Embodiment 1

[0024] A kind of extraction method of navel orange pericarp essential oil of the present invention, comprises the following steps:

[0025] (1) Preparation of crude navel orange peel essential oil:

[0026] (1.1) After pulverizing 200 g of navel orange peel preserved in a cold storage at -18°C through a high-speed traditional Chinese medicine pulverizer, the mass volume ratio of the crushed navel orange peel and distilled water is 1g: 10mL and mixed in the mixed solution. It is the compound enzyme that is made up of pectinase and cellulase of 0.5% of navel orange peel quality, wherein, the mass ratio of pectinase and cellulase is 5: 1, and the enzyme activity of pectinase is 60000U / g, fiber The enzyme activity of the enzyme is 60000U / g. Then place it in a water bath environment at 45° C. for enzymatic hydrolysis for 1 hour, and obtain an enzymatic hydrolysis mixture after cooling.

Abstract

The invention discloses an extraction method of navel orange peel essential oil. The extraction method comprises the following steps: (1) preparation of crude navel orange peel essential oil: crushing navel orange peels, mixing with water, carrying out enzymolysis by virtue of compound enzyme formed by pectinase and cellulase so as to obtain enzymolysis mixed liquid, carrying out enzyme deactivation on the enzymolysis mixed liquid, extracting essential oil by virtue of microwave-assisted supercritical CO2 fluid extracting instrument, injecting extracting liquid into a separator to separate CO2, and rectifying a separated product, so as to obtain the crude navel orange peel essential oil; and (2) terpene removal treatment of the crude navel orange peel essential oil: putting the crude navel orange peel essential oil obtained in the step (1) into a reaction kettle of a molecular distillation instrument, carrying out molecular distillation, and collecting a distillation residue, so as to obtain the navel orange peel essential oil. The extraction method of the navel orange peel essential oil has the advantages of rapidness, high efficiency, yield and essential oil content, stable quality and the like.

Description

technical field [0001] The invention relates to the technical field of extracting natural plant essential oils, in particular to a method for extracting navel orange peel essential oils. 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 motility, analgesia, anti-inflammatory and antibacterial effects. effect. The world's annual output of citrus essential oil is about 26,000...
