Trehalose is a non-reducing disaccharide composed of two glucose molecules with a molecular formula of C12H22O11. The structural formula of trehalose is α-D-glucopyranosyl-α-D-glucopyranosyl, often exists as dihydrate, and the molecular formula is C12H22O11·2H2O.
1. Food industry
In the food industry, considering the functions and characteristics of trehalose, such as non-reducing properties, moisturizing properties, anti-freezing and drying properties, high-quality sweetness, and energy sources, research and development of various uses are being carried out. Trehalose products can be applied to various foods and seasonings, etc., which can greatly improve the quality of food and increase the variety of food, and promote the further development of the food industry.
2. Pharmaceutical industry
Trehalose can be used as a stabilizer for reagent drugs and diagnostic drugs in the pharmaceutical industry. At present, starting from the functions and characteristics of trehalose, such as non-reducing properties, stability, protection of biological macromolecules, and energy supply, various applications are being explored. Using trehalose to dry antibodies such as vaccines, hemoglobulins, viruses and other biologically active substances does not need to be frozen, and can be revived after rehydration. Trehalose replaces blood plasma as biological products and stabilizers. It can not only be stored at room temperature, but also prevent pollution, thereby ensuring the storage, transportation and safety of biological products.
3. Cosmetics
Because trehalose has a strong moisturizing effect, sunscreen, anti-ultraviolet and other physiological effects, it can be used as a moisturizer, protective agent, etc. to be added to emulsions, facial masks, essences, facial cleansers, and can also be used as lipsticks and oral cleansers. , oral flavoring agent, sweetener, quality improver. Anhydrous trehalose can also be used in cosmetics as a dehydrating agent for phospholipids and enzymes, and its fatty acid derivatives are also excellent surfactants.
4. Crop breeding
Use biotechnology to introduce trehalose synthase gene into crops and make it express in crops, construct transgenic plants producing trehalose, cultivate new varieties of frost-resistant and drought-resistant transgenic plants, improve the cold and drought resistance of crops, and make them Appears fresh after harvesting and processing and retains its original flavor and texture.
Trehalose can also be used for seed preservation, etc. After using trehalose, it can effectively maintain the water molecules in the roots of seeds and seedlings, which is beneficial to crop sowing, with high survival rate, and at the same time protects crops from frostbite due to cold. It is of great significance to reduce production costs, especially the impact of the cold and dry climate in the north on agriculture.
