Abstract

The invention discloses a navel orange peel essential oil extracting method, which comprises the following steps: (1) crude navel orange peel essential oil preparation: smashing navel orange peel, putting into an extraction kettle of a microwave-ultrasonic wave synergistic extractor, adding an extracting solvent to perform microwave-ultrasonic wave synergistic extraction, filtering extract liquor and rectifying filtrate to obtain crude navel orange peel essential oil; (2) terpene removing 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 molecular distillation apparatus, performing molecular distillation and collecting distillation residues to obtain navel orange peel essential oil. The navel orange peel essential oil extracting method has the advantages of quickness, high efficiency, high yield, high 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 tribute mandarin orange and navel orange peels in this area is seldom 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 central nervous system and reducing stress, and also has the functions of expectorant, cough, gastrointestinal peristalsis, analgesia, anti-inflammatory and antibacterial, etc. At the same time, essential oil also has obvious ef...
