摘要: 本实验研究了超临界CO2工艺参数对成熟番茄中番茄红素、β-胡萝卜素和叶黄素溶解度的影响。提取压力范围为10~45MPa,温度范围为40~80℃。操作参数不同,番茄红素、β-胡萝卜素及叶黄素在超临界流体中的溶解度不同。实验证明,在35MPa、70℃时,提取物中番茄红素含量可达80.25%,从而省去了番茄红素的纯化过程。

Abstract: This work described the influence of some operative parameters of supercritical carbon dioxide extraction employed for the separation of lycopene and β-carotene,lutein from the pulp and skins of ripe tomatoes.The extractions were conducted at pressures and temperatures ranging from 10 to 45 MPa and 40 ℃ to 80 ℃,respectively.Lycopene and β-carotene,lutein showed a different solubility in the supercritical fluid depending on processing parameters.With a proper choice of operative parameters,it has been possible to obtain a product that contained 80.25% lycopene.Therefore,purification processing can be avoided.
