Import Carrageenan — Buy in Bulk from Supplier in China

Carrageenan from Dawndawn Biotech is a natural hydrocolloid extracted from red seaweed, supplied as a fine, off-white to beige powder. The product functions as a gelling, thickening and stabilising agent in aqueous systems, with typical viscosity values between 5 and 800 mPa·s at 1.5 % concentration and 75 °C, depending on grade. It is soluble in hot water and forms thermoreversible gels upon cooling, making it suitable for formulations requiring heat stability and controlled texture.

The material is available in kappa, iota and lambda types, each offering distinct gel characteristics. Kappa carrageenan produces strong, brittle gels with potassium ions, iota forms elastic gels with calcium ions, and lambda remains non-gelling but provides high viscosity. Typical moisture content is 10 - 12 %, ash content ≤ 5 % and protein ≤ 3 %, with a pH range of 7 to 11 for a 1 % solution. Industry-standard mesh sizes range from 80 to 100, ensuring consistent particle distribution for industrial processing.

Food manufacturers use this carrageenan in dairy alternatives, desserts, sauces and meat products to improve mouthfeel and prevent syneresis. It is also employed in cosmetics for lotion stabilisation and in pharmaceuticals as a suspending agent. Suppliers typically offer 25 kg multiwall paper bags with polyethylene liners for bulk shipments. Buyers should confirm the exact grade and mesh size for their application, as performance varies by type and particle fineness.

Dawndawn Biotech operates from Hemu Road in Hangzhou, Zhejiang Province, China. The supplier holds a Harbor trust tier, indicating a verified business presence, though the listed response rate and average response hours are currently unavailable. The company specialises in food additives, with carrageenan as a core product line for industrial and commercial buyers.

The profile does not state certifications, production capacity, or client details, so buyers must confirm compliance with ISO, FDA, or other relevant standards directly. Dawndawn Biotech’s focus appears to be on bulk supply, but specific minimum order quantities, lead times, and incoterms are not provided in the listing. Buyers should request these trade terms to assess feasibility for their procurement needs.
