Abstract

The invention discloses a preparation method of buckwheat vermicelli. The preparation method of the buckwheat vermicelli comprises the following steps: (1) selecting materials; (2) soaking buckwheat grains; (3) carrying out draining; (4) carrying out ice-temperature cold-air drying; (5) carrying out steam-blasting; (6) carrying out grinding so as to obtain powder; (7) carrying out drying; (8) preparing pulp; (9) carrying out precipitating; (10) carrying out steaming; (11) carrying out extruding; (12) carrying out aging; and (13) carrying out drying, and performing magnetic separation, sterilization and packaging so as to obtain the buckwheat vermicelli. Pretreatment is performed on the buckwheat grains by utilizing an ultrasonic technology, a steam-blasting technology and an ice-temperature cold-air drying technology; and thus, the prepared buckwheat powder is a brand new product which balances improved taste and preserved functions of buckwheat flour. On such basis, the steps of preparing pulp, carrying out precipitating, carrying out steaming, carrying out extruding, carrying out aging and carrying out drying are performed, so that the prepared finished products of the buckwheatvermicelli are not liable to break, flexible and smooth in taste.

Description

technical field [0001] The invention relates to the field of food processing, in particular to buckwheat vermicelli and a preparation method thereof. Background technique [0002] Buckwheat, aliases: sweet buckwheat, rye, triangular wheat, etc.; annual herb. Stems erect, 30-90 cm tall, upper branched, green or red, with longitudinal ribs, glabrous or with papillae along longitudinal ribs on one side. Leaves triangular or ovate-triangular, 2.5-7 cm long, 2-5 cm wide, apex acuminate, base heart-shaped, with papillae on both sides along the veins. Buckwheat is a short-day crop and likes to be cool and humid. It is not resistant to high temperature and dry wind, and is afraid of frost. Buckwheat is distributed in most parts of China, and also in Asian and European countries. Buckwheat is sweet in nature and cool in taste, which has the effect of appetizing and widening intestines, lowering Qi and eliminating stagnation. It can treat colic intestinal syndrome, gastrointestina...
