摘要
为从理论上揭示微波辅助萃取蓝莓花青素的传递机理,基于固液传质理论和Fick第一定律,建立微波辅助萃取蓝莓花青素的动力学模型,并对微波功率和萃取时间进行动力学模拟。结果表明蓝莓花青素残留量随萃取时间和微波功率增加呈降低趋势。花青素残留量试验值与模拟值接近,决定系数(R2)均在0.92以上。表明所建立的微波辅助萃取蓝莓花青素动力学模型可靠和合理,通过该模型可以预测不同萃取时间和微波功率下花青素含量。研究结果为获得高得率、低降解率的微波辅助萃取蓝莓花青素的工艺提供理论依据。
A kinetic model of microwave-assisted extraction of anthocyanins from blueberry was established based on solid-liquid mass transfer theory and Fick’s First Law to study the transfer mechanism of microwave-assisted extraction of blueberry anthocyanins.Microwave power and extraction time were also simulated.The results showed that the content of anthocyanins decreased with the increase of extraction time and microwave power.The determination coefficient(R2)of anthocyanins residue was above 0.92.The results showed that the kinetic model was reliable and reasonable,and anthocyanins content under different extraction time and microwave power could be predicted by the model.The results provide a theoretical basis of microwave-assisted extraction of anthocyanins from blueberry with high yield and low degradation rate.
