Problems solved by technology

[0004] However, due to the high content of crude fiber, it affects the digestion of livestock, and the palatability is poor, and the nutrient utilization rate is very low
There are few studies on the protein extraction of caragana, which needs further processing and utilization

Embodiment Construction

[0032] The present invention will be further described with the following examples; the following examples are illustrative and not restrictive, and the scope of protection of the present invention cannot be limited by the following examples.

[0033] A method for extracting Caragana korshinskii protein, the steps are:

[0034] (1) Coarse pulverization: dry the sorted and harvested summer flowering korshinskii to form dried korshinskii flower leaves or twigs, then knead it with a pulverizer and pulverize into filamentous materials with a length of 3 to 5 mm and a thickness of 0.5 to 1 mm for use;

[0035] (2) Washing and soaking: the filamentous raw materials are sent to the washing tank for washing to remove stolen goods and floating soil; the washing wastewater is separated from the solid and liquid by the omentum module, and the liquid enters the soaking tank to absorb water for the caragana, solid waste (sand, floating skin, etc.) After being separated and returning to the field,...

Abstract

The invention relates to an extraction method of caragana microphylla proteins, comprising the following steps of: preprocessing flowers and leaves or twigs of dry caragana microphylla; then washing; soaking; spirally conveying; carrying out extrusion cooking; carrying out mixed lixiviation; roughly filtering; finely filtering; flocculating; concentrating / separating; and drying so as to obtain the caragana microphylla proteins. The prepared caragana microphylla proteins have green color (as glycoprotein), extraction ratio of more than 80 percent and crude protein content of more than 90 percent, can not only be used as feeds, but also be used for industries, i.e. foods, pharmaceuticals, cosmetics, and the like, through further processing, and has very wide application prospect.

Description

Technical field [0001] The present invention belongs to the technical field of plant protein, and relates to extracting Caragana korshinskii protein by using dried Caragana korshinskii flower leaves or twigs as raw materials, in particular to an extraction method for Caragana korshinskii protein. Background technique [0002] Caragana korshinskii, Latin name: Caragana Korshinskii Kom, English name: Korshinsk Peashrub, also called wool-tiao, white korshinskii, is a large deciduous shrub forage plant of Caragana leguminosa. The root system is extremely developed, the main root is deep into the soil, and the plant height is 40. ~70 cm, the highest can reach about 2 meters, suitable for growing on sunny and semi-sun slopes at an altitude of 900 to 1300 meters, drought-tolerant, cold-tolerant, and high-temperature resistant. It is a xerophytic shrub in arid grasslands and desert grasslands. At present, Caragana korshinskii is one of the important tree species for water and soil conser...
