Abstract

The invention discloses a blending method of high-quality indica rice. The blending method comprises the steps of: selecting 3-4 indica rice raw materials with a moisture mass content of 12%-16%, an amylose mass content of 15%-24%, a crude protein mass content of less than or equal to 10% and a crude fat mass content of less than or equal to 3%, compounding the indica rice raw materials according to a mass content of 20%-60% of each raw material, thus obtaining compounded rice; measuring the start temperature and the enthalpy value of the compounded rice by a differential calorimetric scanner, and measuring the final viscosity and the retrogradation value of the compounded rice by a rapid viscosity analyzer; and finally tasting and scoring the compounded rice. The compounded rice product produced by the method involved in the invention has stable quality, and can reach above the third-class eating quality index requirements of high quality rice specified in a national standard of rice.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a blending method of high-quality indica rice. Background technique [0002] Compounded rice refers to the finished rice made by mixing different processing varieties, edible varieties and nutritional varieties of rice in a certain proportion. Rice preparation technology is a kind of rice finishing technology, which has been paid more and more attention by rice processing enterprises. In the existing rice preparation technology, some only pay attention to the processing quality and ignore the cooking, taste and nutritional index control of the product; although some pay attention to the cooking quality, they only set the recipe directly after cooking and tasting, resulting in the inconsistency of the recipe. Human error is relatively large, and the overall quality of the prepared rice is uneven. At the same time, there are many varieties of rice in our count...
