  Corn silk is an excellent source of many bioactive compounds, which is well known functional food and traditional herbal medicine. The aim of this study was to evaluate the effects of Novozym 33095 treatment to improve the phytochemical contents and bioactivities in unfertilized corn silk ethanol extracts. Furthermore, the treatment conditions were simultaneously optimized using a response surface methodology with a central composite design. The influence of Novozym 33095 concentration, reaction temperature, and reaction time on total polyphenol contents, total flavonoid contents, maysin contents, 2,2-diphenyl- 1-picrylhydrazyl radical scavenging activities, and tyrosinase inhibition was analyzed. The following optimal conditions were determined by simultaneous optimization of several responses with the Derringer’s desirability function using the numerical optimization function .. View More»
