Abstract

The invention discloses a litsea cubeba oil microcapsule and a preparation method thereof, and belongs to the technical field of mouldproof and insecticidal capsules. The litsea cubeba oil microcapsule is characterized by being prepared by the complex coacervation of litsea cubeba oil taken as a core material, sodium alginate taken as a main wall material and an aqueous solution which contains 1% to 5% of chitosan and 2% to 5% of anhydrous calcium chloride and is taken as a coagulating bath solution, wherein the mass ratio of the sodium alginate to the litsea cubeba oil is 1:(1-4). The preparation method mainly comprises the following steps: firstly preparing an emulsion A of the sodium alginate and the litsea cubeba oil; then preparing the aqueous solution of the chitosan and the anhydrous calcium chloride as the coagulating bath solution B; dripping the emulsion A into the coagulating bath solution B; and solidifying the mixture for certain time and then filtering the mixture, thereby obtaining the litsea cubeba oil microcapsule. Thus, the litsea cubeba oil microcapsule which is high in litsea cubeba oil content, long in service time and good in mouldproof and insecticidal effect and the preparation method of the litsea cubeba oil microcapsule are provided. The litsea cubeba oil microcapsule is mainly used for performing mouldproof and insecticidal functions on grains as well as on clothes.
