Problems solved by technology

In addition, the main components are polyunsaturated fatty acids of α-linolenic acid and linoleic acid, which have poor stability and will oxidize and deteriorate under the action of air or ultraviolet rays.

Embodiment Construction

[0011] The seeds (seeds) of Artemisia arvensis collected from the loess zone in Tianshui area, Gansu Province, are obtained by mechanical pressing. The obtained Artemisia persicae oil is light yellow and has a density of 886kg / m 3 . The fatty acid composition of the oil was analyzed by gas chromatography tandem mass spectrometry. The instrument used is a gas chromatography-mass spectrometer: Agilent Technologies Co., Ltd., 6890N-GC / 5973N-MSD (the following tests in the present invention all use this instrument). The fatty acid composition of Artemisia persicae oil was measured as follows:

[0012] Palmitic acid (5.57%), stearic acid (1.88%), linoleic acid (14.63%), α-linolenic acid 42.75%), arachidic acid (2.14.%), arachidic acid (15.05%), erucic acid (17.02.%) and so on.

[0013] Take 10ml of Artemisia annua oil, add methanol: 20ml and H 2 O: In 5ml, NaOH (solid): 1.2g was added thereto. Reflux under stirring conditions, during which the reaction temperature is controll...

Abstract

The invention discloses a removing method of erucic acid in the plant oil, which comprises the following steps: picking the seed of wormwood; removing impurity; dehydrating; squeezing; separating solid from liquid; obtaining the oil; adopting carbinol as solvent to do saponifying hydrolysis under alkaline condition; stewing; laminating; separating the composite fatty acid on the upper layer from the water layer on the lower layer; dissolving the composite fatty acid in the carbinol fitfully; placing the composition in the refrigerator until crystallizing and evolving; sucking in the vacuum; adding water in the filtrate to reextracte; obtaining the multiple unsaturated fatty acid with alpha-linolenic acid, linolic acid, arachidonic acid and less than 2% erucic acid.

Description

technical field [0001] The present invention relates to a method for removing erucic acid from vegetable oil, in particular to a method for removing erucic acid from the oil obtained from the plant Artemisia indica, especially the oil obtained from the seeds of Artemisia indica. Background technique [0002] Artemisia sophia is a wild plant of the genus Artemisia cruciferae. Its scientific name is Descurainia Sophia (L.) Webb ex Prantl. It is widely distributed in the Loess Plateau and Qinghai-Tibet Plateau in my country. It has strong adaptability, cold resistance and drought resistance. , and cattle and sheep do not eat. Chinese invention patent 99114958.0 discloses a method for isolating special oil from the seeds of Artemisia indica plant. The method is to harvest the seeds of Artemisia sobani, and obtain the oil through solid-liquid separation processes such as cleaning, dehydration, extrusion or leaching, and then carry out deslagging, clarification and anti-oxidation ...
