Abstract

The invention provides an alpinia katsumadai essential oil microemulsion and a preparation method thereof, and the preparation method comprises the following steps: (1) mixing sorbitan fatty acid ester and absolute ethyl alcohol to obtain a mixed surfactant A; tween 80 and absolute ethyl alcohol are mixed, and a mixed surfactant B is obtained; (2) oscillating and stirring the alpinia katsumadai essential oil while dropwise adding a surfactant A to obtain a primary alpinia katsumadai essential oil mixed oil phase; (3) dropwise adding a mixed surfactant B while shaking and stirring, and adding a mixed aqueous solution of hydrochloric acid and sodium chloride to obtain a katsumadai seed essential oil mixed oil phase; (4) adding water into the alpinia katsumadai essential oil mixed oil phase in a stirring state, mixing, and shearing at a high speed until the alpinia katsumadai essential oil mixed oil phase is clear or semitransparent to obtain the alpinia katsumadai essential oil micro-emulsion, the prepared alpinia katsumadai essential oil micro-emulsion has excellent oxidation resistance and high scavenging capacity on DPPH free radicals and ABTS +. Free radicals, and meanwhile, the stability of the alpinia katsumadai essential oil micro-emulsion is obviously improved, the particle size distribution is uniform, and the dispersity is good.

Description

technical field [0001] The invention relates to the technical field of plant essential oil processing, in particular to a cardamom essential oil microemulsion and a preparation method thereof. Background technique [0002] Microemulsions (MEs) are thermodynamically stable, transparent dispersion systems that automatically form from surfactants, oil, water (or brine), and cosurfactants. The dispersed phase particles in this type of dispersion system are much smaller than those of ordinary emulsions, generally between 10-100 nm, and are mainly divided into three categories: oil-in-water (O / W), bicontinuous and water-in-oil Type (W / O). The excellent properties of microemulsion make it widely used in food, chemical, pharmaceutical and other fields. Stabilizing ingredients resist the influence of the external environment, such as oxygen, light, heat, acid and alkali, etc., and prevent the quality of food from deteriorating during processing and preservation. [0003] In recent...
