摘要: 微波强化浸取所得天然色素的产率不仅与微波的辐射功率、辐射时间有关,还与溶剂量、柚皮的破碎度等因素有关。为了把所有因素都考虑进去,首先采用“黑箱方法”先建立一个与数据拟合较好的数学模型,然后再逐渐逼近实验数据,最后用现代计算机技术按最小二乘法原则处理,确定式中的待定系数值。

Abstract: It is necessary to establish a mathematical model for microwave enhanced extraction because the yield of natural pigment is affected by average microwave output power, microwave irradiation time, solvent amount, crushed degree of pomelo peel, and so on. In order to take all factors into account, a mathematical model which keeps in touch with experimental data has been established by “Dark-Box” method. Then the experimental data is further regressed by computer and the coefficients of nonlinear equation are obtained.
