Studies of the deposit concentration and crystal shape of Monoammonium Glycyrrhizinate (MG) were made. For the purpose of observation of basic data for batch crystallization experiment, the deposit concentration was measured at different mixtures (75-25, 80-20 and 85-15) vol % of ethanol-water. To obtain the relation between MG purity, AT (difference of the temperature of a fixed deposit concentration solution and crystallization temperature) and crystal shape, the shape of produced crystals was observed at different MG purity and different ΔT (ΔT=1, 5, 10, 20, 30 and 40℃) by a controlled batch crystallization. In the case of MG purity 68.8 wt %, rectangle crystal shape was observed. In the case of MG purity 50 wt %, the crystal shape changed from rectangle to octagon and hexagon-like. In the case of MG purity 35.2 wt %, lozenge crystal shape was observed. It was found that the degree of purity and ΔT influenced markedly the shape of produced crystals.
