Abstract
The present invention relates to a technology for removing lead from propolis, which comprises the following steps: medical stones, zeolite, ion exchange resin, etc., which are pretreated, are respectively loaded in ion exchange posts to form into connection in series. The propolis leached in edible alcohol uses diatomite, etc. to accelerate the sedimentation. After a centrifugal filtration procedure, propolis alcohol liquid is prepared, and a little acetic acid is added for adjusting the pH value between 5.0 and 6.0. The propolis liquid passes the exchange posts connected in series. After low-temperature condensation and alcohol reclamation, a finished produce from which lead is effectively removed is prepared. The lead content is at most 0.02 mg/kg, and the loss of active ingredients of propolis is at most 1% in the process of removing lead. The lead removing effect of the technology is favorable, the equipment is simple, the operation is convenient and the technology is suitable for being used in various factories which use dissolvent, such as alcohol, etc. for refining propolis.
Description
Technical field: the present invention relates to a kind of propolis deleading technique.
Technical background: propolis is the resin on honeybee herborization young shoot and the trunk, and sneaks into its mandibular gland secretion and a kind of colloidal solid thing with aromatic odor of processing such as beeswax.Propolis is approximately by 50% resin and the fragrant liquid of plant, and 30% beeswax, 10% aromatic oil material, 5% pollen and 5% comprise other material composition of organ clast.Propolis has significantly and unique biological is active, is applied to fields such as medicine, food, chemical industry more and more widely, and development prospect is wide.
At present, along with the raising of China's living standards of the people, the apiculture of China is flourishing day by day, and bee product, particularly bee glue product more and more are subjected to people's welcome and favor, and is also more and more deep to the research of bee product simultaneously.Because contain tens classes in the propolis, more than 300 kind of natural component, comprising more than 30 kinds of trace element, 20 several amino acids that human body is necessary, tens of kinds of aromatics, more than 70 kind of Flavonoid substances also have rich organic acid, terpenoid substance, vitamin, enzyme, polysaccharide etc. to have the natural component of BA.Propolis has prevention and supplemental treatment effect preferably to human numerous disease, can be used for supplemental treatment beriberi, acne, flat wart, onychomycosis, eczema etc., have well activate blood circulation and disperse blood clots, softening blood vessel, reducing blood lipid, sterilization, pain relieving, hypoglycemic, prophylactic treatment diabetes, anti-oxidant, antitumor, delay senility, improve gastrointestinal function, stop platelet aggregation, improve effects such as microcirculation.
Because higher lead content is arranged in the propolis, and (lead 〉=5mg/kg) takes for a long time not that the deleading propolis certainly will cause chronic lead poisoning, so deleading is a CCP in the propolis production and processing.There are not deleading technique, lead content severe overweight in some producer's bee glue purifying technology at present; Some producer adopts the natural sedimentation deleading, and elapsed time is long, and lead content 〉=2mg/kg, surpasses the relevant requirement of limiting the quantity of of country; Some enterprises adopts adsorbents adsorb deleadings such as active carbon, and its effect can not guarantee and active ingredients such as a large amount of flavonoids of adsorbents adsorb such as active carbon, thereby causes a large amount of losses of functional component; Also have indivedual producers to adopt technology deleadings such as the lixiviate of gradient alcohol, freezing sedimentation, means of supercritical extraction propolis etc., its deleading is respond well, but equipment requires height, and complicated operation is not suitable for popular the popularization.
The invention provides a kind of deleading technique easily, deleading is respond well, and equipment is simple, easy to operate, is applicable to each producer with alcohol equal solvent bee glue purifying.
Summary of the invention: the present invention is achieved in that and will be respectively charged in the ion exchange column after the preliminary treatment such as medical stone, zeolite, ion exchange resin, formation is connected in series, after the propolis after the edible alcohol lixiviate is with acceleration sedimentation, centrifugal filtrations such as diatomite, becoming the propolis wine seminal fluid, add little acetic acid and make its pH between 5.0-6.0.Exchange column by being connected in series then, cross behind the post propolis liquid through low temperature concentrate, recovered alcohol, just become the finished product of effective deleading, its lead content≤0.02mg/kg, deleading process loss of effective components≤1%.
Concrete technology is as follows:
1. medical stone, zeolite, ion exchange resin preliminary treatment
40-100 order medical stone, zeolite are cleaned the back soaked 10-24 hour with weak acid, and then extremely neutral with rinsed with deionized water, adorn post then.
Ion exchange resin is selected the weak-type cationic ion-exchange resin for use, requires itself and organic adsorption capacity little, with being rinsed into neutral back dress post with ionized water after acid, the alkali treatment.
2. the selection of pillar
Ion exchange column requires to make with pmma material or other non-toxic materials, and its post directly is 25-200 centimetre, and the post height is 1.0 meters-2.5 meters, and wall thickness is 3 millimeters-45 millimeters, the two ends end socket.
3. mode is connected in series
Medical stone post, zeolite column, ion exchange resin column connected mode are seen accompanying drawing 3.
Fig. 1 is connection diagram simply connected figure; Fig. 2 is connection diagram duplex figure; Fig. 3 is connection diagram three figure.
4. propolis liquid is accelerated sedimentation
Propolis liquid is added the 0.1%-1% diatomite (100-200 order) of propolis amount after initial filter, stir 0.5 About-2 hours, leave standstill after 12-48 hour and will precipitate centrifugal removal, propolis liquid is for subsequent use.
5. cross post
Propolis liquid is flow through the exchange column that connects, and flow velocity is looked post footpath and post Gao Erding, and flow is the 0.1-1 ton / hour.
6. concentrate, finished product
The propolis liquid of crossing the post deleading through low temperature concentrate, alcohol reclaims, the packing of product, get final product plumbously≤ 0.02mg/kg the propolis finished product.
Deleading technique is extracted in technological process 1 propolis virgin rubber for example:
Virgin rubber pulverizing → 4-6 doubly 2-3 days → centrifugal impurity elimination of 95% alcohol lixiviate → freezing paraffin removal → diatomite quickens precipitation → accent PH → mistake ion-exchange columns in series → concentrated finished product
Technological process is the processing art for extracting propolis and removing lead from it in 2 beehive drop cloth, beehive cover net, the beekeeping equipment for example:
Beehive drop cloth, beehive cover net → 2-6 be 95% alcohol-pickled → centrifugation or isolated by filtration → freezing paraffin removal → diatomite acceleration sedimentation → mistake ion-exchange columns in series doubly
