Response Surface Methodology

526
Response Surface Methodology (RSM) is a collection of statistical and mathematical techniques used to develop, improve, and optimize processes. It is particularly valuable when many input variables or factors potentially influence a response variable.
The process of RSM involves several key steps:

  • Independent variables included ethanol concentration (0-70%), extraction time (30-90 min), and temperature (50-70°C).
  • High-performance liquid chromatography (HPLC) was used to analyze 6-gingerol and 6-shogaol content.

Main Results:

  • Regression models showed high accuracy with determination coefficients over 0.892.
  • Optimal conditions for extraction yield were 41.38% ethanol, 78.16 min, and 70°C.
  • Predicted optimal content for 6-gingerol was 39.55 mg/g and for 6-shogaol was 2.44 mg/g.

Conclusions:

  • The optimized extraction process effectively maximizes functional compounds from ginger.
  • RSM is a suitable method for optimizing ginger extraction parameters.
  • The study provides valuable data for industrial-scale extraction of ginger's bioactive compounds.
