Problems solved by technology

But with the aloe gel concentrated juice that existing aloe gel concentration process obtains, the soluble solid content wherein can only reach about 7%, is difficult to obtain the high power aloe gel concentrated juice that soluble solid (quality) content reaches more than 30%, And in the freeze-drying process, due to the low soluble solid content and high water content, the drying process requires a lot of sublimation water, not only the drying cycle is long, the energy consumption is large, and at the same time, due to the low soluble solid content, the solid matter obtained by freeze-drying is less , which leads to higher costs and makes it difficult to meet market demand

Embodiment 1

[0030] A. The harvested aloe vera leaves are cleaned, scrubbed, disinfected and cleaned for the first time, after the second cleaning, thorns and skins are removed, crushed and squeezed, and then subjected to conventional ultra-high temperature instantaneous sterilization to obtain aloe vera gel thick juice 27 Ton;

[0031] B. According to the addition amount of 30mL / ton of aloe vera gel thick juice, add commercially available food-grade pectinase 810mL in the aloe vera gel thick juice obtained in step A, then add commercially available Food grade activated carbon 54kg, add the market-bought food grade diatomite 27kg of 0.1% of aloe vera gel thick juice quality simultaneously, stir 40min and carry out enzymolysis, decolouring, filter and remove slag and remove filter residues such as aloe fiber, gac, diatomite, to After the filtrate is subjected to conventional ultra-high temperature instantaneous sterilization, it is naturally cooled to below 20°C to obtain clarified aloe ver...

Embodiment 2

[0039] A. The harvested aloe vera leaves are cleaned, brushed, disinfected and cleaned, cleaned twice, thorns and skins are removed, crushed and squeezed, and then subjected to conventional ultra-high temperature instantaneous sterilization to obtain aloe vera gel thick juice 32.2 Ton;

[0040] B. According to the addition amount of 40mL / ton of aloe vera gel thick juice, add commercially available industrial grade pectinase 1288mL in step A gained aloe vera gel thick juice, press 0.3% of aloe vera gel thick juice quality again, add commercially available 96.6kg of industrial-grade activated carbon, and 64.4kg of commercially available industrial-grade or food-grade diatomaceous earth of 0.2% of the mass of aloe vera gel thick juice, stirred for 35 minutes to carry out enzymatic hydrolysis and decolorization, and filtered to remove slag to remove aloe fiber, activated carbon, and diatoms Soil and other filter residues, the filtrate is subjected to conventional ultra-high temper...

Embodiment 3

[0047]A. The harvested aloe vera leaves are cleaned, scrubbed, disinfected and cleaned for the first time, after the second cleaning, and the side thorns and skins are removed, crushed and squeezed, and then subjected to conventional ultra-high temperature instantaneous sterilization to obtain aloe vera gel thick juice 40 Ton;

[0048] B. According to the addition amount of 50mL / ton of aloe vera gel thick juice, add commercially available food-grade pectinase 2000mL to the aloe vera gel thick juice obtained in step A, then add commercially available 160kg of food-grade activated carbon, at the same time add 60kg of industrial grade or food-grade diatomaceous earth 0.15% of the mass of the aloe gel thick juice, stir for 30min to carry out enzymatic hydrolysis and decolorization, filter to remove slag to remove aloe fiber, activated carbon, diatomite, etc. For the filter residue, the filtrate is subjected to conventional ultra-high temperature instantaneous sterilization, and th...

Abstract

The invention provides a preparation method of high-power aloe vera gel dry powder. The preparation method comprises the following steps: cleaning collected aloe vera blades, removing edge burrs and peels, smashing, juicing, and sterilizing to obtain crude aloe vera gel; adding pectinase, activated carbon and kieselguhr for enzymolysis and decoloration; filtering and sterilizing to obtain clear aloe vera gel normal juice; successively filtering by a titanium rod filter of which the aperture is 20 mu, a microfiltration membrane of which the aperture is 0.3 mu and a reverse osmosis membrane; and concentrating, and carrying out conventional low-temperature vacuum concentration and conventional freeze-drying to obtain the high-power aloe vera gel dry powder. The preparation method disclosed by the invention has the advantages of low energy consumption and raw material saving, is convenient to operate and maintain and is easy to automatically control; moreover, possibility of polluting andremaining products is lowered, the colors of substances are not changed, and active ingredients can be totally reserved. The obtained high-power aloe vera gel concentrated juice has constant volume, is loose and porous, can basically keep the original shape, color, taste and nutrition ingredients and has excellent rehydration capability.

Description

technical field [0001] The invention relates to a preparation method of high-power aloe vera gel dry powder, which belongs to the technical field of plant processing. Background technique [0002] Aloe vera is a eutrophic plant. During processing, it is susceptible to fermentation and deterioration due to the influence of the production environment and temperature. It has become the development direction of the global aloe processing industry to research and develop efficient and stable high-power aloe vera gel concentrate preparation and drying technology. But with the aloe gel concentrated juice that existing aloe gel concentration process obtains, the soluble solid content wherein can only reach about 7%, is difficult to obtain the high power aloe gel concentrated juice that soluble solid (quality) content reaches more than 30%, And in the freeze-drying process, due to the low soluble solid content and high water content, the drying process requires a lot of sublimation ...
