Response Surface Methodology for Optimization of the Extraction Technology of Pigment from Black Rice

Abstract:

Response surface methodological studies of extraction technology of pigment from black rice was carried out by a two-level fractional factorial design involving four variables, namely extraction time (min), extraction temperature (°C), liquid-solid ratio (ml/g), extract concentration (%). The results indicated maximum extraction efficiency at 30 min, 70 °C, with 8 ml/g liquid and solid ratio and 75% extract concentration, which was also verified by experimental data. 84.58% pigment can be extracted from black rice when the extraction progression is one.
