Adopt such scheme, can be met " food decolored aloe goods " (QB/T2489-2000) decolored whole leaf aloe 10:1 of standard: 1 inspissated juice product.This product can use for making high-grade aloe food.
The specific embodiment of 10: 1 inspissated juice processing methods of food decolored whole-leaf aloe, do as detailed below:
The processing environment condition: processed food is used decolored whole leaf aloe 10:1: 1 inspissated juice 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 determined by the machining experiment of aloe raw material product up to standard.
Select materials: select for use by the nuisanceless standard plantation and the fresh blade of aloe barbadensis Miller 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 mould 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 mould 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 stainless 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 carried out sterilization and removes the residues of pesticides processing.Ozone Water is to enter certain density ozone that ozone generator produces by pretreated air to enter in the water of cleaning and sterilizing pond formedly after gas-liquid mixing pump mixes, 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 pollution 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.
Finishing: the Fresh leaf of aloe behind the cleaning and sterilization is repaired, excised bright blade root portion's white portion and blade tip, ream the thorn on leaf margin both sides.
Making beating: the Fresh leaf of aloe after the aloe beater made from stainless steel will repair breaks into aloe and starches.
Squeezing: with squeezer the aloe slurry is squeezed the juice, its juice is exactly whole leaf aloe 1:1: 1 Normal juice, income rate are the 70-85% of bright leaf.This is the data of gained by experiment.
Fine grinding: adopt colloid mill that Aloe original juice is ground, the time was controlled at 15～20 minutes, made the further refinement of Aloe original juice, and reached the homogeneous purpose.
Filter: through the Aloe original juice that fine grinding obtains, also have the thinner fibr tissue of part particle 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 particle of slow (≤0.2 mm/second) of those sinking speed.
Decolouring: the whole leaf aloe 1:1 that obtains after filtering: the 1 Normal juice processing of decolouring.Whole leaf aloe 1:1: adsorption decoloring method is adopted in the decolouring of 1 Normal juice, and adsorbent uses the fine powder active carbon.Fine powder active carbon addition is a whole leaf aloe 1:1: 2% of 1 Normal juice weight.During operation, with the whole leaf aloe 1:1 that adds behind the fine powder active carbon: 1 Normal juice, make its temperature bring up to 50 ℃～52 ℃, the time kept 30 minutes, was cooled to normal temperature then.This technological requirement is determined according to experimental result.
Secondary filter: will be through the whole leaf aloe 1:1 after decolouring is handled: 1 Normal juice adopts the deckle board pressure filter to remove the charcoal absorption thing, and whole leaf aloe 1:1: remaining colloid, fiber and impurity etc. in 1 Normal juice.
