Description

D-(+)-Maltose Monohydrate is a high-purity, crystalline disaccharide sugar derived from starch hydrolysis. This compound serves as a critical reducing sugar and a versatile carbon source in biochemical and industrial processes. It is essential for manufacturers in the pharmaceutical, food & beverage, and biotechnology sectors, where consistent quality and reliable supply are paramount.

Application

• Pharmaceutical Excipient: Used as a stabilizer, bulking agent, and sweetener in tablet formulations and lyophilized (freeze-dried) products.
• Microbiology & Cell Culture: Serves as a defined carbon and energy source in fermentation media and cell culture applications.
• Food & Beverage Industry: Functions as a sweetener, texture modifier, and browning agent in baked goods, confectionery, and brewing.
• Diagnostic Reagents: A key component in clinical chemistry kits for the determination of enzymatic activity, such as amylase.
• Biochemical Research: Employed as a standard in chromatography and as a substrate for enzyme studies (e.g., α-glucosidase).
• Animal Feed Supplement: Provides a readily digestible energy source in specialized nutritional formulations.

Quality Control

Our D-(+)-Maltose Monohydrate is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for demanding applications. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, optical rotation, and impurity profiles. Specifications can be aligned with Food Chemical Codex (FCC) or other relevant pharmacopeial guidelines upon request.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking and degradation.
