Description

Glucomannan CAS NO 11078-31-2 is a high-molecular-weight, water-soluble polysaccharide derived from the konjac plant (*Amorphophallus konjac*). This natural hydrocolloid is valued for its exceptional thickening, gelling, and film-forming properties, making it a versatile functional ingredient. It is primarily sought after by manufacturers in the food, pharmaceutical, and nutraceutical industries for its role as a dietary fiber, stabilizer, and excipient.

Application

• Food & Beverage: Used as a thickener, gelling agent, and stabilizer in low-calorie foods, noodles, jellies, and beverages to improve texture and provide dietary fiber.
• Dietary Supplements & Nutraceuticals: A key ingredient in weight management and digestive health supplements due to its ability to promote satiety and support healthy cholesterol levels.
• Pharmaceuticals: Employed as a binder, disintegrant, and controlled-release matrix in tablet formulations and capsule shells.
• Cosmetics & Personal Care: Functions as a natural thickener, film-former, and moisturizing agent in creams, lotions, and masks.
• Industrial Applications: Utilized in water treatment processes, as a biodegradable film material, and in other specialty chemical formulations.
