Abstract

The invention discloses a method for preparing instant rice by taking broken rice as a raw material. According to the method, the broken rice is used as a main material, modified starch, guar gum andmonoglyceride are used as subsidiary materials, the materials are subjected to mixing and modifying, extrusion forming, drying, and cooling so as to prepare the instant rice with the advantages of being economical, environment-friendly, convenient to eat, full in particles, good in glossiness, uniform in particle shape, and good in taste; and the problem of retrogradation aging after the instant rice is cooked is effectively inhibited, and the reconstitution property of the instant rice is improved.

Description

technical field [0001] The invention relates to the field of preparation of instant rice, in particular to a method for preparing instant rice using broken rice as a raw material. Background technique [0002] Broken rice is a by-product of rice processing. Rice processing companies pursue the precision and whiteness of rice, and the milling intensity is getting higher and higher. During the milling process, a large amount of broken rice is produced. Because the taste of broken rice is poor, Most were separated. The output rate of its polished white rice in most rice processing enterprises is only about 55%, and the output of broken rice is about 15%. At present, this part of broken rice is usually used as feed, and its economic value is 1 / 3-1 / 2 lower than that of polished white rice. In fact, besides the broken endosperm part, broken rice also contains most of the rice shed during rice processing Embryo, while rice germ contains most of the protein, fat, vitamins and othe...
