(3) extract: under the conditions of temperature is 10 DEG C -20 DEG C, using polyhydric alcohol extraction, the time is 60min;
(4) coarse filtration: extract is carried out on filter primary filter;
(5) freeze;
(6) thaw;
(7) fine straining: by thaw after primary filtrate secondary filter is carried out on filter, remove further chilled and Precipitation of thawing or the impurity of polymerization, obtain the higher Aloe gel stock solution of purity;
(8) decolour: at ambient temperature, add active carbon powder to pass through stirring in the Aloe gel stock solution after fine straining Decolouring, removes depigmentation thoroughly, good decolorizing effect;
(9) nanofiltration: under normal temperature condition, first organic from molecular cut off 4000da in airtight concentration systems Aloe gel stock solution is filtered by ultrafilter membrane, then from the nanofiltration membrane of molecular cut off 300da, the filtrate of ultrafiltration is carried out Concentrate so that the molecular weight of active component is maintained between 300da-4000da in solution, be concentrated into and slough 90% moisture, obtain 10:1 concentrated solution;
(10) supertension sterilize: be 400mpa in pressure, collaborative temperature be 30 DEG C under the conditions of ultrahigh pressure vessel in will be dense After contracting liquid pressurize 15min, deaerate after pressure is reduced to 0 20min, can sterilize, enzyme denaturing, can preferably keep reed in concentrated solution again Luxuriant growth polysaccharide, the quality of barbaloin isoreactivity composition.
As preferred technical scheme, described polyhydric alcohol is mixed with 1:1 ratio by ethylene glycol and glycerol, extraction effect Really good, purity is high.
As preferred technical scheme, described Aloe is U.S. Curacao kind Aloe.
As preferred technical scheme, described filter adopts horizontal vacuum belt filter.
As preferred technical scheme, the temperature of described freezing is -10 DEG C -15 DEG C, and cooling time is 40min-80min, On the one hand can ensure that original quality of the active component in primary filtrate, on the other hand can allow miscellaneous in primary filtrate Matter preferably precipitates or aggregates into macromole, is easy to the carrying out of fine straining process.
As preferred technical scheme, described thaw point is 25 DEG C -30 DEG C, the quality of primary filtrate will not be caused Destroy.
(3) beneficial effect
Compared with prior art, it has the advantages that the extraction process of the Aloe gel of the present invention to the present invention, The extraction ratio of active aloe composition can be greatly improved, reduce the loss of the active aloe composition that the course of processing causes simultaneously, improve Added value of product.
