Abstract
Carrageenin was fractionated with potassium chloride and by successive extractions at elevated temperatures. Measurements were made of sulphate content, optical rotation, gel strength, intrinsic viscosity, sedimentation rate, and ionic mobility. The results indicated three components extractable at 30 °C., 60°C., and 100–120 °C. The 60 °C. extract had a high gel strength while the components extracted at 30 °C. and 100–120 °C. showed low gelling tendencies. The two non-gelling components were concentrated in the supernatant liquid when fractionated with potassium chloride.Keywords
