Adopt such scheme, can be met " used for cosmetic aloe products " (QB/T2488-2000) 2: 1 concentrated solution products of decolored aloe gel of standard.This product can use for making high-grade Aloe cosmetics.

The specific embodiment of 2: 1 concentrated solution processing methods of used for cosmetic decolored aloe gel, do as detailed below:

The processing environment condition: 2: 1 concentrated solutions of processing used for cosmetic decolored aloe gel will be finished in the cleaning sterile workshop of GMP compatible, and the air cleaning rank satisfies 100,000 grade standards.This environmental requirement is that the machining experiment by aloe raw material product up to standard proposes.

Select materials: select for use by the nuisanceless standard plantation and the fresh blade of Aloe vulgaris at growth 18 monthly ages of expiration, rejecting has the scab position; The freshness requirement should be controlled within 8 hours from Aloe plant harvesting blade to factory process.This technological requirement be by mycete grow the experiment determined.The fresh blade of Aloe that is mechanically damaged when experimental results show that harvesting is under condition more than 15 ℃, and the blade injury position will have mycete to produce after 8 hours.

Cleaning and sterilization: divided for three steps carried out.The first step is put into the XY type recirculated water cleaning machine made from rustless steel with the Fresh leaf of aloe after selecting materials, and washes Fresh leaf of aloe surface silt and dirt off with meeting " drinking water sanitary standard " clean water (GB5749).Second step put into the cleaning and sterilizing pond that fills Ozone Water with Fresh leaf of aloe and soaked 5 minutes, and Fresh leaf of aloe is sterilized and removes pesticide residues and handle.Ozone Water is to enter in the water of cleaning and sterilizing pond formedly after gas-liquid mixing pump mixes by the certain density ozone that pretreated air admission ozonator produces, and the ozone concentration of its Ozone Water should be controlled at 10-20mg/m ³The 3rd step was put into mobile sterilized water rinsing 3 minutes with Fresh leaf of aloe, with bacteriological protection cross-contamination in the cleaning and sterilization process.This technological requirement is determined by GB/T7918.2-1987 total number of bacteria assay method and experimental result.

Peeling: the Fresh leaf of aloe of the Aloe peeling machine made from rustless steel after with cleaning and sterilization carries out peeling to be handled, and the meat (gel) of bright leaf is separated with skin, and it is standby to get Aloe mesophyll (gel).

Making beating: the Aloe beater made from rustless steel breaks into aloe juice with Aloe mesophyll (gel).

Squeezing: with squeezer aloe juice is squeezed the juice, its juice is aloe gel 1:1: 1 stock solution.It is dried more good more to squeeze the juice, with the no longer excessive degree of being of juice.

Fine grinding: adopt colloid mill that aloe stoste is ground, make the further refinement of aloe stoste, and reach the homogenizing purpose.

Filter: through the aloe stoste that fine grinding obtains, also have the thinner fibrous tissue of part granule to be suspended in the juice, along with the prolongation meeting of resting period is slowly sunk, stable unfavorable to product.Therefore, adopt the centrifugal fine filter of ultrahigh speed to remove the thin sticking granule of slow (≤0.2 mm/second) of those sedimentation velocity.

Decolouring: the aloe gel 1:1 that obtains after filtering: the 1 stock solution processing of decolouring.Aloe gel 1:1: adsorption decoloring method is adopted in the decolouring of 1 stock solution, and adsorbent uses the fine powder active carbon.Fine powder active carbon addition is an aloe gel 1:1: 1.5% of 1 stock solution weight.During operation, with the aloe gel 1:1 that adds behind the fine powder active carbon: 1 stock solution, make its temperature bring up to 48 ℃～50 ℃, the time kept 20 minutes, was cooled to room temperature then.This technological requirement is determined according to experimental result.

Secondary filter: will be through the aloe gel 1:1 after decolouring is handled: 1 stock solution adopts the deckle board filter press to remove the activated carbon adsorption thing, and aloe gel 1:1: remaining colloid, fiber and impurity etc. in 1 stock solution.

Membrance concentration: the decolored aloe gelin proportion collagen solution behind the secondary filter is entered membrane separation concentrated compression apparatus carry out membrance concentration.The membrance concentration biggest advantage is to realize that normal temperature condition concentrates down, avoids in the course of processing Yin Wendu too high and the Aloe bioactive ingredients is run off, and has kept the color and luster and the local flavor of product, has guaranteed the quality of product.Membrance separation is to utilize the macromolecule semipermeable membrane, with the pressure differential of film both sides, when impelling some molecule in the fluid to see through semipermeable membrane and be retained down, to obtain a kind of isolation technics of some composition in the fluid.When by semipermeable membrane be solvent, then solution has obtained to concentrate, this process is exactly a membrance concentration.Decolored aloe gelin proportion collagen solution membrance concentration should adopt the reverse osmosis isolation method, and osmotic pressure should be controlled at 5.0～8.0MPa.This technological requirement is determined by decolored aloe gelin proportion collagen solution membrance concentration experimental result.Through membrance concentration, when the volume of concentrated solution reaches two/for the moment of decolored aloe gel stock solution volume, the concentrated solution of this moment is 2: 1 concentrated solutions of decolored aloe gel.

Sterilization: decolored aloe gel concentrated solution sterilization in 2: 1 is to guarantee the constant important step of Aloe stable components.Sterilizing methods adopts pasteurization, and sterilising temp is controlled at 70 ℃, and sterilization time is 20min.This technological requirement is determined by decolored aloe gel concentrated solution sterilization in 2: 1 experiment.
