| 摘 要： | 以西藏灵菇发酵液为材料,通过高压脉冲电场技术研究了辅助提取胞外多糖的最优条件。结果表明:高压脉冲电场辅助提取乳酸菌胞外粗多糖的最佳技术条件是:电场强度为40kV/cm,脉冲数为8,pH值为7。影响胞外多糖提取的因素的主次顺序为电场强度>pH>脉冲数,其中电场强度对胞外多糖提取具有显著性影响(α<0.05)。优化处理后胞外多糖提取数量比对照组提高了84.30%。

| Abstract: | The high intensity pulsed electric field-assisted extraction technique was used to optimize the conditions of exopolysaccharides(EPS) extraction in Tibetan spiritual mushroom broth.The results show that the optimal conditions of this extraction technique are: electric field intensity of 40 kV/cm,number of pulses of 8,and pH of 7.These factors affect the EPS extraction in the order of electric field intensity > pH > number of pulses.The influence of the electric field intensity on EPS extraction is significa... |
