Abstract: D-arab sugar is the intermediates of a variety of functional sugar, and  its purity level has an important effect on the functional sugar conversion rate. Therefore, getting high purity D-arab sugar is particularly important. In this study, factors such as crystallization temperature, stirring rate and ion content in crystalline liquid were measured. Results showed that the optimum condition was as follows:under the gradient cooling form, stirring speed was 5 r/min, and ion content was under 100 μs/cm, then D-arab sugar crystals purity can reach 99.8%. Results laid a foundation for the efficient conversion of functional sugar.
