Abstract
The present invention discloses supercritical propane fluid process of extracting the active component from wolfberry seed, and belongs to the field of the vegetable oil extracting technology. Wolfberry seed separated from fresh wolfberry fruit after being dried and crushed is set inside supercritical extracting reactor, and supercritical propane fluid is introduced, so as to extract under certain supercritical pressure and temperature for certain time. The wolfberry seed oil is separated in a separating reactor. The present invention has short extraction time, high product yield and no propane residue. The wolfberry seed oil has certain effect of preventing and assisting the treatment of cardiac and cerebral vascular diseases, diabetes, hypertension, etc. and raising immunity.
Description
Technical field
The invention belongs to the vegetable oil extraction technical scope, particularly a kind of method that adopts activeconstituents in the supercritical propane fluid extraction matrimony vine seed.
Background technology
The mature fruit of Lycium Solanaceae machaka is the traditional Chinese medicinal materials of China, and the beginning is stated from " legendary god of farming's grass warp ".Compendium of Material Medica is stated " matrimony vine is obeyed for a long time, mends the vital essence deficiency, and easily appearance bleaches, and makes eye bright and calms the nerves, and makes us long-lived ".Seed accounts for 15-20% in the matrimony vine, and oil-containing about 18% in the matrimony vine seed.As the sexual propagation organ of matrimony vine, contain the effective biologically active substance that does not have in a large amount of pulp in the matrimony vine seed.Boxthorn Seed Oil contains a large amount of unsaturated fatty acidss, and wherein linolic acid is 68.3%, and gamma linolenic acid is 2.8%, and oleic acid is 19.1%, and vitamin-E is 271.4 μ g/g.These materials have reducing cholesterol, prevent hyperlipidemia and arteriosclerosis, delaying decrepitude of skin, beauty care and the effect of brightening, in addition, linolic acid also is of value to infant's heart and brain and histiocytic growing, therefore, it is a kind of good health care edible oil.China have abundant matrimony vine resource, especially lycium barbarum with its unique improved seeds and widely purposes and health-care effect be subjected to domestic and international personage's favor deeply, therefore, development and use matrimony vine resource has vast market prospect.
At present, hydrodistillation, direct expression, organic solvent extractionprocess are generally adopted in the extraction of Boxthorn Seed Oil.Because matrimony vine oil is fixed oil, it can not steam with water vapour, so hydrodistillation extraction matrimony vine oil yield is lower; And no matter direct expression is to adopt cold press or hot moulding because the matrimony vine seed is harder, and its oil yield is all very low; For solvent extration, the quality product of its extraction is relatively poor, and purity is low, and peculiar smell and dissolvent residual are arranged, and this has had a strong impact on its promotion and application.
In recent years, supercritical fluid technology is widely used in fields such as medicine, biology, food, makeup, oil, chemical industry, environmental protection with its unique advantage.Supercritical fluid extraction is based on extracting power and the selectivity of a kind of solvent to solid and liquid as a kind of development and application of sepn process, under supercritical state than under normal temperature and normal pressure, obtaining great raising.It is to utilize supercutical fluid, be that temperature and pressure surpasses or near critical temperature and emergent pressure, fluid between gas and liquid, as extraction agent, from solid or liquid, extract certain high boiling point or thermo-sensitivity composition, to reach the purpose of separation and purifying.At present, supercritical CO

2Extract the method for Boxthorn Seed Oil, but extraction yield needs still further to improve.In order to shorten extraction time, further improve the yield of Boxthorn Seed Oil, simultaneously also in order to explore and to enlarge the application of other supercutical fluid in the Boxthorn Seed Oil leaching process, the present invention adopts supercritical propane fluid extraction Boxthorn Seed Oil.Utilize supercritical propane fluid extraction Boxthorn Seed Oil not see document and patent report as yet at present.
Summary of the invention
The purpose of this invention is to provide by the activeconstituents in the supercritical propane fluid extraction matrimony vine seed, improve the yield of Boxthorn Seed Oil, shorten a kind of method of extracting activeconstituents in the matrimony vine seed of extraction time.It is characterized in that:
The method of activeconstituents is to adopt supercritical propane fluid extraction technology in the described extraction matrimony vine seed, and its extraction step comprises:
(1) obtain the matrimony vine seed after new fresh fructus lycii pulping separates, matrimony vine seed drying is put into extraction kettle after pulverizing.
(2) extraction kettle pressure is 5-15MPa, and temperature is 97-110 ℃, and the extraction time is 60-250 minute.
(3) extraction-container pressure is 1.0-2.0MPa, and temperature is 90-105 ℃.
(4) flow of propane is 3.0-7.0kg/hr.
(5) yield of Boxthorn Seed Oil is not less than 17%.
The invention has the beneficial effects as follows and utilize propane under postcritical state, to have good penetration and dissolving power,, reach a kind of method that improves the Boxthorn Seed Oil extraction yield by parameters such as control supercritical propane fluidic pressure, temperature, times.This method operating process is simple, be easy in control, extraction time weak point, oily yield height, the product no propane residual, have a favorable industrial application prospect.
Embodiment:
The invention provides a kind of method of extracting activeconstituents in the matrimony vine seed.Its principle is based on extracting power and the selectivity of a kind of solvent to solid and liquid, under supercritical state than under normal temperature and condition of normal pressure, obtaining great raising.It is to utilize the supercritical propane fluid as extraction agent, by control supercritical pressure and parameters such as temperature and extraction time, extracts the activeconstituents with medicines and health protection function selectively from the matrimony vine seed, to reach the purpose of separation and purification.In the super critical point scope, extract, because the non-gas-liquid of fluid of super critical point, but having the biphase characteristics concurrently, viscosity is little, is bordering on gas, and density is big, is bordering on liquid, has good penetration and transitivity, thereby can reduce extraction time.The density of supercutical fluid can be regulated by changing pressure, and the change of density then directly influences its dissolving power, and therefore, supercritical fluid extraction can be controlled the extractability of supercutical fluid with air pressure, promptly extracts needed effective constituent selectively.Its extraction step comprises:
(1) obtain the matrimony vine seed after new fresh fructus lycii pulping separates, matrimony vine seed drying is put into extraction kettle after pulverizing.
(2) extraction kettle pressure is 5-15MPa, and temperature is 97-110 ℃, and the extraction time is 60-250 minute.
(3) extraction-container pressure is 1.0-2.0MPa, and temperature is 90-105 ℃.
(4) flow of propane is 3.0-7.0kg/hr.
(5) yield of Boxthorn Seed Oil is not less than 17%.
