Embodiment 1

[0019] Weigh the wall material gum arabic and maltodextrin in a ratio of 1:5 by weight, add water twice the mass of the wall material to dissolve, and stir evenly to obtain a wall material solution; add 10% of the core material Cyperus volatile oil Into the wall material solution, mix evenly to obtain a dispersion; add a mixed emulsification mixture of 1% monoglyceride and Tween 40 (the mass ratio of monoglyceride to Tween 40) to the dispersion using high-pressure homogenizing equipment to homogenize the dispersion after adding the emulsifier at a temperature of 60 ° C and a pressure of 10 MPa twice, each time for 6 minutes, to obtain an emulsion; put the homogenized emulsion into 4 After refrigerated in a refrigerator at ℃ for 24 hours, filter with medium-speed filter paper at a vacuum degree of 0.08MPa and a temperature of 25°C to obtain a filter cake; dry the obtained filter cake at a vacuum degree of less than 20Pa and a cold trap temperature of -40°C to obtain Cyperus vol...

Embodiment 2

[0021] Weigh the wall material gum arabic and maltodextrin in a ratio of 1:10 by weight, add 4 times the weight of the wall material to dissolve in water, stir evenly, and obtain the wall material solution; add 30% of the core material Cyperus volatile oil Into the wall material solution, mix evenly to obtain a dispersion; add a mixed emulsification mixture of 2% of the wall material mass monoglyceride and Tween 40 (the mass ratio of monoglyceride to Tween 40 is 3:1) to the dispersion agent; use high-pressure homogenization equipment to homogenize the dispersion after adding the emulsifier at a temperature of 90 ° C and a pressure of 25 MPa twice, each time for 6 minutes, to obtain an emulsion; put the homogenized emulsion into 0 After refrigerated in a refrigerator at ℃ for 24 hours, filter with medium-speed filter paper at a vacuum degree of 0.10 MPa and a temperature of 10 °C to obtain a filter cake; dry the obtained filter cake at a vacuum degree of less than 20 Pa and a co...

Embodiment 3

[0023] Weigh the wall material gum arabic and maltodextrin in a ratio of 1:7 by weight, add 3 times the weight of the wall material to dissolve in water, stir evenly, and obtain the wall material solution; add 20% of the core material Cyperus cyperi Into the wall material solution, mix evenly to obtain a dispersion; add 1.5% wall material mass of monoglyceride and Tween 40 (the mass ratio of monoglyceride to Tween 40 is 3:1) to the dispersion using high-pressure homogenizing equipment to homogenize the dispersion after adding the emulsifier at a temperature of 70°C and a pressure of 20 MPa twice, each time for 6 minutes, to obtain an emulsion; put the homogenized emulsion into 2 After refrigerating in a refrigerator at ℃ for 24 hours, filter with medium-speed filter paper at a vacuum degree of 0.10 MPa and a temperature of 15 °C to obtain a filter cake; dry the obtained filter cake at a vacuum degree of less than 20 Pa and a cold trap temperature of -50 °C to obtain Cyperus vo...

Abstract

The invention relates to a preparation method of rhizoma cyperi volatile oil microcapsules. The preparation method comprises the following processing steps: preparing a wall material solution by taking Arabic gum and maltodextrin as raw materials; then, adding a core material rhizoma cyperi volatile oil and uniformly dispersing, thus obtaining dispersion liquid; adding a mixed emulsifier of monostearin and tween 40, mixing and homogenizing, thus obtaining an emulsion; and carrying out refrigeration, suction filtration and freeze drying on the emulsion, thus obtaining a rhizoma cyperi volatile oil microcapsule product. The method disclosed by the invention is simple and practical in process, and preparation conditions are easily controlled; volatile oil can be separated from outside air, so that the situation that the volatile oil volatilizes when stored for a long time is avoided; therefore, the storage time of the rhizoma cyperi volatile oil can be effectively prolonged.

Description

technical field [0001] The invention relates to a preparation method of Cyperus cyperi volatile oil microcapsules, belonging to the technical field of microcapsules. Background technique [0002] Cyperus Cyperi, also known as Cyperus Cyperi, Jinxiangfu, and Dongxiangfu, is the dry rhizome of Cyperaceae Cyperus cyperus. Flat in nature, pungent in taste, slightly bitter and slightly sweet, has the effects of promoting qi and relieving depression, regulating menstruation and relieving pain. The main medicinal ingredients in Rhizoma Cyperus are volatile oils, which include cyperene, cyperene, α - Cyperone, β -Cyperone and other ingredients can be used in medicine and health care products and other industries. [0003] The main components of the volatile oil of Cyperus cyperi are mostly heat-unstable components and have peculiar smell, which will be volatilized and lost with the prolongation of storage time. After treatment with microcapsule technology, it can prevent the vol...
