| 摘要: |
| [目的]优化超声波辅助提取冷压榨桐粕中残余桐油的工艺条件。[方法]采用响应面法即中心组合(Box-behnken)实验设计,建立超声波辅助提取残油的二次多项数学模型,并分析液固比、提取温度、提取时间和超声功率等4个主要因素对残油得率的影响成分。[结果]响应面法统计分析预测的超声波辅助低温提取残油的较佳工艺条件为提取时间24.77 min,提取温度37.18℃,超声功率159.66 W,液固比(mL/g)3:1,预测残油得率为6.30%,验证实验显示在较佳条件下残油得率为(6.45±0.2)%;色谱分析结果显示,超声波辅助提取的桐油与传统溶剂提取成分一致。[结论]响应面法实验设计统计分析能有效预测超声波辅助提取残余油脂的较佳工艺条件,也进一步证明超声波辅助法提取的桐油品质良好。 |

| Abstract: |
| [Objective] The extraction conditions of residual Tung oil from cold pressing Tung meal by ultrasonic assistance were optimized.[Methods] Response surface analysis and simulation as a tool for design(Box-behnken) and optimization, and then quadratic multinomial mathematical model was established to optimize the process conditions of ultrasonic assisted extraction for residual Tung oil.Finally, the effects of four main factors were studied, such as ratio of liquid to solid, extraction temperature, extraction time and ultrasonic power.[Results] Through response surface analysis and simulation, the optimized conditions for extraction of residual Tung oil assisted by ultrasound were listed as follows:the extraction time of 24.77 min, the extraction temperature at 37.18℃, ultrasonic power of 159.66 W, liquid to solid ratio in 3:1(mL/g), where the predictive yield was 6.30%.The validation experiment showed that the actual yield was (6.45±0.2)%.HPLC analysis showed that the ultrasonic assisted extraction of tung oil was consistent with the traditional solvent extraction.[Conclusion] Experiment design using response surface method and statistical analysis can effectively optimize the process conditions of ultrasonic assisted extraction of residual oil from Tung meal and well predict the results, which further proves that Tung oil extracted by the ultrasonic assisted method can maintain a good quality. |
