Problems solved by technology

However, the traditional high-temperature steaming and frying and high-pressure pre-pressing oil production process have caused protein denaturation in cotton meal, and the nutritional value has been lost; and the content of toxic substances in cotton meal-gossypol is still high
At present, the production of cottonseed embryos is generally produced by ordinary shelling machines. The shell content, cashmere content, and impurities in the embryos are relatively large, which affects the normal operation of subsequent processes and the quality of cottonseed protein products.
In prior art 00134520.6, 200510017415.0, 200510124534.6, and 200710015284.1, the technical requirements for cottonseed embryos are disclosed, but the specific production method of cottonseed embryos and how to control the process parameters of cottonseed embryos are not given, and how to carry out continuous production is not involved industrial production

Embodiment 1

[0049] Such as figure 1 As shown, this embodiment provides a method for producing cottonseed embryos for low-temperature pretreatment to produce dephenolized cottonseed protein. The specific production steps are:

[0050]a. Use cottonseed with a water content of 9-13% and a cashmere content of 2-4%, and remove impurities by air selection, or use air selection and magnetic separation at the same time, so that the impurity content of cottonseed is ≤0.5%. Adjust so that only lint and impurities are blown out, and 2, 3, 4% are optional cottonseed lint content; too high or too low water content of raw cottonseed will affect the normal progress of subsequent processes, water content 9, 11, 13% are optional raw material cottonseed;

[0051] b. Input the cottonseed after removing impurities into the sheller for shelling treatment, and obtain the mixture of cottonseed hulls and cottonseed kernels. The feeding should be uniform and stable. Observe the material at the inlet and outlet o...

Embodiment 2

[0061] Such as figure 2 As shown, this embodiment provides a method for producing cottonseed embryos for low-temperature pretreatment to produce dephenolized cottonseed protein. The specific production steps are:

[0062] a. Use cottonseed with a water content of 7-16% and a velvet content of 2-6%, and remove impurities through winnowing, or winnowing and magnetic separation, so that the impurity content of cottonseed is ≤0.5%, and the air volume of winnowing is adjusted So that only lint and impurities are blown out, 2, 3, 4, 5, 6% are optional cottonseed velvet content; too high or too low moisture content of raw cottonseed will affect the normal progress of subsequent processes, moisture content 7 , 9, 11, 13, and 16% are all optional raw material cottonseed;

[0063] b. Input the cottonseed after removing impurities into the sheller for shelling treatment, and obtain the mixture of cottonseed hulls and cottonseed kernels. The feeding should be uniform and stable. Observe...

Embodiment 3

[0073] see image 3 , the present embodiment provides a method for producing cottonseed embryos for low-temperature pretreatment to produce dephenolized cottonseed protein, the specific steps of which are:

[0074] a. Use cottonseed with a water content of 7-16% and a velvet content of 2-6%, and remove impurities through winnowing, or winnowing and magnetic separation, so that the impurity content of cottonseed is ≤0.5%, and the air volume of winnowing Adjust so that only lint and impurities are blown out, 2, 3, 4, 5, 6% are optional cottonseed velvet content; too high or too low moisture content of raw cottonseed will affect the normal progress of subsequent processes, moisture content 7, 9, 11, 13, 16% are all optional raw material cottonseed;

[0075] b. Input the cottonseed after removing impurities into the sheller for shelling treatment, and obtain the mixture of cottonseed hulls and cottonseed kernels. The feeding should be uniform and stable. Observe the material at t...

Abstract

The invention provides a method for producing cottonseed germ materials used in low-temperature pretreatment production of gossypol-removed cottonseed protein. The method comprises: cleaning and removing impurities in delinted cottonseeds; husking the cottonseeds after impurity removal; obtaining mixture of cottonseed kernels and cottonseed husks; repeatedly separating the mixture by use of a screening and / or winnowing method; obtaining the cottonseed kernels in which the content of the cottonseed husks is less than or equal to 18 percent; softening the cottonseed kernels at a temperature lower than or equal to 80 DEG C; rolling the cottonseed kernels into germ sheets; adjusting quality at a temperature lower than or equal to 80 DEG C; and obtaining germ materials. The germ materials produced by use of the method have the advantages of good shape, high strength, less breakable property, good permeability during extraction, short seepage time, low content of residual oil and gossypol in meal after oil extraction and gossypol removal, capability of continuous production and capability of maintaining the original nutritional value of protein.

Description

technical field [0001] The invention belongs to the technical field of plant protein production, in particular, the invention relates to a method for producing cottonseed embryos used for low-temperature pretreatment to produce dephenolized cottonseed protein. Background technique [0002] my country is a big cotton-producing country with abundant cottonseed resources, which are rich in protein. However, the traditional high-temperature steaming and frying and high-pressure pre-pressing oil production process have caused protein denaturation in cotton meal, and the nutritional value has been lost; and the content of toxic substance-gossypol in cotton meal is still high. At present, the production of cottonseed embryos is generally produced by ordinary shelling machines. The shell content, cashmere content, and impurities in the embryos are relatively large, which affects the normal operation of subsequent processes and the quality of cottonseed protein products. In prior ar...
