Preparation method of instant lotus root starch brewed in water with stirring

The invention discloses a preparation method of instant lotus root starch brewed in water with stirring, and belongs to the field of processing of lotus root starch in food engineering technology. Thelotus root starch which can be brewed at will is characterized in that when in use, only normal-temperature (warm, cool and cold) water is needed to be added for brewing with stirring, so that traditional methods that lotus root starch has to be brewed with boiling water for cooking is replaced. The preparation method of the lotus root starch which can be brewed at will comprises the following steps: firstly, cooking lotus root starch, and then subjecting the lotus root starch to crushing, bonding and granulation. when in use, normal temperature (warm, cool and cold) water is added for brewing with stirring, the lotus root starch after being brewed and stirred can quickly absorb water, be gelatinized and expanded into semitransparent sticky gel, and the lotus root starch is fine in mouthfeel and smooth and palata
