Gastrodia elata wine and preparation method thereof

The invention discloses a preparation method of gastrodia elata wine. The method comprises the following steps: crushing gastrodia elata, adding active dry yeast of glucose and distilled water, fermenting, filtering and distilling filtrate at reduced pressure to obtain distillate B; filtering residual mother liquor by an ultrafiltration membrane to obtain filtrate C; taking 10-12 parts by volume of white spirit, 0.5-1 part by volume of distillate and 1-1.5 parts by volume of filtrate; evenly mixing, placing at room temperature for 24 hours; and filtering by the ultrafiltration membrane to obtain the filtrate, namely the gastrodia elata wine. Compared with the prior art, the method has the advantages that gastrodia elata wine mash is prepared by adopting a biological enzymatic transformation method; and a little gastrodia elata wine mash and the white spirit are blended, so as to obtain the transparent gastrodia elata wine with good taste, mellow flavor and certain health-care function. An experiment proves that the gastrodia elata wine has significant effects of easing pain and calming mind, and can effectively promote sleeping quality. Furthermore, the gastrodia elata wine disclosed by the invention is reasonable in preparation method, simple to operate, and low in production cost; the content of chemical ingredients of the gastrodia elata in the blended wine is low, so that the administration dose is not limited; and the gastrodia elata wine can be taken everyday.

Method for removing acrylonitrile monomer in spinning solution

The invention relates to a method for removing an acrylonitrile monomer in a spinning solution, which mainly solves the problem that in the prior art, a solvent is easy to take out together and the surface of the spinning solution is easy to crust in a process of striping the acrylonitrile monomer in the spinning solution. The method comprises the following steps of: placing a copolymer and the spinning solution of an initiator in a container, wherein the copolymer is obtained through the copolymerization between one solvent acrylonitrile monomer containing at least one of dimethylsulfoxide, dimethylformamide and dimethylacetamide and an acrylonitrile monomer, and the initiator initiates the copolymerization of the monomers; vacuumizing the container to a vacuum degree of 5 to 500mbar; b. in the mixing state, injecting gas into the container so as to lead the pressure of the container to restore to the constant pressure, wherein the gas is inert relative to the spinning solution; and c. repeating the steps from a to b so as to ensure that the residual amount of the acrylonitrile monomer in the spinning solution is less than 0.1%. The technical scheme better solves the problem and can be applied to the industrial production of removing the acrylonitrile monomer in a solution spinning process.

Preparation method and application of blueberry anthocyanin chitosan nanoemulsion

The invention provides a preparation method and application of a blueberry anthocyanin chitosan nanoemulsion, and belongs to the field of nanotechnology. The preparation method comprises the following steps: ultrasonically extracting blueberry pomace to obtain a blueberry anthocyanin extracting solvent; freeze-drying; adding a blueberry anthocyanin crude extract to a chitosan hydrochloride solvent with a concentration of 0.5-0.8mg / mL to obtain a mixed solvent I; dropwise adding a carboxymethyl chitosan solvent with the pH of 6.0 plus or minus 0.1 and a concentration of 0.5-2.0mg / mL to the mixed solvent I to obtain a blueberry anthocyanin chitosan nanoemulsion. The blueberry anthocyanin chitosan nanoemulsion prepared by the method can be used for preparing an eye drop and a blueberry anthocyanin beverage. The preparation method provided by the invention is simple, and the average particle size of the prepared blueberry anthocyanin chitosan nanoemulsion is less than 500nm; meanwhile, the loss rate of anthocyanin in the blueberry anthocyanin chitosan nanoemulsion prepared by the invention is extremely small as the storage time prolongs, and the prepared eye drop and beverage have the characteristics of high anthocyanin content, stable property and the like.
