- In some embodiments, the composition is a pre-cooked egg patty. In some embodiments, the calcium additive comprises calcium chloride, calcium caseinate, calcium carbonate, calcium citrate, calcium phosphates, calcium lactate, calcium gluconate, calcium lactate gluconate, or dehydrated whey. In some embodiments, the calcium additive consists of calcium chloride.
- In another aspect, a comestible is provided including a composition including whole eggs, egg white, egg yolks, or a fraction thereof or a mixture of any two or more thereof; and a calcium additive; wherein: the composition is an egg patty; and the composition exhibits a reduced microwave heating time required to achieve a target temperature, as compared to an egg patty in which the calcium additive is not present, and optionally one or more meat products.

In one embodiment, where the calcium additive is calcium chloride, the calcium chloride is present at about 0.03 wt %, at about 0.05 wt %, or at about 0.1 wt %.
- Where the calcium additive is derived from dehydrated whey, it is the calcium content of the dehydrated whey upon which the effective amount of the calcium additive is determined. For example dehydrated whey typically has from about 22.5 wt % to about 27.5 wt % of calcium. Thus, where the egg patty contains dehydrated whey as the calcium additive, the dehydrated whey is present in the egg patty at from about 0.13 wt % to about 0.64 wt %. However, the egg patty contains from about 0.03 wt % to about 0.15 wt % of added calcium.
- In one aspect, a method is provided for reducing the heating time of an egg patty including adding an effective amount of a calcium additive to the egg patty, wherein the calcium additive reduces the microwave heating time required to achieve a target temperature compared to an egg patty in which the calcium additive is not present. Thus, the calcium additive reduces the microwave heating time of the egg patty without negatively impacting the taste and texture of the egg patty.
- As discussed above, the target temperature may be a maximum temperature of the egg patty. For fully heating an egg patty the maximum temperature of the egg patty is typically greater than about 47° C. For example, the maximum temperature may be about 48° C. This may include where the maximum temperature may be about 51° C., about 54° C., about 57° C., about 60° C., about 63° C., about 66° C., about 69° C., or about 71° C. In some embodiments, the maximum temperature of the egg patty is above 48° C., above 51° C., above 54° C., above 57° C., above 60° C., above 63° C., above 66° C., above 69° C., or above 71° C. In some embodiments, the maximum temperature of the egg patty is at least 71° C.
- Also as noted above, the target temperature may be a minimum temperature of the egg patty. For example, the minimum temperature may that which is sufficient to warm the egg patty for consumption. In some embodiments, the minimum temperature of the egg patty is from about 48° C. to about 71° C., or higher. This may include individual temperatures of about 51° C., about 54° C., about 57° C., about 60° C., about 63° C., about 66° C., about 69° C., or about 71° C. In some embodiments, the minimum temperature of the egg patty is above 48° C., above 51° C., above 54° C., above 57° C., above 60° C., above 63° C., above 66° C., above 69° C., or above 71° C. In some embodiments, the minimum temperature of the egg patty is at least 71° C.
- As further noted above, the target temperature may be the average temperature of the egg patty. In some embodiments, the average temperature of the egg patty is from about 48° C. to about 71° C., or higher. This may include individual temperatures of about 51° C., about 54° C., about 57° C., about 60° C., about 63° C., about 66° C., about 69° C., or about 71° C. In some embodiments, the average temperature of the egg patty is above 48° C., above 51° C., above 54° C., above 57° C., above 60° C., above 63° C., above 66° C., above 69° C., or above 71° C. In some embodiments, the average temperature of the egg patty is from about 48° C. to about 88° C. In some embodiments, the average temperature of the egg patty is from about 66° C. to about 71° C. In some embodiments, the average temperature of the egg patty is at least 71° C.
- The microwave heating time required to achieve the target temperature will vary depending on the desired target temperature and the starting temperature of the egg patty, as well as the dimensions of the egg patty. Heating time will also vary depending on the power and settings of the microwave in use. A suitable heating time can be determined empirically by microwaving egg patties for varying periods of time and measuring the temperatures achieved. Methods for measuring the temperature of egg patties are known in the art, including but not limited to the use of a temperature probe inserted into various regions of the egg patties.
- The microwave heating time required to achieve the target temperature will vary depending on the different components used to make the sandwich. Different bread types heat differently, different meats heat differently.
- The heating time required to achieve a target temperature is from about 60 seconds to about 120 seconds. In some embodiments, the heating time is from about 60 seconds to about 75 seconds. This includes, heating times of about 60, about 65, about 70, about 75, about 80, about 85, about 90, about 95, about 100, about 105, about 110, about 115, or about 120 seconds.
- Calcium additives may include any edible substance containing calcium, the inclusion of which is compatible with the preparation and consumption of an egg patty, without negatively impacting the taste or texture of the egg patty. Calcium additives may include, but are not limited to, calcium chloride, calcium caseinate, calcium carbonate, calcium citrate, calcium phosphates, calcium lactate, calcium gluconate, calcium lactate gluconate, or dehydrated whey. The calcium additive may be a mixture of any two or more such additives. In some embodiments, the calcium additive is calcium chloride. In some embodiment, the calcium additive is anhydrous calcium chloride. In one preferred embodiment, the calcium additive is a dehydrated whey.
- What constitutes an effective amount of a particular calcium additive will depend on the desired target temperature and the characteristics of that substance, including the proportion of the substance that is calcium. For example, an effective amount of a calcium additive having a proportionally higher calcium content may be less in terms of absolute mass than that of a calcium additive having a proportionally lower calcium content.
- The effective amount of a particular calcium additive may be determined empirically by preparing egg patties with varying amounts of the additive, microwaving them for a specified period of time, and measuring their temperatures. Additionally or alternatively, the effective amount may be determined by preparing egg patties with uniform amounts of the calcium additive, microwaving them for varying amounts of time, and measuring their temperatures. Which method is more suitable will depend on the specific objectives of the artisan, such as whether there is a preferred microwaving time or additive amount.
- In some embodiments, an effective amount of a calcium additive is from about 0.02 to about 0.15 wt % of the egg patty. In some embodiments, an effective amount of calcium chloride is about 0.03, 0.05, or 0.15 wt % of the egg patty.
- In one aspect, a composition is provided including whole eggs, egg whites, egg yolks, a fraction thereof or a mixture of any two or more thereof; and a calcium additive, wherein the composition is an egg patty, and the composition exhibits a reduced microwave heating time required to achieve a target temperature, as compared to an egg patty in which the calcium additive is not present. The composition may, optionally, include non-egg ingredients, including but not limited to meats, vegetables, spices, seasonings, diary products (e.g., milk, cream, whey, buttermilk, cheese, ghee, yogurt, clabber, butter, casein, anhydrous milkfat,), oils, flavorings, emulsifiers, or any other ingredient compatible with the preparation and consumption of the egg patty.
- The composition may be prepared from any egg variety, such as those produced by birds. Bird varieties include but are not limited to chicken, duck, turkey, quail, goose, ostrich, gull, pheasant, emu, guineafowl, pelican, pigeon, partridge, or any wild or domesticated poultry.
- The composition may be cooked in the shape of a patty, such as by adding uncooked ingredients to a suitable mold for cooking, or may be formed into the shape of the patty after the ingredients are cooked. Alternatively, the ingredients may be partially cooked and then shaped in to a patty for the completion of cooking Egg products used in the composition may be cooked in any manner compatible with the preparation of eggs, including but not limited to boiling, frying, poaching, or baking Egg products used in the composition may be fresh, or may be preserved by any method compatible with the preservation of eggs, including but not limited to freezing, salting, pickling, and dehydration.
- Calcium additives suitable for use in the composition include but are not limited to calcium chloride, calcium caseinate, calcium carbonate, calcium citrate, calcium phosphates, calcium lactate, calcium gluconate, calcium lactate gluconate, or dehydrated whey. In some embodiments of the composition, the calcium additive is calcium chloride. In some embodiments of the composition, the calcium chloride is anhydrous. In some embodiments of the composition, the calcium additive comprises dehydrated whey. In some embodiments, the calcium additive is present from about 0.02 to about 0.15 wt %. In some embodiments, the calcium additive is present at about 0.1 wt %.
- Bread products suitable for use with the composition include, but are not limited to, baked goods such as breads, crackers, biscuits, croissants, and the like. Meat products suitable for use with the composition include but are not limited to beef, poultry, pork, or fish products, whether whole or processed. Thus, the egg patty may be assembled into another type comestible. For example, the comestible may be a sandwich that includes a bread product, and optionally one or more meat products, and any of the egg patties as described above.
- The present invention, thus generally described, will be understood more readily by reference to the following examples, which are provided by way of illustration and are not intended to be limiting of the present invention.
- The methods and compositions disclosed herein are further illustrated by the following examples, which should not be construed as limiting in any way.
- This example demonstrates that egg patties including a calcium additive exhibit reduced microwave heating times to achieve a target temperature compared to egg patties lacking the calcium additive.
- Egg patties containing 0 (control), 0.1, 0.2, and 0.4 wt % CaCl2 were assembled as sandwiches with sausage, cheese, and a croissant and placed at −18° C. until frozen. The frozen sandwiches were wrapped in a paper towel and microwaved with no intervening thaw time. The sandwiches were heated in a 1100 Watt microwave on setting high for 65, 70, or 75 seconds. Sandwiches were held in the microwave for 90 seconds after following heating, to allow component temperatures to equilibrate. The bread top was removed from the sandwich, and the egg patty temperature was measured in the center and at four additional locations across the diameter of the patty.
- In general, egg patties containing CaCl2 displayed higher minimum, maximum, and average temperatures for each heating time than egg patties containing no CaCl2 (
FIGS. 1-3 ). In addition, egg patties containing CaCl2 displayed fewer cold spots, which are defined as locations on the egg patty that are cold to the touch (less than approximately 21° C.) (FIG. 4 ). - These results demonstrate that the inclusion of a calcium additive in an egg patty reduces the heating time required to achieve a target temperature. This shows that the methods and compositions described herein are useful for reducing the heating time of an egg patty, such as would permit single-step microwave heating of a frozen egg patty sandwich without over-heating the non-egg patty components.
