Trehalose is a disaccharide widely present in animals, plants and microorganisms in nature. It is a non-reducing sugar formed by 2 glucose through α,α-1,1-glycosidic bonds. Biosynthesis of trehalose is to store energy And absorb water, used to fight against freezing and lack of water. Trehalose dihydrate precipitated from dilute ethanol is a colorless or white orthorhombic bisphenoidal crystal with a sweet taste. Used as a food additive (water retention) and sweetener, the sweetness is equivalent to 45% of sucrose. Since it is not a reducing sugar, Maillard reaction browning does not occur when heated with amino acids and proteins.
Main Purpose
Because the sugar has unique biological functions, it can effectively maintain the stability and integrity of intracellular biofilms, proteins, and active peptides in adversity. It is praised as the sugar of life and can be widely used in biological agents, medicine, and food , health products, fine chemicals, cosmetics, feed and agricultural science and other industries.
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. Functional properties of trehalose and its application in food:
(1) Prevent starch aging
(2) Prevent protein denaturation
(3) Inhibit lipid oxidation and deterioration
(4) Correct taste
(5) Keep vegetables and meat tissue stable and Fresh-keeping effect
(6) Long-lasting and stable energy source.
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.
