Product Description

Semi-Refined Carrageenan (SRC), also known as Processed Eucheuma Seaweed (PES), is a cost-effective hydrocolloid extracted from red seaweed through alkaline treatment without complete removal of cellulose. It offers excellent thickening, gelling, and stabilizing properties, making it ideal for applications where performance and cost efficiency must be balanced.

Compared with refined carrageenan, SRC retains natural fiber components, providing strong gel strength and good water-binding capacity, especially in meat and pet food systems.
