Description
Technical Field
The invention relates to the technical field of biological materials, in particular to the field of natural polymers, the preparation technology of biological membranes and pervaporation membranes (Pervaporation Membrane), and in particular relates to a method for promoting aloe polysaccharide to form the pervaporation membranes.
Background
The pervaporation membrane technology is a novel membrane separation technology. The membrane technology is distinguished from other membranes and has the property of a particular screening substance. This technique is often used for separation of liquid mixtures, and has the outstanding advantage of being able to carry out separation tasks which are difficult to accomplish by conventional methods such as distillation, extraction, adsorption, etc., with low energy consumption. The method is particularly suitable for separating near-boiling point and constant-boiling point mixtures which are difficult to separate or cannot be separated by common rectification, has obvious economic and technical advantages for separating small amount of organic pollutants in waste water by removing trace water in an organic solvent and a mixed solvent, and can also be used for continuously removing reaction products by chemical reaction coupling so as to obviously improve the reaction conversion rate.
Although a variety of separation membranes have been industrialized, existing membrane-based separation processes rarely meet the green environmental requirements. A large amount of toxic substances are used in the membrane process, so that a large amount of treatment is required downstream. In addition, most polymers used in membrane fabrication, such as Polyethersulfone (PES), polysulfone (PSf), polyvinylidene fluoride (PVDF), and Polyamide (PA), are petrochemical-based polymers. In recent years, global interest in polysaccharide-based polymers has increased not only to replace petrochemical-based polymers, but also to develop innovative biotechnology as a promising material. Different types of polysaccharides, such as cellulose, starch, chitin, alginate and chitosan-based carbohydrate polymers have been used in the manufacture of pervaporation membranes. The pervaporation membrane naturally produced in the process of evaporating aloe polysaccharide liquid from natural aloe polysaccharide liquid is not reported at present.
Humans have been looking for ways to heal wounds to regenerate skin rather than scar tissue, which has obvious skin defects such as loss of dermatoglyph, abnormal perception, loss of hair follicle, etc., as compared to regenerated skin. Whether a hair follicle can regenerate is an important characterization of whether a wound heals or not as regenerating skin.
Aloe has a long history of application for wound repair, aloe polysaccharide is the main active substance of aloe, but the aloe polysaccharide extract has not shown the function of obviously promoting wound repair at present, and cannot be prepared into medicine.

In one embodiment of the present invention, referring to FIG. 1, an apparatus 1000 for promoting aloe polysaccharides to form a pervaporation membrane is shown in FIG. 1. The device consists of a low-temperature photoreaction tank 1 and a high-temperature film forming tank 2, wherein the corresponding sizes (the distance from a lamp 11 to a stirring tank 12 is G, the caliber of the high-temperature film forming tank 2 is D1, the height of the short side of the high-temperature film forming tank 2 is DL, the height of the long side of the high-temperature film forming tank 2 is DR, the height of a cylindrical section 121 is H, the height of a spherical bottom section 122 is S, the length of a stirring shaft 132 is L, the caliber of the stirring tank 12 is D) are G=80 cm, H=D=L=120 cm, S=22 cm, DL=D1=120 cm, DR=132 cm, aloe polysaccharide feed liquid is placed in the stirring tank 12, the lamp 11 is turned on to irradiate aloe polysaccharide feed liquid, and the stirring motor 131 is turned on at a rotating speed of 80 revolutions per minute, so that the aloe polysaccharide feed liquid fully flows and fully reacts for at least 24 hours.
The aloe polysaccharide feed solution reacted in the low temperature photoreaction tank 1 is pumped into the high temperature film forming tank 2, and it can be observed that aloe polysaccharide pervaporation film is continuously generated on the surface of aloe polysaccharide feed solution within 72 hours, and meanwhile, steam is continuously vaporized through the film, aloe polysaccharide feed solution is concentrated, and the effect of the aloe polysaccharide pervaporation film after film forming is shown in fig. 2. It should be noted that, fig. 2 is necessarily shown by using a color chart to reflect the actual film forming state and color of the aloe polysaccharide pervaporation membrane, and when a black-and-white chart is used in fig. 2, the film forming state and color of the aloe polysaccharide pervaporation membrane will become a petroleum-like look and feel, which is not completely in line with the film forming state of the aloe polysaccharide pervaporation membrane.
The high-temperature film forming tank 2 is designed with an inclined bottom, so that aloe polysaccharide feed liquid is uniformly distributed in the tank, when the aloe polysaccharide feed liquid enters the high-temperature film forming tank 2, the long-side evaporation amount is higher than the short side by the inclined bottom, so that fluid power is generated to enable the feed liquid to form directional flow towards one side of the long side of the surface of the feed liquid, and thus aloe polysaccharide pervaporation film generation is promoted, under the same condition, the aloe polysaccharide feed liquid treated by the low-temperature photoreaction tank 1 is placed in a round bottom and a flat bottom tank, the yield is obviously lower than that of the inclined bottom tank, if the aloe polysaccharide pervaporation film cannot be generated in the high-temperature film forming tank 2 under negative pressure, and the obtained product is observed by a scanning electron microscope (shown in fig. 3) and does not have the film characteristic.
In one embodiment of the present invention, the process for obtaining aloe polysaccharide feed liquid comprises the following steps:
Removing two ends of aloe leaf, soaking in pure water for 1-2 days, washing with water, and removing epidermis to obtain aloe gel to be ground.
Pouring aloe gel to be ground into the automatic gel grinding device for producing aloe gel, rotating the shearing motor at 1450r/min clockwise, and grinding for 15-20 min to obtain aloe polysaccharide feed liquid.
In this embodiment, a colloid milling method is adopted instead of a crushing method, so as to stimulate the parenchyma cells of aloe to secrete more polysaccharide through friction, so as to accelerate the release of polysaccharide in the extraction process and improve the extraction efficiency.
The aloe polysaccharide feed liquid and the aloe polysaccharide pervaporation membrane are respectively subjected to scanning electron microscopy imaging, and compared with the aloe polysaccharide feed liquid (refer to fig. 3 and 4), the aloe polysaccharide pervaporation membrane has shown plane continuity in microcosmic, namely membrane characteristics.
The aloe polysaccharide pervaporation membrane material is applied to the scalded wound of the SD rat, and after 28 days of wound molding, the tissue is subjected to HE staining and slicing, the results of which are shown in the following table (table one), compared with the CONTROL group (CONTROL), please refer to FIG. 5 (the abscissa of the right graph is two different experimental groups, CONTROL is the SD rat coated with aloe polysaccharide feed liquid, AVBER is the SD rat coated with aloe polysaccharide pervaporation membrane, the ordinate of the right graph is the hair follicle number of the SD rat, and three stars represent statistically significant differences), and the hair follicle number (Hair Follicle Number) of the SD rat (ABPA 2) coated with the aloe polysaccharide pervaporation membrane material is significantly improved, namely, the aloe polysaccharide pervaporation membrane has a significant effect on repairing hair follicles.
Table one results of the number of hair follicles of SD rats coated with aloe polysaccharide pervaporation membrane and the number of hair follicles of SD rats coated with aloe polysaccharide feed liquid:
In one embodiment of the present invention, the stirring tank 12 adopts an ellipsoidal bottom, and the temperature of the aloe polysaccharide feed liquid in the stirring tank 12 is controlled to be 4-15 ℃. The aloe polysaccharide feed liquid in the stirring tank 12 is generally controlled in temperature by a jacket circulation system, the jacket circulation system cools the aloe polysaccharide feed liquid outside the stirring tank 12, the jacket is a closed space arranged outside the stirring tank 12, a heat conduction channel is formed between the jacket and the wall of the stirring tank 12, and cooling medium (such as alcohol, cooling water and the like) circulates in the channel to cool the aloe polysaccharide feed liquid in the stirring tank 12, so that the temperature of the aloe polysaccharide feed liquid is maintained in a range of 4-15 ℃. The stirring tank 12 adopts an ellipsoidal bottom design, which is mainly used for promoting circulation and mixing of aloe polysaccharide feed liquid, and the ellipsoidal bottom design can reduce dead angles, so that the aloe polysaccharide feed liquid is more easily and uniformly stirred by the stirrer 13, local flow velocity difference in the mixing process is reduced, and the mixing efficiency is improved. In addition, the ellipsoidal bottom can reflect light rays to the feed liquid at multiple angles, so that the illumination efficiency is improved.
In one embodiment of the present invention, the illuminance of the lamp 11 at the illuminance monitoring point 3 in the agitation tank 12 should be not lower than 800 lumens. In order to monitor the illuminance at the illuminance monitoring point 3, an illuminance monitoring piece is arranged at the illuminance monitoring point 3, the illuminance monitoring piece can be a photodiode type illuminance sensor or a photoresistor type illuminance sensor, the invention is not limited to this, and the illuminance monitored by the illumination monitoring piece cannot be lower than 800 lumens, so that the photochemical reaction of aloe polysaccharide feed liquid can be ensured to have enough energy input.
In the invention, the low-temperature treatment is helpful for maintaining the stability and activity of aloe polysaccharide feed liquid, reducing the degradation or denaturation of aloe polysaccharide feed liquid and slowing down the degradation speed of aloe polysaccharide feed liquid. The stirring can ensure the uniform distribution of the components in the aloe polysaccharide feed liquid and ensure that the components form full vortex so as to reduce the local concentration difference, and the aloe polysaccharide feed liquid can be uniformly illuminated and uniformly contacted with air, so that the local degradation of the aloe polysaccharide feed liquid is avoided, and better conditions are provided for the subsequent membrane pervaporation process.
Proper illumination helps to trigger or accelerate photochemical reactions in aloe polysaccharide feed solutions. The aloe polysaccharide feed liquid reacts for at least 24 hours under the conditions of low temperature, stirring and illumination, the aloe polysaccharide feed liquid has higher hydrolysis degree and lower viscosity (under the condition of room temperature of 20 ℃, the viscosity of the aloe polysaccharide feed liquid which is not subjected to illumination treatment and the viscosity of the aloe polysaccharide feed liquid which is subjected to illumination treatment are found in the detection of the viscosity of the aloe polysaccharide feed liquid which is not subjected to illumination treatment, the viscosity of the aloe polysaccharide feed liquid which is not subjected to illumination treatment is 280.25 mpa.s, and the viscosity of the aloe polysaccharide feed liquid which is subjected to illumination treatment is 135.00 mpa.s, so that the viscosity of the aloe polysaccharide feed liquid can be obviously reduced by illumination).
In one embodiment of the invention, the temperature of the aloe polysaccharide feed liquid in the high-temperature film forming tank 2 is controlled to be 75-95 ℃. The temperature of the aloe polysaccharide feed liquid in the high-temperature film forming tank 2 is generally controlled by a jacket circulation system, the jacket circulation system heats the aloe polysaccharide feed liquid outside the high-temperature film forming tank 2, the jacket is a closed space arranged outside the high-temperature film forming tank 2, a heat conduction channel is formed between the jacket and the wall of the high-temperature film forming tank 2, and heating medium (such as heat conduction oil, water and the like) circulates in the channel to heat the aloe polysaccharide feed liquid in the high-temperature film forming tank 2, so that the temperature of the aloe polysaccharide feed liquid is maintained within the range of 75-95 ℃ to continuously form an aloe polysaccharide pervaporation membrane in the high-temperature film forming tank 2.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
