application | this raw material has a wide range of uses. its main function is to be used as a lubricant to make the skin rich in luster, soft feeling but no oil film. In addition, it is also a liquid carrier with excellent performance, which can accommodate more materials, such as the preparation of beauty and cosmetics, and some waxes and resins can also be used as admixtures and solubilizers. at present, the application and research of aloe in life practice have the following aspects: 1. the research in medical clinic: lucang has antibacterial, anti-inflammatory and anti-tumor effects. the experiment found that the onion quinone compound in reed extract has antibacterial effect on bacteria and mold, for example, it has strong antibacterial effect on Staphylococcus aureus, Aspergillus oryzae, Candida and Trichoderma. After subcutaneous implantation of malignant invasive sarcoma cells in female mice and injection of ACM in aloe vera gel, it was found that tumor cells degenerated and necrotic, and the survival rate of mice was effectively improved. 2. application in cosmetics industry: but with the progress of science and technology, our life is also undergoing earth-shaking changes, which also brings the opportunity of the times for the renewal of aloe industry. Some documents have pointed out that aloe contains polysaccharides and amino acids. Sending some mucus can be used as a natural moisturizer, which has the function of restoring skin collagen. It can keep the skin smooth and moist, make it elastic, and then play a role in delaying aging. Therefore, the cosmetics containing aloe ingredients on the market, such as aloe cream and aloe facial cleanser, are all developed based on this effect. 3. Application in food industry: Aloe vera is not only popular in China, but also highly recognized by the public in Japan. The main varieties of aloe in Japanese planting areas are aloe vera. Some documents point out that Japanese people sometimes add dried aloe powder directly to milk or other foods and use it in aloe foods in my country. The current products on the market include aloe yogurt, Aloe vera tea, aloe jam and Luyun drinks. |
production process | supercritical fluid CO2 extraction technology extracts aloe vera oil to compress the gas above the critical point to make it a supercritical fluid (SCF). the diffusion coefficient of supercritical fluid in solute is (0.01~1)* 10- 6 m2/s, however, the diffusion coefficient of liquid in solute (0.0004~0.003)* 10- 6 m2/s shows that the diffusion coefficient of supercritical fluid is hundreds of times that of liquid. Using the special transfer properties of supercritical fluids, supercritical fluids are used in chemical separation processes such as extraction, crystallization, chromatographic analysis, drying, and some chemical reactions. Supercritical fluid CO2 extraction technology is suitable for extracting fat-soluble substances in aloe, such as aloe oil, plant alkali, aloin and other volatile trace components in aloe . The use of supercritical fluid CO2 to extract bioactive substances in aloe vera has the main advantages of operating at room temperature and can retain the activity of biological substances in aloe vera. It is especially suitable for extracting heat-sensitive, easily oxidized and volatile components in aloe vera. The extraction rate is relatively high, the extract is easy to separate, and the energy consumption is low. Its main disadvantage is that the extraction operation is carried out under high pressure conditions, the equipment is complex, and the equipment cost is high. |
composition | aloe vera oil contains carotenoids and aloe-emodin and their derivatives, and its color is light yellow-green turbid liquid. the main component is mixed fatty acid glycerin, oleic acid (cis-9-octadecenoic acid) accounts for the main component. Aloe vera oil is a mixture of triglycerides, melting point and freezing point is a temperature range, generally between 40~50 ℃, the specific gravity is smaller than water, decreases with the increase of molecular weight, and increases with the increase of unsaturation. The refractive index of aloe oil increases with the increase of molecular weight and increases with the increase of double bond. Conjugated double bonds exist, which have a higher refractive index than similar non-conjugated double bond compounds. |
