Processing technology of frozen powder-dipped pork-onion string

The invention relates to a processing technology of frozen powder-dipped pork-onion string, belonging to the technical field of food processing. The processing technology comprises the following steps of: flavouring pork; slicing the pork; slicing onions; stringing the pork and the onions for forming; dipping a pork string with base powder, starch slurry and bread making powder; and quickly freezing. The processingtechnology is characterized in that the pork flavouring step is as follows: injecting flavouring liquid into the pork by adopting a saline water injector, and rolling for flavouring by adopting a rolling machine. The production process can fast uniformly distribute the flavouring liquid into meat tissues, thereby solving the technical problems of long flavouring time and nonuniform flavouring liquid distribution of the traditional pork; after the flavouring liquid is injected into the pork, the pork is automatically beaten in the rolling machine and mutually extruded so that meat proteins are decomposed into water-soluble proteins which can be assimilated by human bodies easily, and the flavouring liquid and the meat proteins are mutually fused to achieve the purposes of meat quality tenderization, good taste and high finished product yield.
