Abstract
The invention relates to a method for extracting pepper oleoresin through ultrasonic continuous countercurrent. The method comprises the following steps: (1) well-chosen black/white pepper dry fruits are smashed to pepper particles to pass through a screen with meshes of 20 to 80, and the screened pepper particles are conveyed in a pre-gumming cage for pre-gumming; (2) the pre-gummed pepper particles are passed in an ultrasonic countercurrent leaching device for extracting; extraction solvent is alcohol with concentration of 65-95%; the weight ratio of the pepper particles to the solvent is (1:5) to (1:10); the ultrasonic frequency range is 10-100 KHz; the leaching temperature is kept in a range of 25-40 DEG C; and the leaching time is 30-90 minutes; and (3) the leached alcohol leachate is passed in a film evaporator for reducing pressure, vaporizing and desolventizing; and obtained concentrate is the pepper oleoresin. The method can improve the dissolution rate of the pepper resin in peppers, shortens the extraction time, reduces the solvent dosage, is easy to operate and is low in labor intensity; and the pepper oleoresin obtained through extraction has excellent dissolution characteristic and dispersity.
Description
Technical field
The present invention relates to process for preparing pepper oil resin, especially a kind of ultrasonic continuous countercurrent extracts the method for pepper oleoresin.
Background technology
Pepper (Piper nigrum) is piperaceae (Piperaceae), the evergreen dungarunga plant of Piper (Piper), is in the world one of important spice crop, and arranged dividing of white pepper, piper nigrum.Autumn Mo, what gather, dry when the pepper fruit is sap green was piper nigrum to time spring; Gather when fruit reddens, pulp is wiped in water logging, and what dry is white pepper.Pepper originates in the tropical rain forest of South Sea Islands various places, and especially take Indonesia as many, also there is production on the ground such as China Hainan, Guangdong, Guangxi, Yunnan.Pepper has the effect of dietotherapeutic, it is aromatic condiment spice indispensable on people's dining table, can be used as again the raw material of essence and medicine, the multiple efficacies such as it has pain relieving, treatment stomach trouble, brings down a fever, anti-oxidant, antibacterial, reducing blood-fat, antitumor, antidepressant, anticonvulsion, anti-nociception and immunomodulatory.Therefore, pepper medically can be used as peptic, antipyretic, diuretic(s) and bronchial mucosa stimulant etc., can treat maldigestion, cold phlegm, cough, enteritis, bronchitis, flu and rheumatosis etc., in food, chemistry and medicine industry, have very widely and use.
The main component that pepper contains is the multiple amidess such as piperine, pepper woods alkali; Also contain simultaneously the volatile oil that is mainly piperonylaldehyde and tetrahydrogeraniol composition.In foodstuffs industry, according to 2003 No. four file of Ministry of Health of the People's Republic of China, pepper oleoresin, pepper oil are approved for the foodstuff additive new variety.Pepper oleoresin is white pepper or piper nigrum natural extract, and cost is low, is easy to store, transport, and it is historical that American-European countries has very long use.
At present domestic aspect the development and application of pepper class seasoning production, still be in the starting stage.In the extracts active ingredients process of plant resources, need the solvent rapid osmotic inner to plant tissue, dissolve effective constituent fast, and strengthen the inside and outside concentration difference of plant tissue, make from inside to outside rapid diffusion of effective constituent.In the traditional intermittence leaching process, the problem that exists the concentration difference of effective constituent in the concentration of effective constituent in the raw material and the solvent to reduce gradually.In order to improve leaching efficiency, increase as far as possible and leach the concentration difference that needs, usually adopt at present the effective constituent in the continuous countercurrent microwave leaching technology extraction plant.In the continuous countercurrent leaching process, the direction of liquid-flow is opposite with the traffic direction of solid materials to be extracted, so that in the raw material in the concentration of effective constituent and the solvent concentration difference of effective constituent keep high value, thereby improve the impellent of whole leaching process, avoided the problem that the concentration difference descends gradually in the leaching process intermittently.
The principle of ultrasonic wave leaching is that ultrasonic wave is applied on the thing to be leached, and by hyperacoustic high-frequency mechanical vibration, accelerates breaking and the transfer of material of cell walls, improves leaching efficiency.When utilizing ultrasonic wave to leach, ultrasonic wave can send tens thousand of hertz or even up to the ultrasonic frequency of several megahertzes, acoustic cavitation, acoustic streaming, acoustic radiation force can appear in communication process.Ultrasonic energy also can be converted into heat energy simultaneously, in moment internal temperature is raise, and accelerates the dissolving of effective constituent.At present, ultrasonic wave has obtained application in the leaching technical field, and has obtained certain effect in the extracts active ingredients of some plants.
Through retrieval, do not find the report that carries out the extraction of pepper oleoresin about ultrasonic countercurrent leaching equipment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of method of ultrasonic continuous countercurrent extraction pepper oleoresin is provided, can improve the solubility rate of pepper resin in the pepper, shorten extraction time, reduce the solvent usage quantity, simple to operate, labour intensity is low.
The present invention solves its technical problem and takes following technical scheme to realize:
A kind of ultrasonic continuous countercurrent extracts the method for pepper oleoresin, it is characterized in that: steps of the method are:
⑴, will be broken into the pepper powder through selected black/white pepper dry powder, it is crossed the 20-80 mesh sieve, the pepper particle after sieving is conveyed in the pre-impregnation dragon and carries out preimpregnation;
⑵ the pepper particle after, the preimpregnation is sent into ultrasonic countercurrent leaching device and is extracted, extracting solvent is the alcohol of concentration 65%-95%, the weight ratio of pepper particle and solvent is 1:5-1:10, ultrasonic frequency scope 10-100KHz, extraction temperature remains on 25-40 ℃, extraction time 30-90min;
⑶ the alcohol leach liquor after, the lixiviate enters thin-film evaporator and carries out the reduction vaporization precipitation, and the gained enriched material is pepper oleoresin.
Advantage of the present invention and positively effect are:
1, the present invention utilizes ultrasonic countercurrent leaching equipment to carry out the extraction of pepper oleoresin, prepares to have excellent dissolution characteristic and dispersed pepper oleoresin product, improves the lixiviate yield, and reduces production costs.
2, the present invention combines countercurrent leaching technology and Ultrasonic Wave-Assisted Extraction technology, be applied in the leaching process of pepper oleoresin, accelerate the dissolving of effective constituent in the pepper particle, diffusion and the mass transfer of promotion solvent, improve the solubility rate of pepper resin in the pepper, shortened extraction time, reduced the solvent usage quantity, simple to operate, labour intensity is low, and extraction yield is high, can significantly reduce production costs.
3, the present invention adopts the ultrasonic continuous countercurrent extractive technique to extract pepper oleoresin, utilize hyperacoustic cavitation effect and mechanical vibration effect, accelerated the leaching of soluble material in the pepper particle, can finish at normal temperatures the lixiviate of pepper particle, compare 50 ℃-60 ℃ extraction temperature of simple alcohol extraction process, save the consumption of the energy, and extraction time has been shortened to 30-90min from 2-4h, improved greatly extracting efficiency.The pepper oleoresin yield that reclaims in the alcohol leach liquor behind the ultrasonic countercurrent leaching with do not utilize ultrasonic alcohol extraction process to compare can to improve about 10%.
