Description

Polygalacturonic Acid is a high-purity, linear polymer of α-(1→4)-linked D-galacturonic acid units, serving as the primary structural component of pectin. This compound is valued for its excellent gelling, stabilizing, and chelating properties in aqueous systems. It is essential for manufacturers and researchers in the food science, pharmaceutical, cosmetic, and biotechnology industries seeking a well-defined pectic substance for product development and analytical applications.

Application

• Food Science & Technology: Used as a standard reference material for pectin analysis, in the study of gelation mechanisms, and for developing functional food textures.
• Pharmaceutical Research: Employed in drug delivery system development, particularly for colon-targeted formulations, and as a substrate for enzyme activity assays.
• Cosmetic Formulations: Acts as a natural bio-adhesive and film-forming agent in skincare and haircare products for enhanced texture and performance.
• Biotechnology & Enzymology: Serves as a specific substrate for polygalacturonase and pectinase enzyme activity testing and purification.
• Biomedical Materials: Investigated for use in wound dressings, hydrogels, and tissue engineering scaffolds due to its biocompatibility and biodegradability.
• Analytical Chemistry: Utilized as a chromatography standard and in calibration procedures for quantifying pectin content and structure.

Quality Control

Our Polygalacturonic Acid is produced under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for research and industrial applications. While specific grades can be tailored, our standard material is characterized for identity, assay, and impurity profile. A Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment.

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). Keep the container tightly sealed in a dry environment to prevent moisture absorption and caking.
