摘要：

The frozen-hydrated/cryo-transmission electron microscopy technique has been used to observe polysaccharide aggregates in vitreous ice. Images of kappa-carrageenan in the helical state showed fairly large aggregates of a loosely intertwined network of thin rigid rods. Aggregates of agarose in the helical conformation were also visualised. In comparison with those of kappa-carrageenan, the strands of agarose were shorter and less rigid. This difference is discussed in terms of the current knowledge of the gelation of these polysaccharides.
