果皮富含番茄红素，是番茄酱生产厂废弃物的重要组成部分。采用5个自变量的中心复合设计，即溶剂/粗料比（20:1,30:1,40:1,50:1和60:1 v/w）；提取次数（1、2、3、4、5）；温度（20、30、40、50、60℃）粒度（0.05、0.15、0.25、0.35、0.43 mm）；以4、8、12、16、20 min为提取时间，考察其对番茄红素提取的影响。番茄红素的实验值为0.639 ~ 1.98 mg/100 g。建立的二级模型表明，番茄红素的决定系数（R-2）为0.99，标准误差为0.03。当溶剂比为30:1 v/w、提取次数为4、50℃、温度为0.15 mm、提取时间为8 min时，番茄红素的提取率最高，为1.98 mg/100 g。(C) 2007 Elsevier Ltd.版权所有。
Skin, rich in lycopene, is an important component of waste originating from tomato paste manufacturing plants. A central composite design with five independent variables, namely solvent/meal ratio (20:1, 30:1, 40:1, 50:1, and 60:1 v/w); number of extractions (1, 2, 3, 4 and 5); temperature (20, 30, 40, 50 and 60 degrees C) particle size (0.05, 0.15, 0.25, 0.35 and 0.43 mm); extraction time (4, 8, 12, 16 and 20 min) was used to study their effects on lycopene extraction. The experimental values of lycopene ranged between 0.639 and 1.98 mg/100 g. The second order model obtained for extracted lycopene revealed a coefficient of determination (R-2) of 0.99 and a standard error of 0.03. Maximum lycopene (1.98 mg/100 g) was extracted when the solvent/meal ratio, number of extractions, temperature, particle size and extraction time were 30:1 v/w, 4, 50 degrees C, 0.15 mm and 8 min, respectively.
