Product Name: Trehalose
CAS No.: 6138-23-4
Molecular Formula: C12H22O11.2H2O
Molecular Weight: 378.33
Description: Trehalose occurs as a nonhygroscopic, white, crystalline powder. It is obtained through enzymatic conversion of food grade starch into a stable, nonreducing disaccharide with two glucose molecules linked in a α, α-1, 1 configuration. The powder is freely soluble or readily dispersible in water. Trehalose is typically used in it’s dehydrate form. Trehalose has about 45% the sweetness of sucrose at concentrations above 22%, but when the concentration is reduced, its sweetness decreases more quickly than that of sucrose.
