Carrageenan of Red Algae : Extraction, Antioxidant Activity, Rheology Characteristics, and Physicochemistry Characterization.

Carrageenan is an anionic sulfated polysaccharide that accounts for a high content of red seaweed . This paper focused on the extraction, optimization, and evaluation of antioxidant activity, rheology characteristics, and physic-chemistry characterization of β-carrageenan from . The extraction and the optimization of β-carrageenan were by the maceration-stirred method and the experimental model of Box-Behken.
