Abstract

The invention relates to a method for improving viscoelastic behavior for bread dough by employing complex enzyme preparations containing recombined lipase and belongs to the technical field of food processing. The method includes uniformly pre-mixing high and pouring gluten wheat flours, active dry yeasts, the recombined lipase, lipoxygenase, transglutaminase and laccase in a stirring bowl, then adding water, egg liquid, white sugars and salts in the mixture to stir, and adding shortening in the mixture to stir, so that the bread dough is achieved; after standing, dividing and rolling the bread dough; placing the dough in a fermenting box for fermentation; finally placing the fermented dough in an oven to achieve the final product. By applying the complex enzyme preparations such as the recombined lipase, the lipoxygenase, glucose oxidase, the transglutaminase and the laccase, gluten network structure of the bread dough is increased, and the viscoelastic behavior is improved, thus product quality is enhanced, and the problem of poor bread quality caused by insufficient flour strength during bread production is solved; and meanwhile, the chemical gluten strengthening agent is replaced by the biological enzyme preparations applied to fermented flour food, thus food safety is enhanced, and the method is safe.

Description

technical field [0001] The invention relates to a method for improving the viscoelastic properties of bread dough by using a compound enzyme preparation containing recombinant lipase, which belongs to the technical field of food processing. Background technique [0002] Potassium bromate was once a more commonly used additive in dough-based fermented foods, which can increase the viscoelastic properties of dough. However, later studies have shown that potassium bromate has carcinogenic effects, and my country has banned it in 2005. The production of bread requires flour to have strong viscoelastic properties to keep the gas generated during stirring, fermentation and baking. [0003] Enzyme preparation is a new type of food additive generally recognized as safe (GRAS). Product shelf life and other aspects have a good effect. In the final baking process, most of the enzymes are denatured and inactivated due to high temperature, and will not cause any toxic side effects to ...
