Problems solved by technology

The mechanical pressing method has long pressing time, low oil yield, high impurity content, poor oil quality, and darker color; the organic solvent extraction method has long extraction time, low efficiency, large solvent consumption, and easy to cause solvent residue in the product and a series of disadvantages; while supercritical fluid extraction has high requirements for equipment, complex process, small equipment volume, high cost, and high energy consumption, so it is not suitable for large-scale industrial continuous production

Embodiment 1

[0022] Embodiment 1 A kind of subcritical fluid extracts the method for seabuckthorn seed oil, comprises the following steps:

[0023] (1) The seeds obtained after juicing fresh and clean seabuckthorn fruits are dried in the shade at room temperature, sorted, crushed, and passed through a 10-mesh sieve to obtain seabuckthorn seed raw materials.

[0024] (2) Rolling the seabuckthorn seed raw material at 20° C. for 60 minutes and then drying for 8 hours to obtain treated seabuckthorn seeds.

[0025] (3) The processed seabuckthorn seeds and the extractant—propane are put into the extraction kettle of the subcritical fluid extraction device at a mass-volume ratio (g / mL) of 1:1. Under the conditions of 0.15MPa and extractant flow rate of 10L / h, extract continuously once, each time for 10min, to obtain the extract.

[0026] (4) Using the method of decompression and heating, the extract is separated under the conditions of separation pressure of 0.10 MPa and separation temperature o...

Abstract

The invention relates to a method for extracting sea buckthorn seed oil through a subcritical fluid method. The method for extracting the sea buckthorn seed oil comprises the following steps: (1), juicing fresh clean sea buckthorn fruit to obtain seeds, drying the seeds in shade under a room temperature, selecting the seeds, smashing the selected seeds, and screening the smashed seeds to obtain a raw sea buckthorn seed material; (2), grinding and drying the raw sea buckthorn seed material; (3), putting the ground dry sea buckthorn seeds and an extracting agent into a subcritical fluid extraction device, so as to obtain an extract; and (4), separating the extract through a pressure reducing and temperature increasing method to obtain an extraction liquid, and standing the extraction liquid under the room temperature to obtain the sea buckthorn seed oil. The method has the advantages that the production cost is effectively reduced; the separation time is shortened; the solvent consumption and the energy consumption in the technological process are reduced; the technological process is simple; the operability is high; the extraction efficiency is high; environmental protection and zero contamination are realized; the security and the repeatability are good; and large-scale industrialized continuous production can be realized.

Description

technical field [0001] The invention relates to the technical field of vegetable oil extraction, in particular to a method for extracting seabuckthorn seed oil with a subcritical fluid. Background technique [0002] Hippophae rhamnoides L. is the dry mature seed of Hippophae rhamnoides L. Seabuckthorn originated from the Qinghai-Tibet Plateau of my country and is mainly distributed in the Northwest and Northeast of China. Seabuckthorn seed oil is a high value-added product, rich in a variety of biologically active substances, such as vitamin E, carotenoids, unsaturated fatty acids, flavonoids, amino acids and trace elements, etc., anti-aging, anti-tumor, anti-radiation damage, It has obvious pharmacological effects on cardiovascular and cerebrovascular system, body immunity, etc. It is a kind of natural antioxidant and precious medicinal oil in modern medicine (Yu Changqing, Yang Huiwen. The characteristics of seabuckthorn oil and supercritical CO 2 Extraction process [J]....
