Trehalose is a disaccharide widely distributed in plants, animals and microorganisms in nature. It is a non-reducing sugar formed by two glucoses through a, a-1, 1-glycoside bond. According to its chemical structure, trehalose can be written as alpha-D-glucosyl-(1_1) -alpha-D-glucoside, in addition to alpha, Beta-type of new trehalose and beta, Two isomers of beta - isomeric trehalose are rare in nature. Trehalose dihydrate precipitated from dilute ethanol is a colorless or white rhombic biconical crystal with sweet taste. Used as food additives and sweeteners, sweetness is equivalent to 45% of sucrose. Because it is not a reducing sugar, Maillard reaction browning does not occur when it is co-heated with amino acids and proteins.

Trehalose, also known as alpha, alpha-trehalose, alpha-D-glucopyranoyl-alpha-D-glucopyranoside, Mycose, is a non-reducing disaccharide formed by dehydration and condensation of hemiacetal hydroxyl groups on the heterocarpic carbon atom (C1) of two molecules of D-glucose. It is mainly divided into three kinds: alpha, alpha trehalose, alpha, beta trehalose, beta, beta trehalose and so on. It can also be synthesized in mould, algae, dry yeast, ergot and so on. It has the special function of preserving biological activity, protecting the structure of cell membrane and protein effectively, keeping the cells moist under abnormal conditions, such as high temperature dehydration (drying, high osmotic pressure), freezing, and preventing the loss of nutrients and cell damage caused by dehydration. To stabilize the structure of biofilms and proteins, it has been used internationally to protect genetic engineering enzymes, viruses, vaccines, antibodies, protein factors, nucleic acids and other biological active substances as stabilizers and protectants. It has a wide range of applications in food, health care products, cosmetics, medicine, molecular biology and agriculture. The application prospect.
