Problems solved by technology

However, in the process of dehulling, it will cause loss of grain, which has a great impact on the integrity of the finished product after dehulling.
In addition, soaking and peeling is also a commonly used grain peeling method at present. In the past, soaking in normal temperature water was usually used, and the peeling rate was low and the effect was not good. It has been found that soaking sorghum in soaking agent can remove the sorghum seed coat, but different soaking Agents and soaking methods have a great influence on the dehulling effect of sorghum

Embodiment 1

[0076] A sorghum peeling method, comprising the following steps:

[0077] The first step is to pick clean and free sorghum raw materials, add water (just submerge the sorghum), and soak at 4°C for 12 hours;

[0078] In the second step, after soaking, filter with a sieve, centrifuge at 1000r / min for 10min with a dehydration centrifuge, and dry the sorghum;

[0079] The third step is to add 1.5 ml of NaOH solution with a concentration of 6% to 1 g of sorghum according to the ratio of material to liquid: 1:1.5;

[0080] The fourth step is to place the mixed solution in a beaker, and use an ultrasonic cleaner to perform ultrasonication under the condition of a water bath. The liquid level of the water bath exceeds the mixed liquid level. During the ultrasonic process, the stirrer stirs the mixed solution synchronously, and the power of the ultrasonic cleaner is set to 80w , The temperature is set to 50°C, the stirring speed of the stirrer is 160r / min, and the ultrasonic and stirr...

Embodiment 2

[0086] A sorghum peeling method, comprising the following steps:

[0087] The first step is to pick clean and free sorghum raw materials, add water (just submerge the sorghum), and soak at 4°C for 18 hours;

[0088] In the second step, after soaking, filter with a sieve, centrifuge at 3000r / min for 10min with a dehydration centrifuge, and dry the sorghum;

[0089] The third step is to add 2ml of NaOH solution with a concentration of 8% to 1g of sorghum according to the ratio of material to liquid: 1:2;

[0090] The fourth step is to place the mixed solution in a beaker, and use an ultrasonic cleaner to perform ultrasonication in a water bath. The liquid level of the water bath exceeds the mixed liquid level. During the ultrasonic process, the stirrer stirs the mixed solution synchronously, and the power of the ultrasonic cleaner is set to 100w. , The temperature is set to 60°C, the stirring speed of the stirrer is 120r / min, and the ultrasonic and stirring time is 10min;

Abstract

The invention provides a sorghum dehulling method. The sorghum dehulling method comprises the steps of step I, adding water to soak sorghum to soften sorghum seed husks; step II, after soaking, filtering sorghum, and spin-drying filtered sorghum; step III, adding a soaking solution into the spin-dried sorghum; step IV, stirring a mixed solution of sorghum and the soaking solution, and carrying out ultrasonic treatment till the sorghum seed husks are separated; step V, removing the separated sorghum seed husks through filtration, and collecting sorghum grains; and step VI, spin-drying, cleaning and drying the collected sorghum grains, so as to obtain complete dehulled sorghum grains. The sorghum dehulling method has the beneficial effects that the sorghum dehulling efficiency is remarkably improved, the dehulling rate reaches 90% or above, the dehulled sorghum grains are complete, and loss of grains is reduced.

Description

technical field [0001] The invention relates to the field of peeling of seed coats, in particular to a method for peeling sorghum. Background technique [0002] Sorghum is one of the important cereal crops cultivated by humans, and it is the fifth largest cereal crop planted in the world after wheat, corn, rice, and barley. In recent years, with the enhancement of people's health awareness, more attention has been paid to the status and role of whole grains, and more pursuit of nutrition and functionalization of food. Studies have shown that sorghum has extremely high nutritional value. The slow-digesting starch and resistant starch in it can not only reduce the concentration of glucose in the blood, but also reduce the secretion of insulin. The synergistic effect of these two aspects can reduce the blood sugar index after eating. For diabetics, it can effectively control and relieve diabetes. However, the seed coat of sorghum contains a polyphenolic compound with an astri...
