    DETAILED DESCRIPTION

    [0017] The present disclosure relates to frozen dough products and method of making the same. The present invention further relates to ready-to-cook frozen dough products and method of making the ready-to-cook frozen dough products. In particular, the present invention relates to method to produce bread, steamed bread, fried bread and microwaved bread frozen dough products that are raw and that are capable of being cooked directly from frozen state to produce a finished product for consumption. According to embodiments of present invention, the method of preparation comprises a step of subjecting a frozen dough product to at least one freeze-thaw cycling prior to re-freeze the dough and storing the dough products at frozen conditions.

    [0018] The term freeze-thaw cycle or freeze-thaw treatment is used here to refer to a treatment to the dough which is defined as having the dough undergo at least one ice-to-water phase change in dough starting from a frozen state, thawing and then returning to completely frozen state. The term freeze-thaw cycling is used here to refer to the process of conducting a freeze-thaw cycle by changing the dough temperature. According to embodiments of the present invention, the dough temperature can be changed by bringing the dough from frozen state (40 F. to 30 F.) to a thawed state in a cooler (34 F. to 40 F.), at cold manufacture conditions (from 50 F. to 65 F.), or at countertop in room temperature (around 65 F. to 80 F.), or at elevated temperature in a fermentation or a proof room or cabin (e.g. 80 F. to 110 F.) for a time ranged from a few minutes to several hours until the size of the product is about double. It is generally understandable that at a lower temperature, a longer time is required and vice versa. In some embodiments of present invention, microwave energy is used to assist in causing a temperature change more efficiently and to shorten the time of the freeze-thaw cycling. Dough in a frozen state could be thawed using microwave energy assistance in the low energy defrosting or thawing model.

    [0019] The term negative control is used herein to refer to samples that were prepared without using the present invention but cooked directly from frozen state as what is done for the present invention.

    [0020] The term positive control is used herein to refer to samples that were prepared using a full fermentation and proofing prior to cooking.

    [0021] The term about is used here to indicate variations in measurement as expected by persons skilled in art and is understood to cover a typical margin of error such as 5% of the stated value.

    Frozen raw food materials normally require some treatments before the materials can be cooked for consumption. Raw dough can be warmed up and fermented or proofed before baking. When a raw dough is thawed, fermented and proofed before baking, a higher quality of a finished product will normally result, compared to a finished product that is baked directly from frozen status. However, additional preparation steps are often time consuming and take away the conveniences that consumers will enjoy if the frozen food were cooked right from the freezer without having to thawing, resting, fermenting or proofing. For example, a resting time of 3-4 hours is normally required for a frozen dough ball to double in volume and be ready to bake. According to embodiments of the present invention, dough made using the method of the present invention can be cooked directly from the frozen state, and food articles prepared using the present invention have a product quality comparable to known prior arts.

    [0022] One option to shorten or eliminate the preparation time prior to cooking frozen food items is to complete these steps before freezing. For example, a dough can be proofed before freezing, thereby, eliminating the hour long proofing step at the point of cooking. The challenge is that a proofed dough is more vulnerable to freezing damage than a dough without proofing. In addition, the gas holding ability of a dough is limited and typically a dough will lose gas during the frozen storage, giving rise to a lower quality product at final cooking. Therefore, pre-proofing the raw dough, freezing, and baking directly from frozen state usually compromises product quality and their applications are limited to certain products that have low specific volumes after cooking.

    [0023] Another option is to use chemical leaveners, or a combination of chemical leaveners and yeast. Dough is mixed like yeast leavening products, but chemical leaveners are added to the dough. Dough could be preproofed or not preproofed and frozen after makeup. Dough product is cooked directly from the freezer. Chemicals leaven the dough during baking due to carbon dioxide produced by the reaction of sodium bicarbonate with a leavening acid, such as sodium acid pyrophosphate, sodium aluminum phosphate, mono calcium phosphate, glucono delta lactone, cream of tartar (potassium bitartrate), or citric acid. Products utilizing chemical leaveners will produce a texture of biscuit type. While yeast leavened products have larger and well-defined cell openings, chemically leavened breads possess grainy and dense textures with small air cell openings.

    [0024] Depending on product types, a selected method could be useful for one type but not another. No all preproofed methods or chemical leavening methods can be applied to all types of products. Pre-proofing is typically not applicable to bread type products, such as loaves and buns. These products have a soft and tender texture and preproofing will result in issues in product handling. More importantly, these products typically have a very high specific volume (e.g. 5-6 mL/g), making it impossible to preproof the dough and keep the dough in a frozen state without altering the size and shape. Dough is typically damaged during frozen storage and collapsed during cooking. Similar challenges exist for dough products that are cooked directly from frozen regardless of the cooking methods used including baking, steaming, frying or microwaving.

    [0025] In order to produce dough products that can be cooked directly from a frozen state, modifications are required for the dough. The dough needs to possess a rheological property that can expand during cooking without shrinking back. The dough also requires sufficient reservations in leavening actions so that enough gases can be produced to leaven the dough and increase the volume. The dough also needs to be in a geometrical property suitable for dimensional volume changes. For example, a flatbread can expect a two-dimensional volume changes, while a bun can expect three-dimensional volume changes during cooking. Small dough pieces will have a higher heat transfer efficiency compared to larger dough pieces, and products will expand and perform differently based on their sizes and shapes. According to embodiments of the present invention, the cooking performance of frozen dough products are enhanced when freeze-thaw cycling is used as a treatment to dough.

    [0026] When a dough intended to be used as a ready-to-cook frozen dough is prepared using the traditional pre-proofing method or the combination of a yeast and chemical leavener agents, the dough is not performing to an acceptable bread quality. The common issues are a collapsed bread, wrinkles on the skin, loss of an attractive golden-brown color, or loss of a shiny smooth skin for some products. Instead, the skin is dull, grey and grainy like, and the texture is dense and gummy, with a low volume. The reasons are due to the damage effects that the freezing has on a preproofed product. The preproofed dough has an air cell structure that is susceptible to physical damage, and the dough, after being proofed, typically has poor gas-holding ability. In some cases, cooking a pre-proofed frozen dough is similar to cooking an over-proofed dough, which usually collapses during cooking. A dull, grey and grainy skin is observed when chemical leaveners are used and no proofing or a very small amount of proofing is used. The issue in the skin is likely due to the lack of leavening actions, especially the lack of leavening action from yeast.

    [0027] It was discovered that when a ready-to-cook frozen dough undergoes a freeze-thaw cycle, the dough performs to an acceptable quality similar or close to the quality of a control product that is prepared by thawing, fermenting and proofing prior to baking or steaming Surprisingly, it was discovered that the collapsed phenomenon of a proofed dough during cooking can be prevented by instead of proofing, adding to the processed dough a freeze-thaw step with at least one freeze-thaw cycling. After adding a freeze-thaw cycling step to the dough, the frozen dough is greatly enhanced in cooking performance and the cooked product has a quality meeting the texture, volume and visual appearance of a finished product using various cooking mechanism such as baking, steaming, frying, and microwaving.

    [0028] According to the embodiment of the present invention, common bakery ingredients are used in frozen dough preparation. A hard wheat flour is suitable for baked bread production and both hard and soft wheat flour are used for steamed bread production. However, a weaker hard wheat flour and a stronger soft wheat flour are more suitable for steamed bread production. All purpose flour is suitable for both baked and steamed bread making. White refined wheat flour and whole grain wheat flour can be used to prepare product of present invention. Grains other than wheat can also be used. Examples of common grains include wheat, oat, barley, rye, rice, corn, quinoa, millet, sorghum, triticale, amaranth, and buckwheat. Both gluten flour, including wheat, barley, rye and gluten free flour can be used. Examples of common gluten free flour are oat, rice, corn, quinoa, millet, sorghum, triticale, amaranth, and buckwheat. Ancient grains can also be used. Example of ancient grains include einkorn, kamut, spelt, black barley, red and black rice, blue corn; sorghum, teff, millet, quinoa, amaranth; buckwheat, or wild rice.

    [0029] Various yeasts can be used for preparation of the frozen dough products using embodiments of present inventions. Commonly used yeasts include cream yeast (moisture content about 82%), compressed yeast (moisture content about 35%), frozen yeast (moisture content about 20%), active dry yeast (moisture content about 7%), instant yeast (moisture about 5%). Although various yeasts differ in moisture content and the granular form, all yeasts can be used in preparation of the frozen dough products.

    [0030] Various chemical leaveners are also available for use in the preparation of the frozen dough products. Sodium bicarbonate is the most common leavening base available from general stores. When a low sodium product is desirable, potassium bicarbonate can be used in place of sodium bicarbonate. One or more leavening acids are used together with the sodium or potassium bicarbonate. Common leavening acids include sodium acid pyrophosphate, sodium aluminum phosphate, mono calcium phosphate, glucono delta lactone, cream of tartar (potassium bitartrate), citric acid etc. Encapsulated chemical leaveners can also be used in the preparation of frozen dough. For example, encapsulated forms of sodium bicarbonate, sodium acid pyrophosphate, sodium aluminum phosphate, mono calcium phosphate, glucono delta lactone, and citric acid are available from major food ingredient suppliers and can be used in the preparation of the frozen dough.

    [0031] According to embodiments of the present invention, the dough is mixed using flour, water, yeast and optionally salt, sugar and other additives. When other ingredients are used, flour and dry ingredients are blended for 1 min at a dough mixer, e.g. a Kitchen Aid, or a Hobart mixer. Yeast and water are then added and the dough is mixed for 1-2 min in low speed (typically about 30-40 rpm) to hydrate the flour. The dough is then mixed at high speed (typically 80-120 rpm) for 4-10 min to develop the gluten structure. After mixing, the dough will have a cohesive, resilience and viscoelastic rheology, meaning it is flexible but not sticky, is deformable when forced, not plastic, and has enough elastic properties to support dough structure and enough viscous properties to trap gas and enhance gas holding ability. After mixing, the dough can proceed directly to make up without resting. Optionally, dough can rest for a short period of time. For example, dough can rest for 10-30 min before make up. During make up, dough is shaped, sheeted or compressed to form desired sizes, forms and ornamental designs, or certain configurations. Make up for the dough can take several sizes. For example, dough for mini bread can range from 100-200 g. Dough for steamed bread loaves and buns can range from 100-120 g. Dough for mini buns can range from 20-40 g. Dough can also be made in different forms and ornamental designs such as croissant, bagels, donuts, buns, and pound bread or mini breads. Gas cells will progressively grow after dough mixing. Gas nuclei generated from mixing will grow to form visible cells in dough during resting and make up. Gas cells growth is slow but steadily and is dependent of dough temperature and time. The dough can then be frozen.

    [0032] Typically, dough products are frozen using a blast freezer in which a high fan speed is used thereby generating very high air velocity and enhancing heat transfer efficiency. Dough products will have a very high cooling rate in a blast freezer and therefore, undergo quick freezing. The blast freezer typically has a temperature of 20 F. to 30 F. Dough products are then stored at storage freezer. The storage freezer will typically maintain a temperature at 0 F. or below 0 F. Dough products are then subjected to a freeze-thaw cycling for at least one time. According to some embodiments, during freeze-thawing cycling, dough products are brought from the freezer to a temperature of 50-65 F., and allowed to thaw for several hours until the size of the dough products is about double of the original dough size. In some other embodiments of the present invention, the dough can undergo freeze-thaw cycling using a cooler at a temperature of 34-50 F. In some other embodiments, the dough can undergo a freeze-thaw at ambient temperature of 65-80 F. In some other embodiments, the dough can undergo freeze-thaw using a proofer at a temperature of 80-110 F. According to embodiments of the present invention, at least one freeze-thaw cycle is used to treat the dough in the present invention. In other embodiments of the present invention, multiple freeze-thaw cycles can be used to treat the dough. The dough is then refrozen after the freeze-thaw cycling.

    EXAMPLES

    [0033] Various embodiments of the formulas and methods according to present invention were tested in the following examples. Common lab and industrial equipment were suitable for making the dough. A Kitchen Aid mixer was used in mixing, and a home freezer was used as the storage freezer. A conventional baking oven and a 5 quarters steaming pot were used in the cooking test. Dough was mixed by mixing dry ingredients first, including flour, and other dry additives such as salt, sugar, non fat dry milk, and chemical leaveners, if any, and then mixing in wet ingredients, including yeast, water, syrups and shortening. Dough was mixed by hydrating dough at low speed followed by gluten development at high speed. Ingredients used include frozen yeast, which is a semi-dry yeast with a moisture content of about 20%, and compressed yeast, which has a moisture content of about 65%.

    Example 1

    [0034] Frozen dough products were prepared from dough formulas and methods of preparation according to embodiments of present invention, and quality of dough balls was compared.

    [0035] Sample Preparation:

    [0036] Dough formulations of about 1700 g each were prepared according to Table 1 using a stand mixer. Flour and dry ingredients were added and blended for 1 min prior to the addition of yeast and water. The content was mixed for 2 min at low speed, and 4 min at high speed. Dough was divided into 100 g dough pieces, and dough pieces were hand rounded into dough balls. The dough balls has a specific volume of about 1.3-1.5 mL/g. Dough balls after preparation were blast frozen to 20 F. and stored at 20 F. until applying treatments.

    [0037] Treatments:

    [0038] All samples except those of the test were transferred from 20 F. freezer at day 3 to 0 F. freezer and kept in 0 F. freezer until use. The test samples were treated with freeze-thaw cycling. During the freeze-thaw cycling treatment, the test samples were stored in the 20 F. freezer for 3 days, and then transferred from the freezer into room temperature in a covered container. The dough balls in the container were left at room temperature (70 F.) for 2 hours. During the thawing process, the size of the dough balls increased to about double the original size. The dough balls were then blast frozen and stored back in the 20 F. freezer overnight. The products was then transferred into a 0 F. freezer and stored until use.

    [0039] All formulas made similar dough balls and there were no apparent differences in the color, stickiness or cohesiveness of dough except that the treated dough balls are larger than the other frozen dough balls that were not treated. Dough balls prepared were used in the following cooking tests in Examples 2, 3, 4, and 5.

    Example 2

    [0040] Dough formulas were prepared according to embodiments of the present invention and quality of product was evaluated after baking. Frozen dough balls from Example 1 were stored at 0 F. for 2 weeks and then used for baking test and bakery quality evaluation.

    [0041] Treatment:

    [0042] A negative control was taken as the sample stored in freezer and transferred from the freezer directly to oven for baking without receiving any treatments prior to the baking. A positive control was prepared by thawing the dough balls at room temperature for 2 h in a covered container and then proofed for 30 min at 95 F. and 75% humidity immediately prior to baking. Therefore, the positive control was fermented and proofed before baking while the negative control was not treated prior to baking. The test sample of the present invention was the sample that has received freeze-thaw cycling treatments from Example 1, and was not fermented or proofed.

    [0043] Baking Test.

    [0044] A negative control, a positive control, and a test dough ball from Formulas A, B, C, D, and E, each from Example 1 were used in the baking test. The negative control was transferred directly from the freezer into the oven and baked at 400 F. for 20 min. The positive control was transferred from the proofer to the oven and was baked at 400 F. for 15 min. The test dough ball of the present invention was transferred from the 0 F. freezer into the oven and baked at 400 F. for 20 min. All breads after baking were allowed to cool down to room temperature for about 20 min. Bread weight and size were evaluated after cooling.

    [0045] Results of the baked bread evaluations are given in Table 2. As can be seen from Table 2, it was observed that the specific volumes of the test bread products were much higher than the negative control, and close to the positive control. The results indicated that the present invention with freeze-thaw cycling makes the dough ball able to be baked directly from frozen state without having to thaw, ferment and proof. The results also indicated that the present invention using a freeze-thaw pretreatment produced a dough ball that had a quality similar to those using thawing, fermentation and proofing prior to baking. It was concluded that the present invention produced dough balls that could be directly baked from frozen state and had volume much better than the negative control without any treatments, and close to the positive control that was thawed, fermented and proofed prior to baking.

    Example 3

    [0046] Dough formulas were prepared according to embodiments of present invention and quality of product was evaluated after steaming. Frozen dough balls from Example 1 were stored at 0 F. for 2 weeks and used for a steaming test and steamed bread quality evaluation.

    [0047] Treatment:

    [0048] A negative Control was transferred from the freezer to a steam pot without receiving any treatments prior to steaming. A positive control was also prepared. The positive control was treated by thawing the dough balls at room temperature for 2 h in covered containers, and then proofed for 30 min at 95 F. and 80% humidity, immediately prior to steaming. Therefore, the positive control was fermented and proofed before steaming while the negative control was not treated prior to steaming. The test sample of the present invention was the sample that received freeze-thaw cycling treatment from Example 1 and was not fermented or proofed.

    [0049] Steaming Test.

    [0050] A negative control, a positive control, and a test dough ball of Formula A, B, C, D and E from Example 1 were used in the steaming test. The negative control was transferred directly from the freezer into a steaming pot and steamed right from frozen state for 15 min. The positive control was transferred from the proofer into a steaming pot and steamed for 10 min. The test dough ball of the present invention was transferred from the 0 F. freezer directly into the steaming pot and steamed for 15 min. The steamed bread after steaming was allowed to cool down to room temperature for about 20 min. Steamed bread weight and volume were evaluated after cooling.

    [0051] Results of the steamed bread evaluations were given in Table 3. It was observed that the specific volume of the test bread products of present invention were much higher than those of the negative control, and close to those of the positive control. The results indicated that the present invention with freeze-thaw cycling makes the dough ball able to be steamed directly from frozen the state without having to thaw, ferment or proof. The results also indicated that the present invention using a freeze-thaw cycling pretreatment produced a dough ball that had a quality similar to dough balls undergoing thawing, fermentation, and proofing prior to steaming. It was concluded that the present invention produced frozen dough that can be directly steamed from a frozen state and had a volume close to control that was thawed, fermented, and proofed prior to steaming.

    Example 4

    [0052] Samples from Formula E of Table 1 in Example 1 were stored for 4 weeks in a 0 F. freezer and then used for the evaluation of visual color and volume of products after baking. A negative control, a positive control and the test sample were prepared and baked as described in Example 2. Photos of baked products from Formula E are given in FIGS. 1A-C. As can be seen from FIGS. 1A-C, directly baking a frozen dough without treatments resulted in a dense dough mass with little leavening actions (negative control). Fermenting and proofing the dough immediately prior to baking produced the best product with a golden brown color and smooth surface, and with a good volume. When a freeze-thaw cycle was used as treatment, an acceptable bread quality was obtained which was much better than the negative control, and was comparable to the positive control. It was concluded that the present invention produced a bread close to the product of prior art using a full fermentation and proofing prior to baking.

    Example 5

    [0053] Samples from Formula E of Table 1 in Example 1 were stored for 4 weeks in a 0 F. freezer and then used for the evaluation of visual appearance and volume of products after steaming. A negative control, a positive control and the test sample were prepared and steamed as described in Example 3. Photos of steamed products from Formula E are given in FIG. 2A-C. As can be seen from FIG. 2A-C, directly steaming a frozen dough without treatments resulted in a dense dough mass with gummy spots (negative control). Fermenting and proofing the dough immediately prior to steaming produced the best product with a shiny smooth surface and a good volume. The product also had a desired uniform cell openings.
