Product Details

Potassium Alginate – Dual-Grade Biopolymer for Food & Agriculture Applications

Potassium Alginate is a naturally derived hydrocolloid extracted from brown seaweed (Laminaria spp.). Known for its excellent gelling, thickening, film-forming, and water retention properties, this biopolymer is widely used across industries—from clean-label functional foods to sustainable agricultural inputs.

Chibio Biotech provides both food-grade and agricultural-grade potassium alginate with customizable viscosity and gel strength to meet the needs of:

  • 🥤 Beverage, bakery, jelly, and fiber-rich foods

  • 🌾 Biofertilizers, soil conditioners, foliar sprays, and seed coatings


🌿 Product Overview

Potassium alginate works by forming stable gels in the presence of calcium or potassium ions, while simultaneously contributing to dietary fiber, water retention, and ion exchange capacity. In agriculture, it enhances nutrient uptake, supports microbial health, and improves soil water-holding—making it a sustainable material for modern precision farming.

At Chibio, our alginate is processed under GMP-aligned, ISO-certified production with strict control over heavy metals and microbiological content. With consistent purity and performance, it’s ideal for demanding commercial applications.
