DISCLOSURE

The specification describes an edible shrimp product, and a process for making the same. The shrimp product resembles whole shrimp in appearance, taste and texture and comprises a coherent, shaped agglomerate of shrimp flakes containing a small amount of sodium tripolyphosphate and is substantially free of any added binder or filler.

Description

~8~ 9 i , Background of Invention ~ his invention relates to a commer~ial product resembling large, whole peeled and decapitated shrimp and a process for its ¦Ipreparation. In particular, it relates to a breaded or boiled ;ishrimp product having an appearance, taste, texture and mouthfeel closely resembling that of breaded or boiled.whole shrimp.
Shrimp is such a perishable product that it can not be Ihandled in large quantities commercially without being processed ! to some extent. However, various processes that have hereto beèn !
¦lused have changed the flavor and texture. Processes that have I hereto been used have included freezing, after first dipping in a ¦
¦Isolution of polyphosphate to minimize the loss of moisture upon jthawing of the frozen shrimp. Another described shrimp process ¦involves chopping and dicing. Shrimp have also been freeze-dried land re-hydrated. Also, shrimp have been ground and then reformed ~with a binder or filler.
One object of the present invention is to provide a new ~edible shrimp product made from small shrimp in the shape of a jlarge shrimp having an appearance, taste, texture and mouthfeel resembling that of whole, fresh shrimpO A further object of this ¦
¦invention is to provide such a shrimp product which is ~ree of any added binder or filler.

Summary of Invention The invention comprises generally a new edible shrimp ¦ product which i9 a coherent agglomerate of flaked shr;mp, free , 1, of any binder or filler. One process for preparing this product includes the steps of beginning with a batch of frozen, peeled, l j deveined and decapitated small shrimp, as, for example, species ,, jTiti, having a count of 90 to 200 or more to the pound. The ¦batch is then thawed~and drained and steeped in an aqueous solution containing sodium tripolyphosphate, monosodiumglutamate , and concentrated lemon juice. The shrimp ls then fed into a high-speed-flaking-mach^ine, as for example, Urschel Comitrol, ,~odel 3600. The batch is then mixed, as for example, in a , ~Hobart dough mixer, and transferred to an extruder as, for lexample, the Autoprod Extruder Shape Depositor. The extruded ¦shrimp shapes are then either deposited onto a double dip batter/
breader assembly line, partially fried and then quick frozen or ¦ ;~oiled and then quick frozen.
.` ¦ The resulting products are breaded o r bo i 1 e d shrimp shaped products consistent in size and quality comprising a coherent agglomerate of the flaked shrimp free of added binder or filler. When the breaded product is placed in a deep fat fryer, ¦¦the resultant fried product has an appearance, taste, texture and "mouthfeel`' almost identical to that of large, breaded, fried, whole shrimp. It has none of the inherent mealiness or cereal characteristics of previously described extruded breaded shrimp ;
~ , products with binders or fillers added. The boiled product can ; Il be used in place of whole, boiled shrimp in shrimp cocktail.
The products of this invention can also be made from a starting product that has already been treated with sodium !~ tripolyphosphate. Further, the starting batch can also includ~
~i ¦' smaller pieces of shrimp which are generally sold as "shrimp , pieces."

n~90~ I , ! spoci~ic Examples of Invontion ' Example I-One hundred pounds of frozen, peeled and decapitated speaies Titi shrimp having a count of 90 to 200 or more to the I pound are thawed and drained. The batch lS then placed into an aqueous solution made up as follows:
5 lbs. of water 8 oz. concentrated lemon juice 5 oz~ sodium tripolyphosphate li 5 oz. monosodium glutamate I The shrimp batch and solution are paddle blended together i and the shrimp are then flaked; the mixture fed through an !, Urschel Comitrol 3600 high-speed flaker and then transferred I -into a Hobart mixer. ~fter mixing for two minutes, the mixture ¦, is fed into an Autoprod Extruder which forms large shrimp shaped l~ units. The units are then deposited on a double dip batter/
¦~breader assembly line, which feeds into a partial fryer followed iby quicX freezing. The finished product has a count of approxi-mately 16 to 20 to the pound.
Example II:
The starting batch is frozen, peeled and decapitated species ~Titi shrimp having a 90 to 200 count or more to the pound which i has been previously treated witk sodium tripolyphosphate. The batch is thawed and drained and then placed in an aqueous solution comprising the following:
S lbs. water 8 oz. concentrated lemon juice 5 oz. monosodium glutamate This is paddle blended for about one minute. The mixture is flaked, mixed, extruded, coated, partially fried and quick fro~en in a si~ilar manner as in Example I.
' Example III:
The starting material comprises frozen shrimp pieces which have been treated with sodium tripolyphosphate. A 100 lb. batch ~ 4 ~

is tha~ed and drained and tro-ated in a similar manner as in xample II, except that moisture must ~e care~ully controlled ¦iIf the shrimp pieces in the original batch are too wet, they ¦Ishould be less in proper proportion to shrimp which ~are lei~is wet or which have not been treated with sodium tripolyphosphate.
IExample IV:
¦I The process of Example I is ~ollowed except that after the ~jshrimp shaped units have been formed by the extruder, they are !boiled for two minutes and then quick-frozen.
¦ Examples I, II and III result in breaded coherent, shaped j agglomerates of shrLmp flakes free of any binder or filler.
These breaded products, when placed in a deep fat fryer, provide a fried product which has appearance, taste, texture and I " mouthfeel" almost identical to that of large, breaded, fried ¦¦ whole shrimp.
l The product of Example IV is a coherent, shaped agglomerate I of shrimp flakes free of any added binder or filler and resem~ling I large, whole boiled shrimp in appearance, taste and texture.
¦ These boiled products of the present invention have a ¦ p=rtlcular a licat~on ln ~uch products as =hrimp cocktail.
