[Trehalose Supply] Trehalose has these four properties

Trehalose, also known as trehalose and muscimol, is a non-reducing disaccharide composed of two glucose molecules. It is easy to crystallize and soluble in water. , hot ethanol, glacial acetic acid, insoluble in acetone.

Trehalose has the following four properties:

　1. Stability and safety

Trehalose is the most stable type of natural disaccharide. Since it is non-reducible, it has very good stability against heat, acid and alkali. When coexisting with amino acids and proteins, Maillard reaction will not occur even when heated, and it can be used to process foods and beverages that require heating or high-temperature preservation. Trehalose enters the small intestine of the human body and is decomposed into two molecules of glucose by trehalase, which is then used by the body’s metabolism. It is an important source of energy and is beneficial to human health and safety.

2. Low hygroscopicity

Trehalose Also has low moisture absorption properties. If trehalose is placed in a place with a relative humidity of more than 90% for more than 1 month, trehalose will hardly absorb moisture. Due to the low hygroscopicity of trehalose, applying trehalose to this type of food can reduce the hygroscopicity of the food, thereby effectively extending the shelf life of the product.

3. High glass transition temperature

Trehalose has a higher glass transition temperature than other disaccharides, as high as 115°C. Therefore, when trehalose is added to other foods, it can effectively increase its glass transition temperature and make it easier to form a vitrified state. This property, combined with trehalose’s process stability and low hygroscopicity, makes it a high protein protectant and ideal spray-dried flavor preserver.

4. Non-specific protective effect on biological macromolecules and organisms

Trehalose is a typical stress metabolite formed by organisms in response to changes in the external environment, protecting the body against harsh external environments. At the same time, trehalose can also be used to protect DNA molecules in organisms from damage caused by radiation; exogenous trehalose also has a non-specific protective effect on organisms. Its protective mechanism is generally considered to be that the part of the body containing trehalose strongly binds water molecules and shares bound water with membrane lipids or trehalose itself functions to replace membrane-bound water, thus preventing the denaturation of biological membranes and membrane proteins.
