preparation example Construction

[0025] The present invention also provides a preparation method of the above-mentioned Eupatorium adenophorum essential oil microcapsules, comprising the following steps:

[0026] Dissolving the whey protein isolate to obtain the emulsifier aqueous phase;

[0027] Dissolving the diosgenin diosgenin to obtain the dioschina diosgenin solution;

[0028] mixing the essential oil of Eupatorium adenophorum and a cosolvent to obtain the capsule core oil phase;

[0029] performing the first homogenization of the capsule core oil phase and the emulsifier water phase to obtain a mixed emulsion;

[0030] The mixed emulsion is mixed with the yam polysaccharide solution, subjected to the second homogenization, and dried to obtain Eupatorium adenophorum essential oil microcapsules.

[0031] The invention dissolves the whey protein isolate to obtain the emulsifier water phase.

[0032] In the present invention, the reagent for dissolving the whey protein isolate preferably includes a buff...

Embodiment 1

[0058] Wash and dry the fresh underground tubers of yams, peeled and cut into 1cm 3 small pieces; reflux degreasing with 2.5 times the mass of petroleum ether for 5 hours, then suction filter and dry to obtain the filter residue; add 15 times the mass of deionized water to the filter residue, reflux hot water at 70°C for ultrasonic assisted extraction for 150 minutes, take the extract, and The obtained extract was concentrated under reduced pressure, and then 4 times the volume of absolute ethanol was added to the obtained concentrated solution, and left to stand overnight. After suction filtration, the obtained filter residue was washed 3 times successively with absolute ethanol, ether and acetone, and the obtained solid was in Freeze-dry at -80°C for 10 hours to obtain dioscin.

[0059] Fresh branches and leaves of Eupatorium adenophorum were crushed through a 20-mesh sieve to obtain powder of branches and leaves of Eupatorium adenophorum; then deionized water of 15 times th...

Embodiment 2

[0064] Wash and dry the fresh underground tubers of yams, peeled and cut into 1cm 3 Small piece;

[0065] Reflux and degrease with 2 times the mass of petroleum ether for 6 hours, then suction filter and dry to obtain the filter residue; add 10 times the mass of deionized water to the filter residue, reflux hot water at 60°C for 180 minutes with ultrasonic assisted extraction, take the extract, and extract the obtained extract Concentrate under reduced pressure, then add 4 times the volume of absolute ethanol to the obtained concentrated solution, let it stand overnight, and after suction filtration, wash the obtained filter residue three times with absolute ethanol, ether and acetone successively, and the obtained solid is stored at -80°C Freeze-dry for 10 hours to obtain yam polysaccharide.

[0066] Fresh branches and leaves of Eupatorium adenophorum were crushed through a 20-mesh sieve to obtain powder of branches and leaves of Eupatorium adenophorum; then, deionized water...

Abstract

The invention relates to the technical field of essential oil microcapsules, and provides an eupatorium adenophorum essential oil microcapsule, a preparation method thereof and an eupatorium adenophorum essential oil modified viscose fiber fabric. The eupatorium adenophorum essential oil microcapsule provided by the invention comprises a capsule wall and a capsule core, the capsule core comprises eupatorium adenophorum essential oil and a cosolvent; the capsule wall comprises whey protein isolate and yam polysaccharide. According to the present invention, the dioscorea alata polysaccharide mainly comprises glucose and mannose, the connection between the glucose and the mannose is mainly based on a beta-glucosidic bond, and a plurality of beta-1, 4-g mannose residues can form a spiral structure, such that the good embedding of the essential oil can be achieved by using the dioscorea alata polysaccharide as the wall material of the microcapsule; moreover, the dioscorea amabilis polysaccharide has good antibacterial performance, so that the microcapsule obtained by embedding the eupatorium adenophorum essential oil by taking the dioscorea amabilis polysaccharide as a wall material also has good antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of essential oil microcapsules, in particular to a microcapsule of Eupatorium adenophorum essential oil and a preparation method thereof, and viscose fiber textiles modified by Eupatoria adenophorum essential oil. Background technique [0002] Eupatorium adenophorum, also known as Jiefang grass, destroying grass, red deer grass, big black grass, etc., can extract volatile essential oils from the flowers and branches of Eupatorium adenophorum. The main components in the essential oil include sesquiterpenes, triterpenes, Monoterpenes, phenylpropanoids, flavonoids, steroids and various derivatives. It has been reported that Eupatorium adenophorum essential oil has different degrees of inhibitory effects on plant pathogens such as Fusarium oxysporum, Botrytis cinerea, Cercospora globus and Gibberella tritici. Pathogenic bacteria such as Staphylococcus aureus, Candida albicans and Escherichia coli also have diff...
