Description

Maltotriose CAS NO 1109-28-0 is a trisaccharide sugar composed of three glucose units linked by α-1,4 glycosidic bonds. This high-purity oligosaccharide is valued for its precise structure and consistent performance as a biochemical standard and a functional food ingredient. It serves as a critical reagent and intermediate for manufacturers and research institutions in the pharmaceutical, food science, and biotechnology sectors.

Application

• Biochemical Research & Standard: Used as a precise reference standard in chromatography (HPLC, TLC) and enzymatic assays to quantify and identify other carbohydrates.
• Pharmaceutical Excipient: Functions as a stabilizer, bulking agent, or sweetener in solid dosage formulations and diagnostic kits.
• Food & Beverage Industry: Acts as a mild sweetener, texture modifier, and prebiotic fiber in functional foods, sports nutrition, and infant formula.
• Enzymology Studies: Serves as a specific substrate for studying the activity and kinetics of enzymes like α-amylase and glucoamylase.
• Microbial Fermentation: Provides a defined carbohydrate source for the cultivation of specific microorganisms and in fermentation process optimization.
• Cosmetic Formulations: Utilized as a humectant and skin-conditioning agent in personal care products due to its moisture-binding properties.

Quality Control

Our Maltotriose is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial applications. Certificates of Analysis (COA) detailing purity, residual solvents, and other critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product should be stored in a cool, dry place at a controlled room temperature (15-25°C). For long-term stability, consider storing under desiccant or in a nitrogen atmosphere after opening.
