摘要： Dintzis[1]曾用经典光散射法测得经90℃、4mool/L尿素处理3h的黄原胶分子量为2×106,不加热的分子量为13×106和50×106,但未知确切数据。

Abstract: The methods of ultracentrifugation, measuring molecular length by transmissive electron-microscope and small angle laser light-scattering were used to determine the molecular weight of self-made xanthan. The molecular weight measured by the three methods above are 2. 5×106, 6×106-2. 5×106 and 2. 36×106 dalton, respectively. Three results are well consistent with each other.
