Stuffing modifier, soup-stock stuffing, double-layer soup-stock steamed stuffed bun and preparation method thereof
Technical Field
The invention relates to the technical field of wheaten food processing, in particular to a filling modifier, a broth filling, a double-layer soup-retaining steamed stuffed bun and a preparation method thereof.
Background
The steamed stuffed buns are lifted, and the fresh breakfast steamed stuffed buns which are visible everywhere in the morning are firstly thought to be fresh and flowing oil. In order to conform to the rhythm of life of modern people for fast consumption, quick-frozen instant foods are more and more popular with mass consumers, such as quick-frozen steamed stuffed buns, quick-frozen dumplings and the like, and the problem of soup retention is a problem that quick-frozen steamed stuffed bun products cannot break through. The processing technology of the existing quick-frozen steamed stuffed bun products comprises the following steps: the formed and proofed product is steamed and then quickly frozen for storage, and consumers need to re-steam and heat before eating the product. The soup in the stuffing of the product can permeate into the wrapper when the product is cooked for the first time, and then the wrapper is stored by quick freezing, so that the problems that the stuffing does not have the soup when the consumer re-steams and eats the product, the wrapper is sticky due to the absorption of the soup in the stuffing, the taste is poor and the like are caused. Based on the current situation of the existing quick-freezing industry, the invention innovates the stuffing and the wrapper of the quick-freezing stuffing food and the preparation process thereof, and improves the soup content of the stuffing and the overall taste of the stuffing food after reheating.
