Abstract

The technological process of purifying bee glue includes the steps of: extraction of coarse bee glue with ethanol solution and solvent, resting, filtering, distillation to receover ethanol, hot wind drying, cooling, crushing, etc. Compared with available technology, the present invention is simple, practical and low in cost. The wax content and other indexes of prepared bee glue product have reached the standard for natural bee glue and has high heat stability and no coagulation at normal temperature, so that it may be produced into bee glue powder without adding anticoagulant for further use.

Description

A kind of process of bee glue purifying

The present invention relates to a kind of process of bee glue purifying.

Propolis is Apis herborization axillalry bud secretions and mixes self goods and materials, and be applied in the material on Nidus Vespae slit or the inwall, it has good fungus and mildew resistance effect, and inflammation and the diseases many for the mankind have special curative effect, are a kind of natural medicines.Owing to contain more Cera Flava and other impurity in the natural propolis, therefore must could use through purifying.Chinese patent CN1151867A discloses a kind of purification and flouring technology of propolis, and it passes through following steps substantially:

1, thick propolis (picking up from the propolis of Nidus Vespae without any processing) is placed in the water and dissolves.

2, heating dewaxing: be about to be soaked with the water heating of thick propolis, emerge after the feasible wax dissolving wherein, reach separating effect.

3, separate after the waxiness propolis is extracted (as ethanol etc.), filtering and impurity removing with solvent.

4, solvent is reclaimed, obtain the propolis fluid extract.

5, as need powder process, the propolis fluid extract can be crushed to 120 order to 140 orders behind hot air drying, for making at room temperature or being lower than under the room temperature non-cakedly slightly, often add the ratio that the anti-agglomerating agent SiO 2 powder reaches 13-20%.

Adopt the propolis after above-mentioned prior art is purified still to contain wax, fusing point is lower, can only be fluid extract usually, is not easy further processing and use, transports, stores all inconvenient.And after hot air drying adds silicon dioxide powder, though solved agglutinating deficiency, gained be bee glue product in fact, and non-natural propolis extract, its application has been subjected to certain limitation.The defective of existing product is unreasonable the causing of process by prior art.

Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of technology is simple, the product dewaxing fully, be difficult for the process of the bee glue purifying of bonding, Heat stability is good.

Purpose of the present invention can be achieved through the following technical solutions: a kind of process of bee glue purifying, be characterized in, and comprise following processing step:

(1) thick propolis is directly added in the solvent alcoholic solution extract, reflux obtained extracting solution in 30 to 360 minutes in reflux, or merceration obtained impregnation liquid in 1 to 15 day, and the weight ratio of described thick propolis and alcoholic solution is 1: 3 to 1: 10;

(2) with extracting solution or impregnation liquid filtering and impurity removing, filtrate is left standstill, and insulation is 2 to 30 hours in the environment below 15 ℃;

(3) above-mentioned filtrate after standing is filtered with 80 to 400 purpose sieve apertures again;

(4) filtrate that obtains is carried out distilling under reduced pressure and is reclaimed ethanol, does not have the alcohol flavor until distillation;

(5) after the solid formation that distilling under reduced pressure is obtained leaves standstill 3 to 4 days, place 8 mesh sieves or pallet, with less than 100 ℃ hot air drying 30 to 240 minutes;

(6) solid formation behind the hot air drying is cooled off, the reuse pulverizer is crushed to 20 to 80 orders and gets final product.

Compared with prior art, technology of the present invention is simple, practical, cost is low, the propolis paraffin content that adopts prepared of the present invention is less than 3% weight, and other indexs meet the standard of natural propolis, and fusing point is more than 55 ℃, Heat stability is good, noncondensing under the room temperature, needn't add anti-agglomerating agent and get final product powder process, the propolis powder of making is convenient to further use very much.

Below in conjunction with embodiment, the invention will be further described.

Embodiment 1:

Thick propolis is added the alcoholic solution of 10 times of weight, and merceration 15 days filters rear filtrate and leaves standstill, and insulation is 30 hours in 0 to 15 ℃ of environment; Filter 400 orders, reclaim ethanol to there not being the alcohol flavor in 60 ℃ of vacuum concentrating apparatus, take out, place and dried 3-4 days, be put in 8 mesh sieves or other pallets with 60 ℃ hot air drying 240 minutes, cooling is crushed to 20 to 80 purpose powder.

Embodiment 2:

Thick propolis is added the alcoholic solution of 6 times of weight, be heated to and refluxed 2 hours, be chilled to room temperature, filter, filtrate is left standstill, and insulation is 30 hours in environment below 12 ℃.Filter 200 orders, in 60 ℃ of vacuum concentrating apparatus, reclaim ethanol, take out, place and dried 3-4 days to there not being the alcohol flavor, with in 8 mesh sieves or other pallets with 40 ℃ hot air drying 180 minutes, cooling is crushed to 20 to 80 purpose powder.

Embodiment 3:

Thick propolis is added the alcoholic solution of 4 times of weight, be heated to and refluxed 0.5 hour, be chilled to room temperature, filter, filtrate is left standstill, and insulation is 2 hours in-2 ℃ of environment.Filter 80 orders, in 60 ℃ of vacuum concentrating apparatus, reclaim ethanol, take out, place and dried 3-4 days to there not being the alcohol flavor, with in 8 mesh sieves or other pallets with 85 ℃ hot air drying 30 minutes, cooling is crushed to 20 to 80 purpose powder.
