Abstract The extraction of lycopene from tomato paste using environmentally benign solvent was examined using several kinds of vegetable oil such as coconut oil, olive oil, soybean oil, palm oil, and sunflower oil as the solvent. Coconut oil resulted in the highest yield. A Box–Behnken design of response surface methodology was applied to optimize the process conditions (solvent/material ratio, extraction temperature, and extraction time). A second-order equation was developed to express the lycopene yield as a function of the process variables. Its validity was evaluated by comparing the experimental results and a significant agreement was achieved. The optimum conditions were a solvent/material ratio of 50:1, temperature of 45 °C, and extraction time of 45 min, which achieved a maximum lycopene yield about 80%.

用环保溶剂从番茄中提取番茄红素：Box-Behnken 设计和优化

摘要 以椰子油、橄榄油、大豆油、棕榈油和葵花籽油等多种植物油为溶剂，研究了使用环境友好型溶剂从番茄酱中提取番茄红素。椰子油的产量最高。应用响应面方法的 Box-Behnken 设计来优化工艺条件（溶剂/材料比、萃取温度和萃取时间）。开发了一个二阶方程来将番茄红素产率表示为过程变量的函数。通过比较实验结果来评估其有效性，并取得了显着的一致性。最佳条件为溶剂/材料比为 50:1，温度为 45 °C，提取时间为 45 min，可获得约 80% 的最大番茄红素收率。
