Oat has low gluten content, poor quality, high beta-glucan content, high viscosity and strong water absorption, and seriously influences the formation of dough network. When the addition amount of the oat flour exceeds 30%, the oat flour dough seriously deteriorates, the bread organization structure is compact, the honeycomb pores are small, and the bread specific volume is small. Patent application No. 202110109412.9 bread with high oat flour content and preparation method thereof, oat flour is added in 40-60 parts, optimization of bread texture is realized by adding 0.00015-0.00045 part of beta-glucanase, but improvement of dough proofing volume is not mentioned, beta-glucan content in oat is reduced by using beta-glucan enzymolysis, and health efficacy is greatly reduced. Patent application No. 201410087197.7 oat flour addition amount of 'a high fiber oat bread' exceeds 50%, but the bread specific volume is 1.5-2.5 mL/g, and the problem of small volume of the oat bread is still not solved. Patent application No. 201711426742.0 & ltbread with sweet potato and oat & gt, the addition amount of oat is not less than 10%.

Example 5
The volume of oat bread was measured according to the rapeseed isovolumetric displacement method in GB/T20981-2007 for the finished products obtained in examples 1 to 4 and comparative examples 1 to 4, and the specific volume (mL/g) = volume of bread (mL)/mass of bread (g) was measured, and the measured data are shown in table 1.
TABLE 1 specific volume of bread prepared in examples 1 to 3 and comparative examples 1 to 4
As can be seen from Table 1, the bread product prepared in example 1 has the largest specific volume, the addition of oat flour can adversely affect the network structure strength of the dough, and the specific volume of the bread gradually increases with the increase of the addition amount of the oat flour, and when the content of oat exceeds 70% (comparative example 1), the specific volume of the bread is lower than 3.0mL/g.
The oat contains a large amount of beta-glucan, and the oat absorbs water competitively with a gluten network to block the formation of gluten. The results of examples 1 to 4 demonstrate that oat bread has a good specific volume within the scope of the claims. Compared with the example 3, the comparative example 2 and the dough stage do not use the processes of adding water and standing for several times, and the specific volume is reduced from 3.61mL/g to 3.23mL/g. The bread specific volume increases with the increase of the water adding times (examples 2-3 and comparative examples 2-3), but the increase of the bread specific volume is no longer obvious after the water adding times exceed 3 times; too long a resting time (comparative example 4) would rather result in a decrease in the bread specific volume, probably due to yeast fermentation.
On the other hand, the increase of the number of times of adding water and the standing time leads to the increase of the production period and the reduction of the production efficiency, and finally leads to the increase of the production cost. Comprehensively, the times of adding the feed liquid in the dough kneading stage for several times are suitable for 2 to 3 times, and the secondary standing time is suitable for 5 to 10min.
The bread products prepared in examples 1 to 4 and comparative examples 1 to 4 were sliced after cooling for 2 hours, scanned with a resolution of 600dpi, and images of the center of the bread at 3cm × 3cm were selected, analyzed with image J software, and the Otsu threshold technique was selected as a threshold value, and a distinguishable radius range was set to 50 to 50000 μm, and the following parameters were obtained by analysis: number of pores (Count), average pore Area (AS), average pore radius AR, and pore consistency CD. The measured data are shown in table 2.
Table 2 bread core pore distribution obtained in examples 1 to 4 and comparative examples 1 to 4
As can be seen from Table 2, the distribution of the air holes of the bread core is closely related to the bread texture, the surface area of the air holes and the surface fraction of the air holes are too small, the consistency of the air holes is too high, the number of the air holes is too large, and the correspondingly prepared bread core has small and dense air holes, poor texture, low filling power and low softness. As shown in Table 2, when the amount of oat flour added was too high (control 1), the bread texture was not very porous. The pore distribution values of examples 1 to 4 are within reasonable ranges. Compared with example 3, comparative example 2 has a large number of pores, a small average area of pores, and a low surface fraction of pores, the indexes related to comparative example 3 are moderately improved, and comparative example 4 has a certain degree of reduction, which indicates that the times of adding water in several times and the standing time need to be in an appropriate range. This is consistent with the specific volume results in Table 1, which shows that the invention has outstanding effect of the fractional water addition and standing process in the dough kneading stage.
The bread products obtained in examples 1 to 4 and comparative examples 1 to 4 were cooled at room temperature for 2 hours, cut into uniform slices of 10mm with a slicer, and the two slices in the middle were selected for determination of the full texture of the bread core. Setting experimental parameters: the probe model P/25, the speed before the test is 1.0mm/s, the test speed is 3.0mm/s, the speed after the test is 3.0mm/s, the deformation amount is 50%, the induction force is 5g, and the time interval between two times of compression is 5s. The measured texture data are shown in table 3.
TABLE 3 texture measurement data of the breads obtained in examples 1 to 4 and comparative examples 1 to 4
| Hardness of | Elasticity | Cohesiveness | Adhesiveness to glue | Chewiness of the product | Recovery property | |
| Example 1 | 418.57 | 0.546 | 0.820 | 371.19 | 180.08 | 0.368 |
| Example 2 | 471.25 | 0.553 | 0.728 | 353.88 | 190.16 | 0.342 |
| Example 3 | 447.59 | 0.541 | 0.771 | 357.19 | 188.73 | 0.359 |
| Example 4 | 529.95 | 0.699 | 0.699 | 333.58 | 208.88 | 0.339 |
| Comparative example 1 | 541.18 | 0.711 | 0.613 | 309.27 | 218.32 | 0.303 |
| Comparative example 2 | 501.27 | 0.673 | 0.655 | 324.68 | 197.32 | 0.314 |
| Comparative example 3 | 438.84 | 0.531 | 0.782 | 366.03 | 191.28 | 0.371 |
| Comparative example 4 | 458.77 | 0.540 | 0.769 | 341.21 | 190.07 | 0.362 |
As can be seen from Table 3, the eating quality of the bread was positively correlated with the cohesiveness, adhesiveness and restorability of the texture data, and negatively correlated with the hardness and elasticity. As seen from the data in Table 3, examples 1 to 4 all had good texture data values. Compared with the example 3, the bread hardness value of the comparative example 2 is high without using the divided water adding and standing process, but the values of cohesiveness, adhesiveness and recoverability are low; in the comparative example 3, the times of adding the liquid are increased, and the bread texture is improved to a certain extent; however, comparative example 4 was allowed to stand for too long to adversely affect the texture of bread. Comprehensively considering the production efficiency and the production cost, verifying that the times of adding the feed liquid in the flour mixing stage for multiple times are suitable for 2-3 times, and the time for standing for the second time is suitable for 5-10 min.
