Description

Isomaltose is a disaccharide sugar composed of two glucose molecules linked by an α-1,6-glycosidic bond, distinct from the more common α-1,4 linkage found in maltose. This unique structure makes it a valuable intermediate and functional ingredient in advanced biochemical research and specialty food applications. It is particularly sought after by manufacturers in the pharmaceutical, nutraceutical, and food science industries for its role as a prebiotic, a low-glycemic sweetener, and a standard for analytical chromatography.

Application

• Pharmaceutical Research & Development: Used as a biochemical standard, reference compound, and intermediate in the synthesis of complex carbohydrates and glycoconjugates.
• Nutraceutical & Functional Food Production: Incorporated as a prebiotic fiber to promote gut health and as a low-glycemic index sweetener in specialized dietary products.
• Food Science & Analytical Chemistry: Serves as a critical calibration standard in High-Performance Liquid Chromatography (HPLC) and other analytical methods for sugar analysis.
• Enzymology & Metabolic Studies: Employed as a specific substrate for studying the activity of enzymes like isomaltase and for research into carbohydrate digestion and metabolism.
• Cosmetic Formulations: Utilized as a mild humectant and skin-conditioning agent in advanced personal care products.

Quality Control

Our Isomaltose is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for research and industrial applications. A comprehensive Certificate of Analysis (COA), detailing parameters such as assay, optical rotation, and impurity profiles, is 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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture.
