Description

Pectic Acid is a water-soluble polysaccharide derived from the partial hydrolysis of pectin, primarily composed of α-(1-4)-linked D-galacturonic acid units. This compound serves as a critical functional ingredient and analytical standard, valued for its gelling, thickening, and metal-chelating properties. It is essential for manufacturers and researchers in the food science, pharmaceutical, cosmetic, and biotechnology industries seeking consistent, high-purity materials for product development and quality control.

Application

• Food Industry: Used as a gelling agent, stabilizer, and texture modifier in jams, jellies, yogurts, and fruit-based products.
• Pharmaceuticals: Employed as an excipient in tablet formulations, a binding agent, and in controlled-release drug delivery systems.
• Cosmetics & Personal Care: Functions as a natural thickener, stabilizer, and film-forming agent in creams, lotions, and gels.
• Analytical & Research: Serves as a standard reference material for calibrating equipment and studying pectin structure, enzyme activity, and polysaccharide chemistry.
• Biotechnology: Utilized in microbial culture media and as a substrate for pectinase enzyme assays and production.
• Industrial Processes: Acts as a clarifying agent in beverage production and a chelating agent for metal ions in various applications.

Quality Control

Our Pectic Acid is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and reliability. We offer grades suitable for food, pharmaceutical, and research applications, with specifications aligning with industry expectations for purity and performance. A comprehensive Certificate of Analysis (COA), detailing parameters such as assay, galacturonic acid content, and loss on drying, is provided with each shipment to support your quality assurance protocols.

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, which can affect product quality and performance.
