Determination of Overall Mass Transfer Coefficient for 6-Gingerol and 6-Shagoal in Subcritical Water Extraction

Article Preview

Abstract:

Subcritical water extraction (SWE) is introduced in the extraction of ginger bioactive compounds, namely 6-gingerol and 6-shagoal. The extraction mechanism is identified using mass transfer coefficient model. The overall mass transfer coefficient, k or driving force for each compound is measured through experimental determination. Compound identification and analysis iss conducted using High Performance Liquid Chromatography (HPLC). The k value for 6-gingerol and 6-shagoal under optimized condition (130°C, 3.5MPa) of 28:3 (ml:g) solvent to sample ratio are 0.02849 cm/min and 0.04873 cm/min, respectively.
