Abstract

The invention discloses a preparation method of navel orange peel essential oil microcapsules. The method comprises the following steps: (1) preparing beta-cyclodextrin water solution, dissolving beta-cyclodextrin into water to obtain the beta-cyclodextrin water solution; (2) preparing a navel orange peel essential oil solution, dissolving navel orange peel essential oil into an organic solvent to obtain the navel orange peel essential oil solution; (3) preparing the navel orange peel essential oil microcapsules: dropwise adding the navel orange peel essential oil solution obtained in the step (2) into the beta-cyclodextrin water solution obtained in the step (1), heating the mixed solution, and embedding under the conditions of keeping out of the sun and sealing; after a reaction is completed, putting reaction liquid into a refrigerator for refrigerating, carrying out vacuum filtration and drying to constant weight so as to obtain the navel orange peel essential oil microcapsules. The preparation method of the navel orange peel essential oil microcapsules has the advantages of being good in embedding effect, high in stability, good in economy, and the like.

Description

technical field [0001] The invention relates to the technical field of storage of natural plant essential oils, in particular to a preparation method of navel orange peel essential oil microcapsules. Background technique [0002] Navel oranges are abundant in Fuchuan County, Hezhou City, Guangxi, and their peels are the main by-products in the process of eating and processing. According to the investigation, the comprehensive utilization of navel orange peels in this area is less at present, and most of them are discarded as waste, which not only wastes precious resources, but also seriously pollutes the environment. A large number of studies at home and abroad have confirmed that citrus essential oil has the functions of calming the human central nervous system and reducing stress, and also has the functions of expectorant, cough, gastrointestinal peristalsis, analgesia, anti-inflammatory and antibacterial, and also has very obvious effects on beauty and health care .
