摘要
目的通过加入表面活性剂,提高黄原胶发酵产量。方法初步筛选6种常用的表面活性剂,优选两种优势互补的表面活性剂进行加入量、加入时间、加入比例的优化,采用单因素和正交试验得到最佳工艺参数。结果吐温20、曲拉通X-100协同使用效果最好,发酵0 h加入0.06%曲拉通X-100,48 h加入0.09%吐温20,黄原胶产量提高42.0%。结论表面活性剂能提高黄原胶发酵产量。
Purpose To improve the fermentation yield of xanthan gum by adding surfactants. Meth- ods Six surfactants were tested as accelerants,and two were chosen to optimize the addition dosage, addi- tion time and addition ratio respectively. Monofactorial experiments and orthogonal test were investigated to find out the combined effect of the two kinds of surfactants. Results Tween-20 and Triton X-100 were the best,and by adding 0.06% Triton X-100 in the beginning of fermentation,adding 0.09% Tween-20 at 48 h in the fermentation period,the yield of xanthan gum could be improved 42.0%. Conclusion Surfactants can promote xanthan gum production.
