Abstract

The invention discloses a method for preparing glutinous rice flour through freeze grinding. The method comprises the following steps: removing impurities from glutinous rice, and carrying out cleaning and draining so as to obtain cleaned glutinous rice; soaking the cleaned glutinous rice with water, and carrying out draining and crushing so as to obtain a crushed glutinous rice material; subjecting the crushed glutinous rice material to pre-freezing treatment, then subjecting a pre-frozen crushed glutinous rice material to superfine grinding in a frozen state so as to obtain a ground glutinous rice material, and carrying out packaging; and recovering the temperature of the packaged ground glutinous rice material to a room temperature so as to obtain the glutinous rice flour. According tothe invention, after the crushed glutinous rice material is subjected to pre-freezing, the pre-frozen crushed glutinous rice is ground in a frozen state, so the average particle size and the broken starch amount of the glutinous rice flour are reduced; the glutinous rice flour is small in particle size and uniform in distribution; the specific surface area of the glutinous rice flour is increasedto a great extent; water absorption properties, solubility, freeze-thaw stability and the like of the glutinous rice flour are improved; and the comprehensive quality of the glutinous rice flour is improved.

Description

Technical field

[0001] The invention relates to the technical field of food processing, in particular to the technical field of glutinous rice flour processing, in particular to a method for preparing glutinous rice flour by freezing and crushing. Background technique

[0002] Glutinous rice is mostly used in me to make traditional special flavor foods. With the development of modern society and the improvement of people’s living standards, people’s demand for food flavor, quality and variety is increasing. Glutinous rice has also changed from the single application of traditional food to processing. The use of glutinous rice flour continues to expand, especially the emergence and popularization of modern glutinous rice flour quick-frozen foods, and the transformation and utilization of starch by modern biotechnology, which have continuously increased the demand for glutinous rice flour. At present, my country's glutinous rice flour processing industry is still in its growth stag...
