Optimization of Processing Parameters for Extraction of Amylase Enzyme from Dragon (Hylocereus polyrhizus) Peel Using Response Surface Methodology

Figure 1

Three-dimensional curves for showing the significant interaction effect of independent extraction variables (e.g., temperature, time of mixing, pH of buffer, and buffer to sample ratio) on activity (a-b) and specific activity (c-d) of amylase were plotted.

(a) Amylase activity versus time and temperature

(b) Amylase activity versus pH of buffer and buffer to sample

(c) Specific activity versus buffer to sample and pH of buffer

(d) Specific activity versus pH of buffer and time
