Abstract

A phase diagram of water—gellan gum systems was established using a common sample over a wide concentration range, from dry gellan to 0.1 % [(grams of gellan gum)/(grams of water) × 100%]. The phase-transition temperature was mainly measured by differential scanning calorimetry. Data obtained by various experimental techniques using the same sample are also cited. The glass transition, melting, liquid crystallization and the gel-sol transition were observed depending on the concentration and the temperature.
