Description

Konjac Glucomannan is a high-molecular-weight, water-soluble polysaccharide derived from the tuber of the *Amorphophallus konjac* plant. This natural hydrocolloid is prized for its exceptional thickening, gelling, and film-forming properties, making it a versatile functional ingredient. It serves as a critical texturizer, stabilizer, and dietary fiber source across the food, pharmaceutical, and nutraceutical industries. Its unique ability to form high-viscosity solutions at low concentrations addresses key formulation challenges in product development.

Application

• Food & Beverage: Used as a thickener, gelling agent, and stabilizer in noodles, vegan meat alternatives, sauces, dairy products, and low-calorie foods.
• Dietary Supplements & Nutraceuticals: A key ingredient in weight management and appetite control products due to its high fiber content and ability to promote satiety.
• Pharmaceuticals: Employed as a binder, disintegrant, and controlled-release matrix in tablet formulations, and as a bulk-forming laxative.
• Cosmetics & Personal Care: Functions as a film-forming agent, thickener, and moisturizer in creams, lotions, masks, and hair care products.
• Industrial Applications: Utilized in biodegradable films, edible coatings, and as a flocculant in water treatment processes.
• Pet Food: Acts as a texturizer and source of soluble fiber in premium pet food formulations.

Quality Control

Our Konjac Glucomannan is produced under strict quality management systems to ensure batch-to-batch consistency and compliance with international standards. We offer grades compliant with FCC (Food Chemicals Codex) and Food Grade specifications, with options for Kosher and Halal certification. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing purity, viscosity, microbiological limits, and heavy metal content, available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
