摘要:
以银条为原料，采用超声波辅助法提取果胶，在单因素试验的基础上，通过正交实验研究了超声功率、超声时间和液料比对果胶得率的影响，同时对该法提取果胶的理化性质进行了初步分析。结果表明：银条果胶的最佳提取工艺为超声功率300 W，液料比40∶1 (V∶W)，超声时间20 min，在此条件下银条果胶得率为20.46%；所得银条果胶的半乳糖醛酸含量为43.80%，果胶酯化度为55.56%，果胶的蛋白含量为3.63%。
Abstract:
Taking Stachys floridana Schuttl.ex Benth as material，pectin was extracted by ultrasonicassisted extraction.The effect of ultrasonic power，ultrasonic time and ratio of water to material on the yield of pectin were investigated by orthogonal tests based on single factor experiment，and then physicochemical properties of pectin were further studied.The results showed that the optimum extraction conditions were determined as ultrasonic power 300 W，ultrasonic time 20 min，ratio of liquid to material 40∶1 (V∶W)；under these extraction conditions，the yield of pectin was 20.46%.Galacturonic acid content，the protein content and esterification degree in pectin gained under the optimal conditions were 43.80%，3.63% and 55.56% respectively.
