目的制备番茄红素油树脂微囊，并对其稳定性进行考察。
ObjectiveTo prepare lycopene oil resin microcapsule and study its stability.
采用超临界CO 2流体萃取技术，对番茄红素油树脂中的有机溶剂残留进行反向萃取。
The organic solvent residue of lycopene oleoresin was removed with reverse supercritical CO2 fluid extraction under various combinations of pressure, temperature, flow rate of CO2 and extraction time.
结果表明：乙酸乙酯热回流处理后，6%番茄红素油树脂中顺式异构体占比高于90%番茄红素中顺式异构体占比；
The results showed that proportion of cis-isomers in 6% oleoresin samples were higher than that in 90% lycopene samples after ethyl acetate reflux.
