采用超高压技术提取番茄渣中番茄红素,在单因素试验基础上,采用正交试验法对番茄渣中番茄红素的超高压提取工艺进行优选,选用L_9(3~4)进行正交试验,以番茄红素提取率为指标,考察超高压压力、保压时间、固液比、提取次数对番茄红素提取率的影响.得到的最佳工艺条件为超高压压力300MPa、保压时间5min、固液比1:10(g/mL)、提取次数3次.番茄红素的提取率可达83.2%.超高压提取方法得率高、提取时间短,是一种提取番茄渣中番茄红素的适宜方法.

As a novel technique which helps achieve the extraction of hioactive substances from botanic materials under room temperature,ultra high pressure(UHP)extraction is an attractive alternative to conventional techniques that include microwave extraction,nitrasonic extraction,supercritical extraction,etc due to time saving,low energy consumption and impurity dissolution,and high extraction efficiency.Therefore,this technique was also applied to the extraction of lycopene from tomato skin in this study.The optimal UHP extraction process was investigated for maximizing lycopene yield using orthogonal array design based on single factor experiments,where the effects of UHP pressure level,holding time,solid/liquid ratio and extraction number on lycopene yield were examined.Results showed that a maximum lycopene yield of 83.2% was obtained through the triplicate extraction at a solid/liquid ratio of 1:10(g/mL)enhanced by UHP treatment at 300 MPa pressure level held for 5 min.
