Carrageenan powder – natural gelling agent from seaweed | Food additives and thickeners
Carrageenan powder is a natural hydrocolloid extracted from red algae (Kappaphycus longifolia or Eucheuma chinensis), with the main active ingredient being a group of sulfated polysaccharides, mainly including kappa-, iota- and lambda-carrageenan. These molecules interact with proteins and water to form gels of various textures – from hard and crumbly kappa-type gels to soft and elastic iota-type gels. This makes carrageenan widely used as a gelling, thickening and stabilizing agent in multiple product categories such as dairy alternatives, meat products, jelly desserts and toothpaste.
Carrageenan demand continues to be strong due to the rise of plant-based and clean label trends. Carrageenan is available under the electronic code E407 and is used globally in developed and emerging food industries. Regulatory approvals in major markets such as the US, EU and Asia further underpin its safety and wide application. Our strength lies not only in providing food-grade carrageenan, but also in our precise control of gel strength, particle size and sulfate content, three core performance parameters that directly affect the quality of the final product.
Globally, the carrageenan market continues to grow, driven by demand for plant-based and clean-label ingredients. As consumers shift toward sustainable and natural products, carrageenan serves as a reliable alternative to synthetic additives.
At our facility, we specialize in producing high-purity carrageenan powder with optimized gel strength and rapid dissolution-qualities critical for dairy, meat, and beverage formulations. What sets us apart is our ability to tailor particle size and viscosity profiles to match specific production lines, a flexibility many standardized suppliers cannot offer.
Our OEM expertise allows clients to develop custom solutions-whether you need specific certification-compliant blends (e.g., EU, FDA, HALAL) or proprietary formulations for unique applications. We work closely with you to ensure consistency, scalability, and cost-efficiency-without compromising on performance. If you're looking for a carrageenan partner that combines technical precision with supply reliability, we're here to support your product innovation and production goals.
Why choose our carrageenan powder?
1. Higher gel strength, lower dosage
Our kappa carrageenan consistently achieves a gel strength of 1,200-1,500 g/cm² at 1.5% concentration (tested in 0.2% KCl solution at 20°C). This means a stronger gel at a lower dosage.
2. Ultra-low microbial count
Many competitors' carrageenan has a microbial content of less than 10⁴-10⁵ CFU/g, while our carrageenan is controlled low-temperature dried and double-stage sterilized to ensure a total colony count of less than 500 CFU/g.
3. Uniform particle size distribution
Our powder can pass through a 100 mesh sieve with a particle size distribution uniformity of >98%, preventing agglomeration, improving dispersion and flowability, and reducing problems during large-scale mixing or capsule filling.
4. Flexible Sulfate Range Customization
We offer customized sulfate levels between 20-30% and fine-tune to your target application - whether you need higher gel reactivity or a softer beverage taste.
