1. Application in molecular biology The protective effect of trehalose on dry biological products makes it useful in the field of biochemical products. If more products that can be stored and used at room temperature can be developed, the cost of biochemical products can be greatly reduced. At present, trehalose technology has been applied to the most unstable restriction endonucleases, so that they can be stored at room temperature for a long time without inactivation. This technology may also lead to the introduction of automated drying pools or dry PRC reactions. New biochemical tools such as kits.
2. The application prospects in agriculture. With the deepening of research and the development of genetic engineering technology, the establishment of genetically modified plants containing trehalose will not only improve the drought resistance of crops, but also make crops look fresher and more effective after harvesting and processing. Strong flavors such as sweet fruits, vegetables and other products. In addition, crops with high content of trehalose are closely related to their better freezing resistance. From this point of view, the establishment and development of drought-resistant plants may make important contributions to resisting drought and freezing disasters, transforming deserts, and greening barren and dry land.
3. The application in the pharmaceutical industry is mainly as a stabilizer of diagnostic reagents as reagents. For example, it is applied to the storage of internal organs for transplantation, the improvement and stabilization of lymphostimulants, biological agents, antibiotics, vitamins, enzymes, and various substances that are prone to inactivation. It can also be used as a sweetener, taste modifier, quality modifier and stabilizer in toothpaste, oral medicine, sugar-coated tablets, etc. At the same time, trehalose is used to dry the live vaccine, which is easy to preserve and can be said to be a good medical desiccant. It is extremely convenient and effective to use after re-watering. In addition, trehalose can not only be used for vaccine preservation, but also can stabilize hormones, blood and its components. Its practicability is also that it plays an important role in the preservation of biological high-tech products. For example, DNA restriction endonucleases used in genetic engineering are unstable and easy to inactivate under normal conditions.
4. In cosmetics: At present, trehalose derivatives are mainly used in cosmetics. In Japan, trehalose has been recognized as a new specification cosmetic raw material by the Ministry of Health because of its own moisture retention. For example, it can be used in skin cosmetics such as facial cleansers to inhibit dry skin; it can be used as a sweetener, taste modifier, and quality modifier for various compositions such as lipstick, oral freshener, and oral fragrance. In addition, anhydrous trehalose can be used in skin creams as a dehydrating agent for phospholipids and enzymes.
