Embodiment 1

[0020] A method for extracting orange peel essential oil, comprising the following steps:

[0021] (1) Wash the fresh orange peel stems and leaves and soak them in water for 25 minutes, then put them into a sieve basket and immerse them in liquid nitrogen for 50 minutes, then lift them up and place them at room temperature for 8 minutes, then submerge the sieve baskets as a whole Put in liquid nitrogen for 50 minutes, repeat this process 3 times;

[0022] (2) Drying the orange peel in step (1) at low temperature, crushing, and passing through a 20-mesh sieve to obtain orange peel powder;

[0023] The low-temperature vacuum drying process is as follows: orange peels are stacked alternately in a vacuum drying oven, the vacuum degree is controlled to 0.009Mpa, the temperature of vacuum drying is 40°C, and the orange peels are dried until the water content is below 5%;

[0024] (3) Mix the orange peel powder with 0.05 times the weight of β-glucosidase and let it stand for 50 minu...

Abstract

The invention relates to a method for extracting essential oil from natural fruit orange peel, comprising the following steps: (1) cleaning fresh orange peel, soaking in water, putting into a sieve basket, integrally soaking in liquid nitrogen, and repeating for 2-3 times; (2) drying the orange peel in the step (1) at low temperature, and crushing to obtain orange peel powder; (3) extracting the orange peel powder by adopting a supercritical CO2 extraction method; and (4) enabling CO2 containing the extract to flow out of the extraction kettle and enter a separation kettle for reduced-pressureseparation to obtain the orange peel essential oil. According to the extraction method of the orange peel essential oil provided by the invention, the loss of effective components in the orange peelextraction process is avoided, and the quality and yield of the orange peel essential oil are improved.

Description

technical field [0001] The invention relates to a method for extracting natural plant essential oil, in particular to a method for extracting orange peel essential oil. Background technique [0002] Orange, also known as fragrant orange, is a small tree with oblate or pear-shaped fruit. The flowering period is April-May, and the fruiting period is October-November. Produced in many provinces and regions in China, not in the south of Wuling, it is a kind of citrus with a wider distribution and a northerner one. It is cold-tolerant, and some varieties are semi-deciduous. The orange fruit contains hesperidin, citric acid, malic acid, succinic acid, sugars, pectin and vitamin C that are beneficial to the human body; it is sweet in taste and flat in nature. It has the effects of promoting body fluid and quenching thirst, soothing the liver and regulating qi, and promoting milk. Orange peel contains valuable natural vitamin P and rich vitamin V and soluble cellulose. Vitamin P ...
