Abstract

The invention relates to a preparation method of a carex meyeriana volatile oil microcapsule and relates to the technical field of microcapsule preparation. The preparation method comprises the operation steps of pretreatment, distillation, extraction, emulsification and granulation. By using the preparation method of the carex meyeriana volatile oil microcapsule, the prepared microcapsule has smaller particle size, the average particle diameter is 3.5 microns, and particle size distribution is more uniform. Then, staphylococcus aureus and escherichia coli are inhibited by adding the carex meyeriana volatile oil microcapsule and sodium benzoate which are equal in adding amount, its bacteriostasis rate is slightly lower than that of the sodium benzoate. However, the sodium benzoate is a chemical agent, its food safety is poorer than that of the carex meyeriana volatile oil microcapsule and the carex meyeriana volatile oil microcapsule has good continuity and meanwhile has better fragrance, so that the carex meyeriana volatile oil microcapsule has a wider application prospect.

Description

Technical field: [0001] The invention relates to the technical field of preparation of microcapsules, in particular to a preparation method of microcapsules of essential oil of Uralia sativa. Background technique: [0002] Ulagrass, also known as sedge, is a plant of the Cyperaceae Carex genus, which mainly grows in the Changbai Mountains and the south of the Outer Xing'an Mountains in Northeast China. Ulagrass has the main functions of deodorizing, clearing the meridians, relieving fatigue, improving blood microcirculation, improving immunity, and inhibiting bacteria. Its main active ingredient is the volatile oil contained in Uralia sativa, which has a fresh smell, but due to its good volatility, the smell is emitted quickly and has poor persistence. At present, there are many studies on the volatile oil of Uralia sativa, but there are few researches on making the volatile oil of Urassica sativa into microcapsules. Due to the different components, the process and packagi...
