As can be seen from Table 1, the quick-frozen vegetable corners of example 1 have a low hardness, a good elasticity and a good toughness, and the lower the hardness, the higher the elasticity, the higher the toughness, and the better the mouthfeel of the dough sheet. It can be seen from the above data that the texture of the dough sheet prepared in example 1 is superior to that of comparative examples 1 to 5, which shows that only the blanched dough and the medium gluten flour are used in combination, under the combined action of the vegetable-rib modifier and the emulsified oil, the prepared quick-frozen vegetable-rib dough sheet is soft and elastic and has better taste, the medium gluten flour is omitted and only the blanched dough is used, the prepared quick-frozen vegetable-rib is smaller in hardness and poorer in elasticity and toughness, the medium gluten flour is the flour with the protein content of about 11%, the medium gluten flour is replaced by other flour and then is larger in hardness and poorer in elasticity and toughness, and the dough sheet prepared by only using the medium gluten flour and the blanched dough in combination has better taste. The texture quality of the comparative example 2 is between the comparative example 6 and the comparative example 7, the texture quality of the comparative example 3 is between the comparative example 8 and the comparative example 9, and the result shows that after the medium gluten flour is replaced by the low gluten flour or the high gluten flour, no synergistic effect exists between the medium gluten flour and the rapeseed angle modifier and the emulsified oil, the synergistic effect can be achieved only by combining the medium gluten flour, the rapeseed angle modifier and the emulsified oil, the soft and slightly waxy mouthfeel of the rapeseed angle skin is guaranteed, the elasticity and the toughness are good, the mechanical processing performance of the rapeseed angle skin is improved, and the industrial production requirements are met.
After freeze-thawing the quick-frozen vegetable horns of example 1 and comparative examples 1 to 8 repeatedly, the frost cracking rate was counted, and the results are shown in table 2.
TABLE 2
Figure BDA0001680060480000111
As can be seen from the above table, the freeze-fracture rate of the quick-frozen vegetable horns in the example 1 is zero, the freeze-fracture rate of the comparative examples 1 to 5 is higher than that of the example 1, the middle gluten flour in the dough sheet is omitted and only the dough is used for ironing, or the middle gluten flour is replaced by the flour with other protein content, the freeze-fracture rate is obviously increased, the dough sheet is added with the ironing surface and the middle gluten flour for use, the stability of the dough sheet is improved, the freeze-fracture rate is reduced, the freeze-fracture rate of the comparative example 2 is between the comparative example 6 and the comparative example 7, the freeze-fracture rate of the comparative example 3 is between the comparative example 8 and the comparative example 9, the middle gluten flour is replaced by the low gluten flour or the high gluten flour, the synergy between the dough sheet and the emulsification oil is avoided, the synergy exists between the middle gluten flour and the vegetable horn improver, the synergy exists between the oil, the synergy disappears after the middle gluten flour is replaced by the flour of other types, and the stability of the dough sheet is poor, the frost cracking rate increases.
According to the invention, the dough sheet is added with the scalded flour and the medium gluten flour, and then the rapeseed improver and the emulsified oil are matched, so that the dough sheet has good elasticity and toughness, meets the requirement of industrial production, has good edible taste and stable dough sheet property, and is not easy to frost crack.
