Drawings
Fig. 1 is a flow chart of a processing method of the nutritional lotus root starch provided by the invention.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments.
Referring to fig. 1, a processing method of the nutritional lotus root starch comprises the following steps: s1, selecting raw materials, namely selecting lotus roots with dark colors, short and thick shapes and more lotus root filaments as raw materials for preparing lotus root starch, wherein the lotus root starch content is higher;
s2, processing raw materials, cleaning and peeling the selected lotus roots, specifically cleaning the surfaces of the lotus roots, removing black lotus rhizome nodes at two ends of the lotus roots and the skin on the surfaces of the lotus roots, cleaning the lotus roots Kong Xi to prevent the quality of lotus root starch from being affected after later powdering, slicing or cutting the lotus roots into small pieces, and avoiding the loss of starch without cleaning after cutting;
s3, crushing the lotus root slices for one time, putting the lotus root slices into a crusher for crushing, and putting the crushed lotus root slices into a grinder for grinding to obtain finer lotus root mud, so that starch in lotus roots can be better separated out;
s4, curing, namely putting lotus root mud into cooking equipment to be steamed, namely tiling the lotus root mud and heating the lotus root mud by utilizing steam, wherein the heating temperature is not more than 55 ℃, because the temperature is about 55 ℃, starch particles absorb water and expand and are basically half-cooked after being heated to within 55 ℃, then cooling the steamed and half-cooked lotus root mud, and then cutting the lotus root mud into small blocks or slices;
