Embodiment 1

[0024] A processing method for extracting starch from rice, comprising the steps of:

[0025] (1) Treatment liquid preparation:

[0026] Each material is weighed according to the corresponding weight part to be prepared into a treatment solution, and the weight percentage of each material component of the treatment solution is: 0.1% sodium hydroxide, 0.02% sodium dodecylbenzenesulfonate, 0.01% fatty alcohol polyoxyethylene Ether, 0.02% sodium sulfate, 0.02% diacetyl tartrate fatty acid glyceride, 0.01% monoglyceride stearate, the balance is water;

[0027] (2) Rice crushing:

[0028] After the rice is dedusted and impurity-removed with clear water, it is dried and pulverized and passed through 120 meshes to obtain rice flour for subsequent use;

[0029] (3) Soaking treatment:

[0030] Mix the rice flour obtained in step (2) with the treatment solution prepared in step (1) at a weight ratio of 1:8 to obtain a mixed solution, then heat to keep the temperature of the mixed sol...

Abstract

The invention discloses a processing and treatment method for extracting starch from rice, and belongs to the technical field of rice processing. The processing and treatment method particularly comprises the following steps: (1) preparing a treatment solution; (3) crushing rice; (3) performing soaking treatment; (4) performing low-temperature treatment; (5) performing ultrasonic treatment; (6) performing starch separation and drying. After the adoption of the method disclosed by the invention, the starch extraction rate is relatively high, the loss rate of the starch is stabilized to be less than 2%, the content of protein in the extracted starch is less than 0.55%, the purity and the use characteristics of the starch are well ensured, and relatively high production and use values can be made.

Description

technical field [0001] The invention belongs to the technical field of rice processing, and in particular relates to a processing method for extracting starch from rice. Background technique [0002] my country produces a large amount of starch every year, 80% of which is corn starch, 14% is cassava starch, 6% is starch produced by other potatoes, cereals and wild plant resources, and the output of rice starch is only 1%. However, the starch content in rice is relatively higher than other grains, about 70%. At the same time, there are more than 240,000 kinds of rice in the world. Different kinds of rice starch have a wide distribution range of amylose content (from 1 to 30%), forming different functional properties, and have different gelatinization temperature and aging. characteristics, processing stability, etc. [0003] Among all starch types, the average particle size of rice starch granules is the smallest at 2-8 μm. It is precisely because of this small particle siz...
