Description

A kind of capsaicine subcritical fluid extraction device

Technical field

Capsaicine extractive technique field is the utility model is related to, specially a kind of capsaicine subcritical fluid extraction device.

Background technology

Capsaicine also known as capsaicine, popular name Capsaicin is the alkaloid of a kind of phenolic hydroxy group, wherein main being formed by five kinds Composition, respectively capsaicine, dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin.Capsaicine thermostabilization Property it is high, sterling be white needle-like crystals under usual conditions, nontoxicity, but excitant is very strong, is soluble in methanol, ethanol, acetone, three In chloromethanes, dichloromethane, ethyl acetate and alkaline aqueous solution, cold water is insoluble in.The capsicum of low concentration is usually with pigment, with sugar Body, Phospholipids form the molten thing of violet oil.

Capsaicine is primarily present in the tire reality tissue and chili peel and seed of pepper fruit, and content is 0.05~1.0%, The difference because of the difference of kind, maturity, weather conditions and soil property etc., is typically accumulated with maturity.It is peppery Green pepper element is the main matter for causing acid in capsicum, and the content of a ten thousandth can feel obvious pungent in food.

Capsaicine can be used for many fields, and low-purity chilli extract can be widely used in food industry as additive；Purifying Capsaicine afterwards is wider in pharmaceuticals industry application, such as has notable adjustment effect to angiocarpy, PFT, stomach and intestine function；It can promote Enter fat metabolism；Acted on easing pain and diminishing inflammation, can be made into potent analgesic；Interior free yl can be suppressed, reduce cell carcinogenesis；With Morphine shares, and can mitigate the withdrawal syndrome of Morphinoid drug, reduces additive^[13]；To chronic rheumatic arthritis, ox-hide Tinea, baldness have good therapeutic action.There is high-purity capsicum cellulose crystal tear-gas to urge the effect of sneezing, military affairs can manufacture tear bombnoun, Tear-gas rifle and defensive weapon.Capsaicine has the active material for preventing biological attachment, can agriculturally be used as biochemical pesticide, be used for Pest and mouse, rabbit etc.；It is used for nontoxic antifouling paint additive on ship；Add on cable, optical cable for protection against rodents coating Add agent；It is used for termite-proof coating etc. on wooden building.

At present, the agent of capsicum stomach strengthening and digestion promoting, capsicum diet food, capsicum health medicine etc. are also among research and development.It is it is expected that domestic The application of outer capsaicine will rapidly expand and bring wide market prospects.

Conventional high-purity capsaicine extracting method has：Solvent extraction method, adsorpting column chromatography method, supercritical carbon dioxide extracting Method.

（1）Solvent extraction method：Using scarlet chilli as raw material, extracted after crushed with organic solvent, be concentrated to give one kind Kermesinus is referred to as capsicum oleoresin, extract yield is generally chilli total amount in the world to orange/red oil 15%.By capsicum oleoresin through ether, ethanol and alkaline aqueous solution, or further extracted with petroleum ether, dichloroethanes equal solvent dense After contracting, crystallize to obtain thick capsaicine crystallization through petroleum ether or n-hexane.Equipment needed for organic solvent extractionprocess is simple, production cost It is relatively low, but there is product purity it is poor, have the problems such as peculiar smell, solvent residual amount is high.

（2）Adsorpting column chromatography method：Capsicum oleoresin is extracted with acetone, petroleum ether, 59% ethanol, then knot is used as using ether Brilliant solvent, obtain thick capsicum cellulose crystal.Crystallized after purification through silica gel column chromatography again, obtain capsaicine sterling.Adsorpting column chromatography method Recovery rate is relatively low.

（3）Supercritical carbon dioxide extraction method：Fukaya, Kyoo etc. of Japan using supercritical carbon dioxide as solvent, with Ethanol is entrainer, and temperature is fixed on 50 DEG C, and pressure is 9.8 × l0⁶MPa, be directly isolated to obtain from capsicum 80% or so it is peppery Green pepper element.Supercritical carbon dioxide extraction method can obtain the capsaicine sterling for having high added value, purity high, but supercritical fluid extracts Taking technology presently, there are, equipment investment is big, and extraction kettle can not operate continuously, the space-time yield of equipment than relatively low and operation into The problems such as this is high, thus can be not yet widely used in China in industrial production.

Capsaicine extraction process in China's uses solvent method mostly at present, and extraction step is longer, and crystallization is cumbersome, time-consuming, causes Resource utilization is low, and cost increases.The universal bad adaptability of extraction process of use, the capsaicine recovery rate of different sources capsicum become Change is very big, influences industrial-scale production.The adaptability of capsaicin content assay method is also poor, for the capsicum of different sources And capsaicin product, accuracy, the rate of recovery of its capsaicin content measure change greatly, the final quality determination for influenceing product.Mirror In above reason, capsicum deep processing producer is more to extract based on capsochrome, and constitute competition fierceness, and annual production only reaches 20 tons Above production scale could support reluctantly.
