Description

Maltotetraose is a linear tetrasaccharide composed of four glucose units linked by α-1,4 glycosidic bonds. This well-defined oligosaccharide serves as a valuable standard, substrate, and functional ingredient across research and industrial applications. It is particularly sought after by manufacturers and researchers in the food science, pharmaceutical, and biotechnology sectors for its specific enzymatic and physicochemical properties.

Application

• Enzymology & Biochemistry Research: Used as a specific substrate for studying the activity and kinetics of enzymes like amylases, glucoamylases, and other starch-degrading enzymes.
• Food & Beverage Industry: Functions as a mild sweetener, texturizer, and prebiotic dietary fiber to modulate gut microbiota and improve product stability.
• Pharmaceutical Excipient: Employed as a stabilizer, bulking agent, or carrier in solid dosage formulations and diagnostic reagent kits.
• Standard & Calibration: Essential as a high-purity chromatographic (HPLC, HPAEC-PAD) standard for the analysis and quantification of complex carbohydrate mixtures.
• Nutraceuticals & Functional Foods: Incorporated into supplements for its potential low-glycemic and prebiotic health benefits.
• Cosmetic Formulations: Acts as a natural humectant and moisturizing agent in skin and hair care products.

Quality Control

Our Maltotetraose is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and composition, suitable for research and industrial use. Certificates of Analysis (COA) documenting purity (by HPLC), moisture content, and specific optical rotation are provided to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
