基于二次模型和特殊立方模型的比较，以正己烷/丙酮/乙醇三种混合组分作为番茄红素提取液，采用简单的混合工艺设计，验证了番茄红素萃取率是提取过程中所用溶剂的函数这一假设。使用常规标准(P小于或等于0.15)来确定每个模型中的影响效果。虽然番茄红素提取中使用的主要成分是正己烷，但正己烷与乙醇(所有样品类型)和丙酮(番茄酱样品)之间存在正的二次协同作用；这表明包含所有三种成分的混合物对于优化提取过程是必不可少的。部分特殊立方模型产生了三个固定点，表明了优化生番茄、番茄酱和番茄酱中番茄红素提取所需的己烷、丙酮和乙醇的浓度。
A simple mixture process design based on the comparison of both quadratic and special cubic models and involving three mixture components (hexane/acetone/ethanol) as a solution for extracting lycopene from raw tomato, tomato sauce, and tomato paste was used to confirm the hypothesis that lycopene extraction rates are a function of the solvent used during the extraction process. Conventional criteria (pless than or equal to0.15) were used to identify influencing effects in each model. Although the major component used in lycopene extraction was hexane, there was a positive secondary synergistic interaction of hexane with ethanol (all sample types) and with acetone (tomato paste samples); this suggests that a mixture including all three components is essential for optimizing the extraction process. The partial special cubic model yielded three stationary points, indicating the concentrations of hexane, acetone, and ethanol required to optimize lycopene extraction in raw tomato, tomato sauce, and paste.
