Trehalose is a stable, nonreducing disaccharide with two glucose molecules linked in an α,α-1,1 configuration. It is obtained through enzymatic conversion of food-grade starch. It contains NLT 97.0% and NMT 102.0% of trehalose (C12H22O11 ), calculated on the anhydrous basis.IDENTIFICATION
A. Infrared Absorption
B.
Sample solution: 400 mg/mL of Trehalose
Analysis: Add 0.4 mL of a solution containing 1-naphthol in 95% alcohol (1 in 20) to 1 mL of the Sample solution. Gently add 2 mL of sulfuric acid to the solution.
Acceptance criteria: A violet color develops at the interface between the two solutions. C.
Glycine solution: 40 mg/mL of glycine
Sample solution: 40 mg/mL of Trehalose
Analysis: Add 1 mL of diluted hydrochloric acid to 2 mL of the Sample solution. Allow to stand for 20 min at room temperature. Add 4 mL of sodium hydroxide TS and 2 mL of Glycine solution to the Sample solution. Heat the solution for 10 min in boiling water.
Acceptance criteria: A brown color does not develop.ASSAY

REQUIREMENTS
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 an _,_-1,1 configuration. The powder is freely soluble or readily dispersible in water. Trehalose is typically used in its dihydrate form.
Function: Humectant; nutritive sweetener; stabilizer; thickener; texturizer.
Identification: Observe a sample with a light microscope at 50×. Trehalose is composed of colorless, rectangular crystals with a prismatic structure.
Assay: Not less than 98.0% Trehalose, calculated on a dry basis.
Color in Solution: Less than or equal to 0.100.
Lead: Not more than 0.1 mg/kg.
Loss on Drying: Not more than 1.5%.
pH of a 30% Solution: Between 4.5 and 6.5.
Residue on Ignition: Less than or equal to 0.05%.
Turbidity of a 30% Solution: Less than or equal to 0.050We also supply Trehalose Dihydrate and Anhydrous of BP Ph Eur grade.
