B, it distills: sedge powder made from a step is mixed with water, the mass ratio of sedge powder and water is 1:5~10, leaching
1h is steeped, 10~15h of continuous still obtains fraction；
C, it extracts: fraction made from b step being mixed with extract liquor, mass ratio 5:1~3 of extract liquor and sedge powder are gone
Except extract liquor, volatile oil is obtained；
D, it emulsifies: adding dehydrated alcohol to dissolve volatile oil made from step c, water and emulsifier is added, packet is added in homogeneous 5min
The mass ratio of material, packaging material and volatile oil is 1:8~10, and 45 DEG C of constant temperature stir 2h, emulsion is made；
E, pelletize: by emulsion made from Step d, for 24 hours, centrifugation takes particle to constant temperature at 4 DEG C, low-temperature vacuum drying to get at
Product.
As a further improvement of the present invention, packaging material described in the Step d is cyclodextrin aqueous solution, cyclodextrin and water
Mass ratio is 1:6.
As a further improvement of the present invention, the emulsifier in Step d is sorbitan monostearate, diacetyl tartaric
One of sour monoglyceride, sucrose fatty ester, distillation monoglyceride or more than one arbitrary proportion combination.
As a further improvement of the present invention, extract liquor described in step c is chloroform or ether.
As a further improvement of the present invention, in step c the mass ratio of extract liquor and sedge powder be 5:1 or 5:2 or
5:3。
As a further improvement of the present invention, the mass ratio of packaging material and volatile oil is 1:8 or 1:9 or 1:10 in Step d.
The sedge that the present invention uses originates from Qiqihar.
Using a kind of preparation method of sedge volatile oil microcapsule of the invention, the microcapsules finished product grain size of preparation compared with
Small, average grain diameter is 3.5 μm, and particle diameter distribution is more uniform.Sedge volatile oil microcapsule and sodium benzoate suppression are added in equivalent
Staphylococcus aureus and Escherichia coli processed, bacteriostasis rate is slightly below sodium benzoate, but sodium benzoate is chemical reagent, food
Product safety is poor compared with sedge volatile oil microcapsule, and the duration of sedge volatile oil microcapsule is good, while having preferably
Fragrance, therefore have more application prospect.
