【摘要】 根据微生物多糖分子链长,空间结构复杂的特点,研究了Gellan Gum酰基含量测定时的样品量、反应时间、反应温度、反应方式及体系pH的影响,得出最佳的反应条件为:pH14,25℃~30℃,放置12h以上;或50℃保温震荡30min。两法的标准偏差分别为0.0082和0.0063。更多还原

【Abstract】 The solution of gellan gum had a high viscosity. The determination of the quality of acyl was difficulty. The effort on some parameter such as: the weight of sample, the reaction of time, the temperature of reaction, the way of reaction and pH were studied and got better conditions as followings: (1) above 12hr at pH= 14, 25℃ -30℃;(2) on oscillator at 50℃ for 30min. The standard errors were 0.0082 and 0.0063, restectively.更多还原
