Abstract
A continuous raw material feeding process for extracting garlic oil by supercritical CO2 features that the garlic juice as raw material is continuously fed. Its advantages include low cost, high efficiency and extracting rate, and high content of allicin.
Description
Technical field:
The invention belongs to a kind of method of extracting Oleum Bulbus Allii, relate in particular to a kind of method of from the garlic juice of continuously feeding, extracting Oleum Bulbus Allii with supercritical co.
Background technology:
Garlic is the bulb of Liliaceae allium garlic (Allium Sativum.), have another name called giant garlic, calabash, only garlic, single clove garlic, originate in western part of Asia, because it is rich in bioactive ingredients and nutritive ingredient, so before more than 5,000 years, people just begin edible garlic.According to record, imperial court of ancient Egypt makes slaves can withstand arduous heavy manual work under the heat of desert, allows their edible garlic to improve endurance, and this explanation is human recognizes that very early garlic has the high effect of improving the body and culature.China use garlic comes diseases prevention, curing the disease also has long history, " not Lu ", " at all times ", " Puji Fang ", Compendium of Material Medica etc. be all on the books, point out that garlic has functions such as " logical the five internal organs, reach all keys, cold removing wet, avoid evil spirits evils, too fat to move, the eliminate indigestion of disappearing eat ".In recent years, about the pharmaceutical use of garlic, domestic and foreign literature has many reports, thinks that it can prevent and treat the content of the nitrite in coronary heart disease, blood fat reducing, the reduction stomach; Normal food garlic can reduce the sickness rate of cancer of the stomach, can promote intestinal secretion, helps digest, the sweating diuresis.Garlic also is a broad-spectrum antibiotics, belongs to the immune stimulating herbal medicine, multiple coccus, bacillus, mould, fungi, virus, ameba, trichomonas vaginitis, pinworm etc. is all had suppress and killing action.Extremely medical always scholar of the mystery effect of garlic and nutritionist's concern.
Contain Bulbus Allii quintessence oil in the garlic, its main component is organic sulfide (wherein more important component is an allicin).These materials make garlic have drug effects such as anti-inflammatory, anticancer, antibiotic, step-down, treatment cardiovascular and cerebrovascular diseases just.But the sulfocompound of garlic makes garlic have off-odor and pungent, directly edible having a stomach upset, and its purposes is very limited.From garlic, extract Oleum Bulbus Allii, slough its stink; And then make capsule or injection.The use value that improves garlic receives scientific worker's very big concern always.
In the numerous effective constituent of Oleum Bulbus Allii, allicin enjoys high praise in actual applications with its high reactivity.But in actual production and storage and transport process, because allicin has unstable-sulfinic acid structure, therefore easy deterioration by oxidation or be decomposed into other material.
At present, the extracting method of Oleum Bulbus Allii mainly contains steam distillation and organic solvent method.Because being heated, easily decomposes allicin, so the steam distillation product yield is low, and poor quality.Organic solvent method yield height, but organic solvent is inflammable and explosive, to the requirement height of production operation; More, pursuing environmental protection day by day, praising highly and abandoned by the people gradually natural today because of its toxic side effect.
Supercritical carbon dioxide extraction method is the Perfected process that extracts Oleum Bulbus Allii, but if be raw material (Sun Junshe with garlic solid substance (garlic grain etc.), garlic and onion local flavor thing and extraction thereof, China's seasonings, 1995,10: 9/ gold medal continues black, CN1124591A), its intermittent type operating method has improved the cost of investment of suitability for industrialized production, has limited throughput.Solvent extraction and supercritical co purification bonded method (Zang Zhiqing, the experimental study of supercritical continuous carbon dioxide extraction garlic oil, Chinese grain and oil journal, 1998,6,21-24), introduced solvent, increase operational path, prolonged the time, undesirable economically.
Summary of the invention:
The purpose of this invention is to provide a kind of high-level efficiency, low cost, produce the method for high-quality Oleum Bulbus Allii.
Method of the present invention is to be the raw material of supercritical carbon dioxide extraction with the garlic juice, carries out the continuous production of Oleum Bulbus Allii in the mode of continuously feeding.Its concrete steps comprise:
(1). the peeling garlic clove is pulverized with juice extractor and is squeezed the juice, filter garlic juice;
(2). garlic juice feeds from the top of extractor; With carbonic acid gas in carbonic acid gas: garlic juice=1～20: 1 weight part ratio feeds from the extractor bottom, and garlic juice is carried out counter-current extraction, and carbonic acid gas flows out from the extractor top; Garlic juice after the extraction flows out from the extractor bottom, extracting pressure 10～40MP, and temperature is at 30～60 ℃;
(3). flow out from the extractor top, the carbonic acid gas that contains Oleum Bulbus Allii enters the separator decompression separation.Carbon dioxide gas flows out from the top of separator; Oleum Bulbus Allii is emitted separating pressure 1～9Mpa, 10～60 ℃ of separation temperatures from the separator bottom.
Step (1) is the situation of selling well seasonings: garlic powder after the solid substance drying and crushing of residue.
Step (1), also available squeezing machine is squeezed the juice.
Aforesaid extractor is the extractor of spray column, packing tower, sieve-tray tower or rotating disc contactor.
The present invention has following advantage:
(1) is the raw material of supercritical carbon dioxide extraction with the garlic juice, realized continuously feeding.Thereby reduced investment of production equipment; The extractor of equal volume, efficient improves 2～3 times; Equipment is worked under steady pressure, does not have operations such as supercharging decompression repeatedly, and the life-span improves greatly.
(2) all technology all realizes under the condition of gentleness.Product extraction yield height; Allicin content height in the product Oleum Bulbus Allii, stability is strong.
(3) technology is simple, and energy consumption is low, environmental friendliness.
