- the dough is at least partially thawed by placing the frozen dough for at least one hour (e.g., 1-48 hours and any value or range therebetween) in an environment having a temperature of less than about 50F (e.g., 33°F-45 ).
- the dough can be proofed by placing the dough into an environment having a temperature of about 55F to 15 OF (e.g., 90F-100F) having a relative humidity of about 50% to 95% (e.g., 80%-90%) until the dough reaches a desired proofed height.
- the proofed dough can optionally be rested by placing the dough in an ambient temperature (e.g., 65F to 85F) for about 1-100 minutes (e.g., 5-15 min).
- the dough is generally placed on a rack or in a pan and baked at a temperature of at least about 250F (e.g., 325F-390F) for about 5-100 minutes (e.g., 20-40 min.).
- the dough can optionally be exposed to steam for at least 2 seconds (e.g., 2-20 sec). The steam process, when used, typically occurs at the beginning of the baking processing.
- the farinogram is a physical test that measures and records the resistance, as torque, of a flour/water mixture.
- the absorption is the amount of water mixed to a fixed amount of dry solids of flour to center the farinograph curve on the 500-Brabendar Unit (BU) line as a standard consistency to compare flour, either different flours or flours from different crop years.
- the development time is an indicator from the moment water is added until the dough reaches maximum consistency.
- Two farinogram properties that are used to evaluate flour strength are stability and mixing tolerance.
- Stability is a time indicator that the dough maintains maximum consistency and is defined as the difference in time between arrival, which is the time when the resistance curve reaches 500 BU, and departure, which is the time when the resistance curve drops below 500 BU.
- Mixing tolerance index is the difference in consistency BU value at the top of the curve at peak development time and the consistency value at the top of the curve 5 minutes after peak.
- Example 2 is a comparison of dough that includes the heat-treated flour of the present invention to dough that includes VWG.
- the dough that includes the heat-treated flour is identified as strengthened dough.
- EXAMPLE 2 Strengthened Flour Using VWG Compared to Using Strengthened Flour.
- the results in Table 2 illustrate a comparable increase in absorption to a consistency of 500 BU between the VWG containing dough (Sample 2) and the dough containing the heat- treated or strengthened flour (Samples 3-5) when VWG and the strengthened flour were added to the untreated flour.
- the control flour with VWG (Sample 2) and the control sample with strengthened flour (Samples 3-5) had increased strength (stability) as compared to dough formed only with the control flour.
- the increase in stability was not quite as high as VWG; however, the stability increased with increased percentage of the strengthened flour (3 wt% vs. 4.5 wt%), as well as strengthened flour formed from a higher protein flour (3 wt% strengthened flour from 10.7% protein flour vs. 3 wt% strengthened flour from 13.2% protein flour).
- EXAMPLE 3 Frozen Dough Product Bake Evaluation: Use of VWG Compared to use of Strengthened Flour.
- the strength of flour and dough is important in frozen dough products during the frozen storage of the dough so as to counter the effects ice re-crystallization on gluten integrity.
- the required dough strength to maintain quality of the dough during frozen storage is obtained through a combination of high protein wheat flour having high stability and traditional dough strengthening ingredients, such as VWG, potassium bromate, azodicarbonamide (ADA), stearoyl lactylates, and DATEM.
- the frozen dough was removed from the freezer a day prior to baking.
- the frozen samples for each product were placed on line trays, and the trays were then placed into a retarder cabinet at about 37°F (2.8°C) for 15 hours overnight.
- the samples were then removed from the retarder and, in the case of the whole wheat loaf samples, immediately placed into oil-sprayed loaf pans.
- the samples were then placed into a proofer cabinet at about 92°F (33.3°C) and at about 85% relative humidity until the samples reached a desired proofed height.
- the samples were then removed from the proofer and allowed 10 minutes of ambient temperature floor time prior to placing the samples in a rack oven to bake.
- the baking was conducted at about 340°F (171.1°C) for about 10 minutes and with about a 10 second steam at the beginning of the baking process.
- the baking was conduct at about 365°F (185°C) for about 12 minutes and with about a 7 second steam at the beginning of the baking process.
- the baking was conducted at about 375°F (190.5°C) for about 25 minutes and with about a 10 second steam at the beginning of the baking process.
- the baked samples were allowed to cool for at least 1 hour before weight and volume measurements were taken on the Tex Vol Instrument (model BVM- L450).
- the VWG and SF samples for each product were retarded, proofed, and baked on the same trays so that such samples experienced the same conditions throughout the proofing and the baking process.
- the baked-specific- volume (BSV) for each of these products is illustrated in Figs.2, 4 and 7. Illustrations of these products are shown in Figs. 1, 3, 5 and 6.
- the BSV is an inverse- density parameter calculated from the baked volume divided by the baked weight, and is commonly used as quality index of the baked performance of a product.
- bread products made from a dough that has insufficient strength and/or has poor gluten integrity due to multi-grains or bran in the formulas results in an increased dense crumb structure, and hence has a low BSV.
- the sweet rolls made with SF had significantly higher BSV and baked volumes than the sweet rolls made with VWG throughout 150 days frozen storage.
- the whole wheat rolls and whole wheat bread loaves made with SF had comparable BSV and volumes to the whole wheat rolls and whole wheat bread loaves made with VWG throughout 150 days frozen storage. This performance throughout the frozen storage is a very good indicator of how effective SF can be as a dough strengthening ingredient as compared to VWG.
- Example 4 is a comparison of different amount of VWG in the dough as compared to a dough that includes SF.
- EXAMPLE 4 Frozen Dough Product Bake Evaluation: Optimized VWG vs. Reduced VWG vs. Strengthened Flour.
- Figs. 8 and 9 The importance of obtaining the optimum dough strength for a particular baked product is illustrated in Figs. 8 and 9 and Tables 7-9.
- Whole wheat breads require additional gluten strength to help with bake volume performance due to the presence of bran in the product.
- frozen dough products need additional strength to counter damaging effects to gluten during the freezing and frozen storage.
- This example compared whole wheat, frozen dough samples with 2.5% VWG, 1% VWG, and 2.5% SF from 10.7% protein flour. The whole wheat bread samples were about 4 oz. and were proofed and baked in pup loaf bread pans.
- the dough samples were placed on lined trays, and the trays were placed in a retarder cabinet at about 37°F for about 15 hours. The samples were then taken out of the retarder and immediately placed into the pup loaf pans and sprayed lightly with canola oil. The samples in the pan were then place into a proofer cabinet at about 92°F and at about 85% relative humidity. Proofing was complete when the dough height reached about 0.5 cm above the rim of the loaf pan. The proofed samples were given about 10 minute floor time in ambient temperature prior to baking. The samples were then baked in a rack oven at about 375F for 16 minutes and with 7 seconds of steam at the beginning of the baking process.
- the negative control samples [(-) Control (1% VWG)] show considerably lower baked volume and BSV as compared to the control [(Control (2.5% VWG)] and the test samples [Test (3% SF)].
- the bread loaf profiles illustrate that the negative control samples do not have enough strength as shown by the 'saddle' effect where the center of the loaf dips down and is not able to support a desirable 'domed' shape loaf.
- the test samples using SF have better volume and BSV than the control, and the bread loaf and slice profile show comparable characteristics to the control.
- Example 5 is a comparison of fresh bake whole wheat bread loaves that include 5% VWG or 5% SF.
