摘  要：
采用高压脉冲电场技术辅助提取番茄皮渣中的番茄红素。通过单因素试验和正交分析试验确定提取的最佳工艺参数,并与常规有机溶剂提取法、超声波辅助提取法、微波辅助提取法进行了对比试验。结果表明:当以乙酸乙酯为提取溶剂、电场强度为30kV/cm、液料比为9mL/g、脉冲数为8、温度为30℃、单次提取时,番茄红素提取率能达到96.7%,是常规有机溶剂法的2.4倍、是微波辅助法的1.23倍、是超声波辅助法的1.04倍,且处理时间短(16μs)。因此,高压脉冲电场辅助提取法是一种新型快速的番茄红素提取方法。

摘  要：
The high intensity pulsed electric fields (HIPEF) method was assisted in extracting lycopene from tomato residual.The optimal processing conditions were acquired by the single-factor experiment and the orthogonal experiment,and then comparative extraction tests were performed among the HIPEF-assisted extraction method,the organic solvents extraction method,the ultrasonic-assisted extraction method,and the microwave-assisted extraction method.The results show that with the shortest time (16 μs),the highest extraction rate 96.7% by lycopene was achieved under the following conditions:extraction solvent being ethyl acetate,electric field intensity 30 kV/cm,electric pulse number 8,liquid-stuff ratio 9 mL/g,temperature 30℃ and single-stage extraction.Extraction rate of HIPEF-assisted extraction method is 2.4 times as much as that of the organic solvents extraction method,1.04 times of the ultrasonic-assisted extraction method,and 1.23 times of the microwave-assisted extraction method.HIPEF-assisted extraction method is proved to be a new and fast way to extract lycopene from the tomato residual.
