Abstract

Abstract Deviled eggs are prepared by an improved method, starting with a blended mixture of liquid egg whites. The mixture is evacuated to remove air and other gases, then dispensed into molds shaped like half an egg and of similar size. A second mold is positioned centrally in the first mold to make a cavity in the egg white similar in shape and size to half an egg yolk. The egg white is cooked in steam at atmospheric pressure, then cooled, and removed from the mold. Into the resulting cooked egg white shells is dispensed a mixture of cooked egg yolk and seasonings, yielding the desired deviled egg product.

Description

The presen-t invention relates to -the production of deviled eggs, and more particularly to the production of cooked egg white halves from blended egg whites.
The conventional method for ma~ing deviled eggs is labor-intensive, involving boiling the eggs in the sheLl, remov-ing the shell, splitting the eggs in half, separating -the yol]cs from the whi-tes, blending the yolks with seasonings, and dis-pensing the seasoned yolks back into the yolk cavity of the whites. Because of the inordinate amount of labor required, deviled eggs tend to be relatively expensive and indeed are beyond the reach of certain food purveyors, e.g., school cafeterias, where they might otherwise be consumed in large quantities.
It is accordingly of interest to minimize the labor cost involved in producing deviled eggs. This is achieved in the present invention by separate bulk-processing of egg whites and egg yolks according to techniques described hereinafter.
The invention provides in the production of deviled eggs, the improvement which comprises pooling and blending liquid egg whites, exposing the liquid egg whites to vacuum to remove dissolved and entrained gases therefrom, dispensing the de-gassed liquid egg whites into molds of the shape and size of half an egg with a centrally disposed, removable insert which forms a hemispherical cavity the size of half a yolk in the egg white pool in each mold, and cooking the liquid egg white in the molds, whereby cooked egg whi-te halves are obtained suitable for filling with cooked, seasoned egg yolk to produce deviled eggs.
The invention makes it possible to prepare deviled eggs in a simpler and more economical manner than available heretofore, and reduces the labor cost component in the pre-paration of devi:Led eggs. Directly from blended liquid egg 5~

whites, a product is prepared having -the form and other characteris-tics oE hard-cooked egg white halves. Hard-cooked egg white halves prepared in this way can be -Erozen and thawed without loss in quality.

-2a-~ ~ .

55i~7 Other objects of the invention and its advantages over the prior art will be apparen-t from the following description.
In one embodiment of the invention, deviled eggs are prepared according to the following procedure: Raw eggs are broken and the yolks and whites are separated and separately pooled. The egg whites are blended under vacuum until homogeneous and until dissolved and entrained air and other gases have been removed therefrom. The de-aerated egg whites are dispensed into molds of the shape and size of half an egg, with a centrally disposed, removable insert which forms a hemispherical cavity the size of half a yolk in the egg white pool in each mold. The egg whites are cooked, e.g., with steam. The central insert is then removed, and the cooked egg white halves are unloaded, or alternatively, they are filled ln situ.
The filling for the egg white halves is prepared by cooking the pooled egg yolks until solid and dry, and blending the cooked yolks with appropriate seasonings. The ~0 yolk mix is dispensed into the cooked egg white halves to form the completed deviled eggs.
The product thus obtained can be stored for a limited time under refrigeration. For longer-term storage and shipping, it can be subjected to quick freeæing in a known manner -- for examplet in spaced trays in a freezer with forced-draft circulation of chilled air. Quick freezing is preferred in order to minimize any tendency of the product to exude water on thawing and to prevent an unsatisfactory appearance. Further protection for the froæen product can be achieved if desired by incorporating a water-binding material into the pooled egg whites before they are vacuum-~reated and cooked, as described in Hawley U.S. Patent 3,510,315.
The water-binding materials include a varie~y of starches, edible gums~ and food--grade water-soluble cellulose derivatives which are capable, by virtue oE their polymeric structure and hydrophilic nature, of absorbing and retaining the water in the liquid egg whites through the cycle of cooking~ freeæing~ and thawing. Particularly useful are carbohydrates such as corn, tapîoca, rice, and potato starches; edible gums such as gum arabic, gum acacia, gum tragacanth, karaza gum, ghatti gum, locust bean gum~ guar gum, and carrageenan, as well as ayar and algin; and water-soluble, food-grade cellulose derivatives such as methylcellulose, methylethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, methylhydroxyethylcelluose, ethylhydroxyethylcellulose, methylhydroxypropyl cellulose, sodium carboxymethylcellulose, and sodium carboxymethylhydroxyethylcellulose; and the like. The water-binding materials can be added to the liquid egg white in an amount up to about 10% by weight based on the weight of the liquid egg whi~e, preferably between about 2% and about 4% by weight for starches and between about 0.25~ and about 1% by weight for gums and cellulose derivatives.
The use of vacuum treatment in processing blended egg materials has been carried out heretofore for a variety of reasons. ~eynolds U.S. Patent 1,842,733, in mixing egg white and/or yolk with a solid such as salt or sugar, carries out the operation in vacuo to avoid incorporation of oxygen into the mixture (which would cause deterioration of the product) and t:o avoid formation of an objectionable layer of :~9~5~7 foam at the top of the mixture. Heuser U.S. Patent 1,g89,359 mixes whole egg with sugar and a salt, then applies high vacuum to remove air~ thereby obtaining a clear liquid for further processing~ Jones U.S. Patent 3,113,872 homogenizes egg, pasteuri2es, then heats briefly under vacuum to remove ob~ectionable odors and flavors. Ballas U.S~ Patent 3,404,008 also pasteurizes egg whites or other egg materials, but applies vacuum to remove entrapped air before heating to pasteuriæing temperature, thereby avoiding localized overheating and coagulation~ In the present invention, the removal of air helps in preventing the formation of air bubblesl air holes, and a spongy texture in the cooked egg white, and thereby substantially improves the quality of the product.
The degree of vacuum employed is not critical, since the goal is only to avoid any separation of gas bubbles in subsequent processing. Ordinarily, an absolute pressure of 50 to 100 mm Hg in the treating vessel is sufficient, with gentle stirring over a period of 5 to 10 minutes, to adequately remove the dissolved and entrained gases. The higher the vacuum, of course, and the longer the treatment time, the more fully will the gases be removed, but total removal is unnecessary. The vacuum treatment can be carried out either during the blending operation or as a subsequent step as desired.
The present invention is described in the attached drawings, as follows:
Fig. 1 is a process flow sheet illustrating a detailed form of the invention which begins with separated egg whites and egg yolks and ends with frozen deviled eggs;

Fig. 2 is a simple apparatus for cooking egg whites to form cooked egg white halves having centrally located cavities of the size and shape of half a yolk;
~ ig. 3 illustrates a filler station for dispensing a mixture of cooked yolk and seasonings into the cookecl egg whi~e halves; and Fig. 4 is a cross-sectional view of the deviled egg product of the invention.
The process of Pig. 1 begins with separated egg whites 10 and egg yolks 24t obtained in a known manner from eggs of breaker quality.
Egg whites 10 and a water-binding carbohydrate 12 such as modified tapioca starch are thoroughly blended 14 in a vessel to which vaccum 16 is applied to remove dissolved and entrained air and other gases~ The blended and de-gassed mixture is dispensed 18 into molds, for example as illustrated in Fig. 2~ and cooked 20 in steam 21 until completely solidified. The resulting egg white halves 22, having centrally located cavities of the size and shape of half a yolk, are removed from the molds.
In a separate operation, egg yolks 24 are thoroughly blended 26, cooked 28 until solid and dry, and blended 30 with seasonings 32 such as salt, pepper, mustard~
paprika, and mayonnaise or salad dressing to yield deviled egg filling mixture 34. The latter is dispensed 36 (see Fig.
3) into egg-white halves 22, yielding the desired deviled egg product 38 (see Fig. 4). The product can be frozen 40 if desired, and when wrapped and stored in water-impervious plastic~ retains its quality for a long time. It is restored essentially to its original form upon thawing.

Fig. 2 is a drawing in cross section of a mold and cooking assembly for use in the present invention. Into a cavity 210 in conveyor belt 212 is placed mold 214, suitably made of thin-gauge stainless steel. The mold, having the six\ze and shape of half an egg, is retained by lip 216 upon edge 218 of every cavity 210. Centrally positioned within mold 214 is a hemispherical insert 220, which forms the lower end of cylindrical retainer 222. Means (indicated symbolically at 224) are provided for introducing and retracting insert 220.
With insert 220 in place, liquid egg white 226 is dispensed into mold 214 to substantially fill the mold, which is then moved upon conveyor belt 212 through a steam bath (surrounding the entire assembly at such a rate as to allow the egg white to become completely solidified before emerging from the bath. When cooking is complete, insert 220 is retacted and the cooked egg white (22 in Fig. 1) is removed from the mold.
The cooked egg white halves are then conveyed to filler station 310 (Fig. 3), where deviled egg fillin mixture 312 (34 in Fig. 1) is dispensed into them (36 in Fig. 1), yielding the final deviled egg product 314 (38 in Fig. 1) shown in Fig. 4.
The product, Fig. 4, is a typical develied egg, having the seasoned yolk consumption 410 filled into the cavity of the cooked egg white half 412, differing only in that the yolk compostion is always centrally placed in the product of the presr\ent invention.
While the invention has been described with reference to certain specific embodiments thereof, it is to be understood that numerous modifications may be made without departing from the spirit of the invention. Such laced 5S~7 modifications are therefore to be understood as lying within the scope of the invention.
