Process Optimization for Acidic Water Extraction of Limonin from Citrus Peels by Response Surface Methodology
摘要
Abstract
The pH of pure water was adjusted with sulfuric acid to provide a solvent for the extraction of limonin from citrus peels. Limonin quantification was performed by HPLC. Based on one-factor-at-a-time experiments, a three-variable quadratic rotary unitization design combined with response surface methodology was used to optimize three conditions for acidic water extraction of limonin from citrus peels, and a mathematical model describing limonin yield versus the three extraction conditions was built. The optimal extraction conditions of limonin from citrus peels were 2.6 h extraction at 61.2 ℃, pH 4 and a solid-toliquid ratio 1：19.2 （g/mL）. Under the optimized conditions, a limonin yield of 0.117 mg/g was achieved.关键词
