Problems solved by technology

Due to the irregular shape, some irregular leftovers will inevitably be produced in the process of potato production, cutting or finishing according to product specifications. At present, domestic manufacturers usually treat them as waste, which not only has low added value, but also consumes resources. Waste and Environmental Pollution
Although domestic research on the comprehensive utilization of potato processing by-products has started and some progress has been made, the overall technological level has not improved significantly, especially the proportion of research results that have been commercialized is very small

Abstract

The invention provides potato-bread frozen dough and a preparation method thereof. The potato-bread frozen dough comprises the following components: potato powder and wheat flour, wherein the weight rate of the potato powder to the wheat flour is (10-40): (90-60). The preparation method comprises the following steps of: mixing the potato powder and the wheat flour, and adding water as well as an appropriate amount of yeast, sugar, salt, butter, eggs and the like into the obtained mixture so as to obtain dough; and then, after carrying out partitioning, forming and pre-fermenting on the dough, freezing the dough and then taking out the dough to carry out packing, and carrying out freezing storage on the dough. The potato-bread frozen dough (the viable count of yeasts in the frozen quality guarantee period is greater than or equal to 107 cfu / g) produced by using the method disclosed by the invention can be subjected to unfreezing, re-fermenting and baking so as to prepare fresh bread as required, and the technique facilitates the production management of bread and the freshness preservation of products; in addition, due to the addition of the potato powder, the nutritive value of bread is improved, the texture and taste of bread are improved, and the comprehensive utilization and development of potato processed by-products are facilitated, thereby having great significance in improving the additional values thereof.

Description

technical field [0001] The invention relates to a baking product processing method and products in the light industry, in particular to a cold (quick) frozen potato bread dough and a preparation method thereof. Background technique [0002] Compared with other cereal foods, bread has gradually become a popular food because of its high nutritional value, convenient eating, and high digestibility. People have higher and higher requirements for bread nutrition and diversification. However, bread produced by traditional methods It is very easy to age after baking, resulting in deterioration of flavor, reduction of nutritional value, and short commodity period, which directly affects the quality and sales of bread. Therefore, how to adopt effective methods to delay the aging of bread has become a research hotspot of scholars from all over the world. [0003] my country is a big potato producer. Except for fresh food, most potatoes are used for the production of starch, potato ch...
