Abstract

The invention discloses a chitosan-galangal essence microcapsule which comprises a core material and a wall material, wherein galangal essence is taken as the core material, and the wall material is formed through complex coacervation of chitosan, polylysine and sodium caseinate; and the core material is covered inside the wall material. The invention further discloses a preparation method of the chitosan-galangal essence microcapsule and application of the microcapsule in a mosquito repellent and a textile antibiotic finishing agent. The chitosan-galangal essence microcapsule disclosed by the invention can be used for improving the light and heat stability of the galangal essence, and has the advantages of high intensity, good heat stability, long and lasting mosquito repelling and antibiotic effects, and the like.

Description

technical field [0001] The invention relates to a preservation technology of galangal essential oil, in particular to chitosan-galangal essential oil microcapsules. The invention also relates to a preparation method and application of chitosan-galangal essential oil microcapsules. Background technique [0002] Galangal (Alpinia 0fficinarum Hance) is the dry rhizome of galangal, a perennial herb of the Zingiberaceae genus Alpinia, which has various medicinal values. Galangal essential oil is a volatile oil extracted from the rhizome of Galangal ginger, which is transparent yellow and has a special ginger fragrance. Studies have shown that galangal essential oil has a significant repelling effect on mosquitoes, and has a strong inhibitory effect on sebaceous demodex and follicular demodex. kind of effect. The antibacterial properties of galangal essential oil can be applied to the development and production of natural antibacterial agents, and its insect repellent propertie...
