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
The present invention relates to a kind of preparation method of Rhizoma Cyperi volatile oil microcapsule, belong to microcapsulary field.
Background technology
Rhizoma cyperi, has another name called Rhizoma Cyperi, cyperi rhizoma, eastern rhizoma cyperi, is the dry rhizome of sedge nutgrass flatsedge.Property is put down, and pungent, the micro-hardship of taste is micro-sweet, has the effect of promoting qi circulation and removing obstruction in the collateral, menstruction regulating and pain relieving.Main pharmacodynamics composition in rhizoma cyperi is volatile oil, it comprise cyperene, cyperol,
α-cyperone,
βthe compositions such as-cyperone, can be used for the industries such as medicine and healthcare products.
The main component of Rhizoma Cyperi volatile oil is mostly thermally labile component, and has peculiar smell, the volatilization loss along with the prolongation of waiting time.After adopting microcapsulary to process, can prevent the volatilization of volatile oil, increase its stability, also can cover the peculiar smell of volatile oil.
Microcapsulary is a kind of technology of formation fine particle that solid or liquid is coated with film forming material, and this technology, through the development of decades, reaches its maturity.The diameter of microcapsule is generally 2 ~ 1000 μ m, and wall thickness is 0.2 ~ 10 μ m, and along with the development of technology, size prepares at the Nano capsule of 1 ~ 1000nm.After product micro encapsulation, can realize many objects: improve the physical properties (color, outward appearance, solvability) that is wrapped material, make material avoid the impact of environment, improve the stability of material, shielding taste and smell, control the release of material etc. as required.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of rhizoma cyperi microcapsule, present method can prevent the volatilization of volatile oil, increases its stability, also can cover the peculiar smell of volatile oil.
The present invention is achieved by following technical solution:
A. wall material gum arabic and maltodextrin are dissolved in water by weight 1:5 ~ 10, stir, obtain wall material solution, standby;
B. get the core Rhizoma Cyperi volatile oil of wall material amount 10 ~ 30%, join in wall material solution, mix, obtain dispersion liquid;
C. in dispersion liquid, add the Tegin 55G of wall material amount 1 ~ 2% and the blending emulsifiers of polysorbate40, merge homogeneous and obtain milk sap;
D. the milk sap after homogenizing is put into 0 ~ 4 ℃ of refrigerator and cooled and hidden after 24h, under vacuum tightness 0.08MPa ~ 0.10MPa and 10 ~ 25 ℃ of conditions of temperature, adopt Medium speed filter paper to filter, obtain filter cake;
E. the filter cake of gained in steps d is less than under 20Pa, condenser temperature-40 ~-70 ℃ condition and is dried in vacuum tightness, obtain Rhizoma Cyperi volatile oil microcapsule product.
The add-on of the water described in step a is 2 ~ 4 times of wall material amount.
The weight ratio of the Tegin 55G described in step c and polysorbate40 is 3:1.
Homogeneous described in step c is that to adopt high-pressure homogeneous equipment be homogeneous twice under 60 ~ 90 ℃, the condition of pressure 10 ~ 25MPa by adding dispersion liquid after emulsifying agent in temperature, each 6min.
Beneficial effect of the present invention is: adopt micro-encapsulation technology to process Rhizoma Cyperi volatile oil, do not change the chemical structure of volatile oil, improve stability and the dissolution dispersity of volatile oil, effectively extend the shelf time of Rhizoma Cyperi volatile oil, the peculiar smell of shielding volatile oil.
