BACKGROUND

[0002] Frozen foods and associated packaging allow consumers and food preparers to store foods in a dormant state for later preparation, such as in a microwave, on a stove, or with another heat source. The frozen foods can he prepared according to a particular standard by a producer and shipped to a food preparer to provide convenient preparation options for subsequent heating or reheating of the food.

SUMMARY

[0003] This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary _' is not intended to identify key and/or essential features of the claimed subject mater. Also, this Summary- ⁷ is not intended to limit the scope of the claimed subject matter in any manner.

[0004] Aspects of the disclosure pertain to gluten-free vegetable hash-based flexible food products that maintain flexibility and malleability following a freeze/thaw cycle and prior to a cooking process such as frying, baking, microwaving, or the like. The food product can include a combination of gluten-free ingredients such as gums, starches, and flours to support post-thaw flexibility and malleability after a designated thaw period while maintaining a thin shaped profile. The food product can be folded into a desired shape following the thaw period and cooked to maintain a non-planar shape and avoid leakage of fluids from moisture- containing foodstuffs held by the food product. The moisture-containing foodstuffs can include, for example, egg-based products (e.g., scrambled eggs), proteins (e.g., meats), vegetables (e.g., peppers, onions, etc.), sauces, condiments, and the like. [0005] In an aspect, a method for producing a food product having malleability and flexibility following a freeze/thaw cycle includes mixing vegetable pieces, starch, flour, fat, gum, and water to form a flexible and malleable gluten-free dough, flattening the dough into a sheet to provide a flatened dough, and freezing the flatened dough to provide a frozen food product that can withstand a freeze/thaw cycle for subsequent shaping and cooking into a desired shape.

DETAILED DESCRIPTION

[0019] Aspects of the disclosure are described more fully hereinafter with reference to any accompanying drawings, which form a part hereof, and which show, by way of illustration, example features. The features can, however, be embodied in many different forms and should not be construed as limited to the combinations set forth herein; rather, these combinations are provided so that this disclosure will be thorough and complete, and will fully convey the scope. Among other things, the features of the disclosure can be embodied as formulations, food products, and processes for producing formulations and food products. The following detailed description is, therefore, not to be taken in a limiting sense.

[0020] Frozen food products are often used in the food service industry to provide convenient storage of pre-prepared or pre-cooked foods to he subsequently thawed, heated, reheated, or cooked and served to customers. A food service company can receive frozen foods products from a frozen food distributor that prepares the food products according to the particular standards desired by the food sendee company for convenient distribution across multiple distribution channels, restaurants, stores, and the like, while providing a consistently prepared food product at each location.

[0021J Howe ver, freezing and thawing processes can negatively affect food products.

For example, the freezing process can cause certain foods to dry out during storage or transport due to moisture loss (e.g., from ice crystal formation) and can cause foods to become brittle or unmalleable upon thawing. As another example, if the food product is not thawed for a proper duration, the food product may still have ice crystals that can lead to an improperly cooked food or otherwise provide a negative consumer eating experience (e.g., if the thaw duration is too short) or the food product may lose additional moisture during the thaw process causing tiie food to become dry, brittle, or unmalleable (e.g., if the thaw duration is too long). Further, frozen food products may incorporate gluten-containing ingredients, however gluten can negatively affect consumers, such as those with gluten sensitivity, celiac disease, or other health conditions.

[0022] An exemplary food product includes vegetable pieces, starch, flour, fats, gums, and water formed into a flattened shape for subsequent freezing, thawing, and cooking.

Example Frozen Product Production

[0049] Referring to FIGS. 1 -2, a process 100 for producing an example food product Is shown. The process 100 begins with an optional step of rehydrating potato shreds in operation 102. For example, when the food product includes dehydrated potato shreds as the vegetable pieces, rehydration of the potato shreds can enhance mixing of the potato shreds in subsequent steps of dough formation, in an aspect, potato shreds in a weight percentage of total content of from about 9.7% to about 18.1% and hot water (e.g., from about 130°F to about 170°F) in a weight percentage of total content from about 29.5% to about 54.7% are added to a mixer. The mixer can be operated to m ix for a time period and to rest for a time period according to a number of cycles and according to a variety of mixing speeds. In an aspect, the mixer can mix the hot water and the dehydrated potato shreds for a first time period (e.g., from about 20 to about 40 seconds) at a low speed and then permit the mixture to rest for a second time (e.g., from about 2 to about 4 minutes) for a single cycle and then repeat the cycle multiple times.

[0050] The process 100 includes operation 104 where the fats are added to the rehydrated potato shreds. In an aspect, shortening in a weight percentage of total content from about 1 .6%) to about 3.0%) and a liquid fat in a weight percentage of total content from about 1.5% to about 2.9'% are added to the mixer and mixed with the rehydrated potato shreds. In an aspect, the fats are mixed with the rehydrated potato shreds for a duration from about 1 to about 3 minutes at a low speed. The process 100 also includes operation 106 where the remainder of the food product ingredients are introduced. For example, the remaining dry ingredients of the food product and cold water can be introduced to the mixture to mix with the fats and rehydrated potato shreds to produce a dough. The mixing process of operation 106 can include multiple mixing steps. For example, operation 106 can include a first mixing step where the remaining dry ingredients of the food product are first introduced to the mixer to mix with the fats and rehydrated potato shreds for a first duration (e.g., from about 0.5 minutes to about 1 .5 minutes). Hie operation 106 can then include a second mixing step where a first portion (e.g, about one-half) of the cold water is added to the mixer to mix for a second duration (e.g, from about 0.5 minutes to about 1.5 minutes) followed by a third mixing step where the remainder of the cold w'ater is added to the mixer to mix for a third duration (e.g, from about 0.5 minutes to about 1.5 minutes). The mixed dough can then be permitted to rest prior to any additional mixing and resting steps.

[0051] The process 100 also includes operation 108 where the dough is flattened into sheets to prepare the dough for freezing. In one aspect, sheeting equipment can flaten the dough into sheets having a thickness from about 0.12 inches to about 0.20 inches. For example, tiie sheeting equipment can flatten the dough into sheets having a thickness from about 0.15 inches to about 0.17 inches. Following the sheeting process, the process can proceed to an optional shaping process in operation 110. For example, the sheeted dough can be cut into shapes. In one aspect, the sheeted dough is cut into circles having a diameter from about 3 inches to about 7 inches. Hie shaped dough can facilitate shaped cooked food products of the present disclosure to create an interior volume into which additional foodstuffs can be placed and consumed along with the shaped cooked food products. For example, the shaped dough can be formed into non-planax shapes (e.g, through usage of a cradle or other forming device during a frying or cooking operation) where an interior of the non-planar shape can hold the additional foodstuffs. The additional foodstuffs can include, but are not limited to, egg-based products (e.g, scrambled eggs), proteins (e.g, meats), vegetables (e.g, peppers, onions, etc.), sauces, condiments, and the like.

[0052] The process 100 can also include an optional packaging process in operation

112. For example, the sheeted dough (and optionally shaped dough) can be individually or bulk packaged into freezer bags or containers. The food product maintains flexibility and malleability during operations 108, 110, and 112 prior to freezing. The process 100 then proceeds to operation 114, where the dough products are chilled to a substantially frozen state. Alternatively or additionally, portions of the dough products can be frozen, cooled, or partially frozen prior to introduction to storage bags. As used herein, the term “frozen state” refers to tiie state of foodstuffs having been subjected to chilled temperatures tor a duration sufficient to presen/e the foodstuff from spoilage by freezing water contained therein and can include, for example, foodstuffs having a temperature below about 0°F. In one aspect, the freezing process subjects the food products to a temperature of about -9°F for a duration of about 24 hours. Following freezing, the food product can be stored to transported (e.g., to a food service provider or distributor),

[0053] Referring to FIG. 2, the process 100 includes steps to prepare the dough for consumption following the freezing process in operation 114. For example, the process 100 can proceed to operation 116 where the frozen food product is permitted to thaw. In one aspect, the frozen food product is thawed under refrigerated conditions (e.g., about 48°F). The duration of thawing was de termined to be an important factor in the ability of the food product to maintain flexibility and malleability prior to cooking. Thawing durations of about 24 hours and higher promoted the development of a dried appearance in the food product and an increase in breakage of the dough during subsequent shaping steps (e.g., operation 118 described herein). Thawing durations of less than about 10 hours did not allow' for a full melt of ice crystals present in the food product following freezing in operation 114.

[0054] Following thawing, the process 100 also includes operations 118 and 120, where the thawed dough is shaped and cooked, respectively, in one aspect, the thawed dough is shaped by placing the thawed dough into a cradle formed by a frying basket and then fried in hot oil to cook the dough into the shape formed in the cradle. For example, the thawed dough can form a non-planar shape, including but not limited to, a shell shape (e.g., a characteristic taco shell shape), in the cradle of a frying basket and cooked at a temperature of about 350°F for about 1.5 minutes. An example of the cooked food product is shown in FIG. 3, where the food product presents a characteristic taco shell shape while providing a hash brown texture and having visible potato shreds m the shell. Tire process 100 can also include introduction of additional foodstuffs in operation 122 to provide a consumer product for consumption. For example, the additional foodstuffs can include, for example, egg-based products (e.g., scrambled eggs), proteins (e.g., meats), vegetables (e.g., peppers, onions, etc.), sauces, condiments, and the like, placed into an interior of the food product formed during the shaping and cooking process (e.g., into the taco-shell shape).

Example Development Research

[0055] Incorporation of different types of starches and flours was evaluated at multiple stages of the development process of the food products described herein. In an example study, food products including the following ingredients were evaluated: pregelatinized corn starch from waxy maize (e.g., to develop a crispy texture), pregelatinized unmodified potato starch (e.g., to improve reliability and prevent cracking), pregelatinized potato starch from waxy potato (e.g., to help to hind the ingredients), and multifunctional rice flour (e.g., to provide stability during cold storage). All ingredients were tested in different concentrations to achieve tiie desired conditions in the final fried product. For example, FIG. 4A shows evaluation of initial concentrations of ingredients and FIG. 4B shows evaluation of example final fonnulations.

[0056] A s tudy on the effect of pre-cooking the dough prior to freezing was conduc ted to review the effect of heat on the degradation of starch and increase tire resistance of the dough during the placement in the frying basket. A countertop gas griddle was used at 350°F and the food product was tested for 1 and 2 min (half time on each side) and compared with samples without pre-cooking. Although the pre-cooked products showed better resistance to breakage, it was not possible to fold it to place the pre-cooked products in the frying basket without subsequent fracture.

[0057] A study on the effect of inclusion of gums into the food product were conducted.

It was noted that after the freezing and thawing processes, many test formulations lacked moisture that was causing cracking on the surface and eventually promoting breaking during the placement of the food product into the fryer basket and after frying (examples shown in FIGS. 5A, 5B, and 5C). Gums w'ere then introduced into test formulations to determine the effects on elasticity after thawing. Results after the incorporation of die gum were positive and the test products were able to keep a circular shape without breaking before and after frying (examples as shown in FIGS. 6A and 6B). Furthermore, the test products presented a more hydrated surface after thawing. However, not ail gums presented sheetability of the test formulations. In one test, guar gum has a poor binding effect between the ingredients and w¾s not able to form a sheet (example shown in FIG. 7A), whereas other gums, such as the example formulation made with konjac gum shown in FIG. 7B, improved the malleability of the dough during sheeting in the sheeting machine.

[0058] A study on the effects of introduction of additional foodstuffs to a cooked food product described herein was performed. Empty cooked shells having a characteristic taco shell shape were left under a heat lamp for durations of 15 minutes, 30 minutes, and 60 minutes to evaluate changes in texture. No visible changes were detected , Afterward, new cooked food products were filled with fresh and warm scrambled eggs and ham and cold hot sauce was added on top of the added foods. The food product was evaluated under a heat lamp and without a heat lamp. After 30 minutes, 60 minutes, and 120 minutes, the shell presented the same texture, and there was no migration from moisture released by the additional foodstuffs. No leaking was observed in any of the tested conditions.
