Embodiment 1

[0036] A preparation method of quinoa protein, comprising the following steps:

[0037] Step 1: Quinoa Pretreatment

[0038] Rinse the quinoa continuously with pure water, drain the water, soak it in hot water for 5 hours, dry it in an oven, add ethanol and mix well, then put it into a grinder for grinding. The ratio of quinoa to ethanol is 1:5 ;

[0039] Step 2: Enzymolysis

[0040]Use sodium hydroxide to adjust PH=9.5-10.5, add 8% alkaline protease to the quinoa protein slurry for hydrolysis, keep warm at 30-35°C for 2 hours, and initially obtain the quinoa protein slurry, and then use dilute acetic acid to adjust the pH to 6.5-7.5 Add 8% amylase and digestive enzymes, the mass ratio of amylase and digestive enzymes is 1:1, keep warm at 30-35°C, fully react for 2 hours, and spray-dry the obtained protein solution to obtain high purity Quinoa protein powder.

[0041] Step 3: Cross-linking modification

[0042] Mix quinoa protein powder with ethanol at a ratio of 1:5, and...

Embodiment 2

[0054] A preparation method of quinoa protein, comprising the following steps:

[0055] Step 1: Quinoa Pretreatment

[0056] Rinse the quinoa continuously with pure water, drain the water, then soak it in hot water for 3 hours, dry it in an oven, add ethanol and mix well, put it into a grinder for grinding, the ratio of quinoa and ethanol is 1:5 ;

[0057] Step 2: Enzymolysis

[0058] Use sodium hydroxide to adjust PH=9.5, add 0.05 alkaline protease of quinoa protein slurry to hydrolyze, keep warm at 30-35°C, initially obtain quinoa protein slurry, then adjust PH to 6.5-7.5 with dilute acetic acid, add amylase and digestive enzymes, keep warm at 30-35°C, fully react for 3 hours, and spray-dry the obtained protein solution to obtain high-purity quinoa protein powder.

[0059] Step 3: Cross-linking modification

[0060] Mix quinoa protein powder with ethanol at a ratio of 1:5, and fully dissolve with 0.8% sodium hydroxide solution. The specific dissolution temperature curve ...

Abstract

The invention discloses quinoa protein liquid for fiber compounding and a preparation method of quinoa protein fibers, and solves the technical problems that existing quinoa protein extraction and modification methods are not suitable for being combined with regenerated cellulose fibers and does not have a quinoa protein fiber composite material. The method comprises the following steps: modifying quinoa protein liquid by adopting sodium hexadecyl sulfonate and trimethylolpropane trimethacrylate in sequence to obtain modified quinoa protein liquid. The extracted quinoa protein is suitable for being compounded with cellulose fibers in terms of content and purity, and the obtained quinoa protein composite fibers have the advantages of being high in protein content, high in breaking strength and the like.

Description

technical field [0001] The invention relates to the technical field of functional cellulose fibers, in particular to a preparation method of quinoa protein liquid and quinoa protein fibers. Background technique [0002] Quinoa is a plant in the Chenopodium family. The spikes can be red, purple, or yellow, and the shape of the plant is similar to that of ashweed, and the spikes are similar to sorghum spikes after maturity. Native to Colombia, Ecuador, and Peru in the Andes of South America. It has certain drought tolerance, cold tolerance and salt tolerance. Quinoa is rich in vitamins, polyphenols, flavonoids, saponins and phytosterols with various health benefits. Quinoa has high protein, and the main components of quinoa protein are albumin and globulin, and the effect of disulfide bonds makes their molecular structure more stable. Quinoa protein is a kind of whole protein food, which contains almost all natural amino acids, especially rich in 8 amino acids necessary fo...
