Detailed Product Description

Carrageenan is extracted from many species of red seaweeds. The process begins with harvesting, followed by drying, cleaning, bagging or bailing. Once in the factory, the seaweeds are sorted, tested for quality and stored.

Before being processed, they are hand-inspected, then washed to remove dirt and marine organisms, and then subjected to hot alkaline extraction. When the carrageenan is dissolved, it is clarified through conventional filtration and is then concentrated by membrane ultrafiltration.

The carrageenan is precipitated by alcohol or potassium chloride to separate it from soluble impurities. This is followed by drying and grinding to appropriate particle size. The carrageenan powder is blended and standardized to customer specifications before shipment.
