Description

Melibiose is a disaccharide sugar composed of galactose and glucose, widely recognized for its role as a biochemical research tool and a potential functional food ingredient. Its significance lies in its specific enzymatic hydrolysis by α-galactosidase, making it a critical substrate for diagnostic assays and enzyme activity studies. This high-purity compound is essential for researchers in pharmaceutical development, food science, and microbiology, as well as for manufacturers exploring novel prebiotic formulations.

Application

• Biochemical Research: Used as a specific substrate for α-galactosidase enzyme assays in diagnostic kits and metabolic studies.
• Pharmaceutical Development: Serves as a reference standard and intermediate in the synthesis of complex carbohydrates and glycoconjugates.
• Food & Beverage Science: Investigated as a potential prebiotic and low-glycemic sweetener in functional food product development.
• Microbiology & Fermentation: Utilized in microbial culture media to study carbohydrate metabolism and as a carbon source in fermentation processes.
• Diagnostic Reagents: A key component in reagents for the detection of Fabry disease and other enzymatic deficiency disorders.
• Cosmetic Research: Explored for its humectant and skin-conditioning properties in advanced cosmetic formulations.

Quality Control

Our Melibiose is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including HPLC purity, optical rotation, and residual solvent analysis, to meet the rigorous demands of research and development. Certificates of Analysis (COA) are available for every batch upon request, confirming compliance with in-house specifications suitable for laboratory and pilot-scale use.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture.
