Embodiment Construction

[0067] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0068] The production method of this nanoscale rice starch, the raw material of production is rice, comprises the steps:

[0069] a. Preparation of rice starch: first soak the rice in 0.8% sodium hydroxide aqueous solution for 16-20 hours, stir it every 4 hours, pour out the soaking liquid, pass through a colloid mill after beating with a beater, and then soak with 0.8% sodium hydroxide aqueous solution After 12-16 hours, pour out the soaking solution, add deionized water, centrifuge, pour off the supernatant, and repeat washing 3-5 times; after adding deionized water for the last time, adjust the pH value to neutral, centrifuge, and the resulting precipitate It is rice starch; in this embodiment, first soak the rice in 0....

Abstract

The invention provides a production method of nanoscale rice starch. The technical problems that a traditional smashing mode is adopted in an existing preparation method, preparation time is long and production cost is high are solved. The method uses rice as the production raw material and includes the following steps of a, preparing rice starch; b, conducting homogenizing treatment; d, conducting smashing; e, conducting detecting. The method has the advantage of being low in production cost.

Description

technical field [0001] The invention relates to a production method, in particular to a production method of nanometer rice starch. Background technique [0002] Rice starch has some properties that other starches do not have. Compared with other cereal starch granules, rice starch granules are very small and uniform in size. The gelatinized rice starch absorbs water quickly, the texture is very smooth like cream, has a fatty taste, and is easy to spread. In addition to its fat-like properties, waxy rice starch also has excellent freeze-thaw stability, preventing syneresis during freezing. [0003] After searching, for example, Chinese patent literature discloses a preparation method of nano-starch microspheres [application number: 201510151917.6; publication number: CN 104785179A]. The preparation method of this nano-starch microsphere comprises the steps of: (1) dissolving amylose in an alkali solution and stirring to obtain a suspension; (2) freezing the suspension obt...
