Description

Curdlan is a high-purity, high-molecular-weight β-1,3-glucan polysaccharide produced through microbial fermentation. This unique biopolymer is valued for its ability to form resilient, thermally irreversible gels upon heating, providing exceptional texture and stability in formulated products. It is an essential functional ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking natural, label-friendly hydrocolloids with superior gelling properties.

Application

• Food Industry: Used as a gelling agent, thickener, and stabilizer in products like noodles, tofu, processed meats, and low-calorie jellies to improve texture, water retention, and freeze-thaw stability.
• Pharmaceuticals: Employed as an excipient in controlled-release drug delivery systems, tablet binders, and wound dressing materials due to its biocompatibility and gel-forming characteristics.
• Biomedical Research: Serves as an immune-modulating agent and a substrate for studying β-glucan receptors and related biological pathways.
• Personal Care & Cosmetics: Functions as a film-forming agent, viscosity modifier, and texture enhancer in creams, lotions, and masks.
• Industrial Applications: Investigated for use in biodegradable films, encapsulation matrices, and as a flocculant in water treatment processes.
