Embodiment 1

[0028] A method for extracting an aloe extract, comprising the steps of:

[0029] 1) Pick the aloe vera that has no disease or spot on the surface, wash it, dry it, and peel it;

[0030] 2) Finishing: Dice the peeled aloe vera and put it into hot water at 90-100°C for 10 seconds;

[0031] 3) drying: the aloe vera after greening is filtered to remove moisture, and dried with hot air at a temperature of 45-65°C until the final water content of the aloe vera is lower than 10%;

[0032] 4) crushing and sieving: coarsely crushing the dried aloe, then passing the obtained primary crushed material through a 60-mesh sieve to obtain aloe powder with a particle size less than 250 μm;

[0033] 5) After adding ethanol solution to the aloe vera powder for soaking, use microwave radiation with a power of 400W to extract, filter to obtain the first extract, recycle the solvent to obtain the first concentrated solution, and filter residue for subsequent use; wherein the feed liquid of aloe v...

Embodiment 2

[0039] A method for extracting an aloe extract, comprising the steps of:

[0040] 1) pick the aloe vera that has no disease or spots on the surface, wash it, dry it, and peel it;

[0041] 2) Finishing: Dice the peeled aloe vera and put it into hot water at 90-100°C for 30 seconds;

[0042] 3) Drying: the aloe vera after greening is filtered to remove moisture, and vacuum-dried at a temperature of 45-65° C., until the final moisture content of the aloe vera is lower than 10%;

[0043] 4) crushing and sieving: coarsely crushing the dried aloe, then passing the obtained primary crushed material through a 60-mesh sieve to obtain aloe powder with a particle size less than 250 μm;

[0044] 5) After adding ethanol solution to the aloe vera powder for soaking, use microwave radiation with a power of 800W to extract, filter to obtain the first extract, recycle the solvent, obtain the first concentrated solution, and filter residue for subsequent use; wherein the feed liquid of aloe ve...

Embodiment 3

[0050] A method for extracting an aloe extract, comprising the steps of:

[0051] 1) Pick the aloe vera that has no disease or spot on the surface, wash it, dry it, and peel it;

[0052] 2) Finishing: Dice the peeled aloe vera and put it into hot water at 90-100°C for 20 seconds;

[0053] 3) drying: the aloe vera after greening is filtered to remove moisture, and dried with hot air at a temperature of 45-65°C until the final water content of the aloe vera is lower than 10%;

[0054] 4) crushing and sieving: coarsely crushing the dried aloe, then passing the obtained primary crushed material through a 60-mesh sieve to obtain aloe powder with a particle size less than 250 μm;

[0055]5) After adding ethanol solution to the aloe vera powder for soaking, use microwave radiation with a power of 600W to extract, filter to obtain the first extract, recycle the solvent, obtain the first concentrated solution, and filter residue for subsequent use; wherein the feed liquid of aloe vera...

Abstract

The invention relates to an aloe extract extraction method, and belongs to the technical field of foods and medicines. The aloe extract extraction method comprises the following steps that 1, aloe with the surface free of disease and spot are picked, cleaned, aired, peeled, subjected to fixation, dried, crushed and screened to obtain aloe powder, an ethanol solution is added into the aloe powder, soaking is conducted, then extraction is conducted through microwave radiation, filtration is conducted to obtain a first extracting solution, solvent is recycled, a first concentrated solution is obtained, and filter residues are for standby application; 2, the filter residues are added into a water saturated butanol alcohol solution to be soaked, ultrasonic extraction is conducted, filtration is adopted, a second extracting solution is obtained through filtration, solvent is recycled, and a second concentrated solution is obtained; 3, the first concentrated solution is mixed with the second concentrated solution, drying is conducted, and then aloe extracts are obtained. The extracted aloe extracts are high in curative effect, stable in quality, high in extraction rate, simple in technology, convenient to operate, low in cost and suitable for industrial production.

Description

【Technical field】 [0001] The invention relates to the technical fields of food and medicine, in particular to an extraction method of aloe extract. 【Background technique】 [0002] Aloe vera is a perennial evergreen herb of Liliaceae. The leaves are clustered, large and thick, in seat shape or on the top of the stem. The leaves are often lanceolate or short and wide, with sharp-toothed thorns on the edges. The inflorescence is umbellate, raceme, spike-shaped, conical, etc., with red, yellow or red spots, six petals and six pistils, and the base of the perianth is connected into a tube shape. According to public information, the chemical components of aloe include aloe polysaccharides, aloin, aloe-emodin glycosides, isoaloe-emodin glycosides, etc., which have the functions of enhancing immune function, anti-tumor, laxative, anti-bacterial, anti-gastric damage and liver protection. skin etc. [0003] There are several problems in the existing aloe extraction method. One is th...
