Abstract:

Based on single factor experiments, central composite design (CCD) combined with response surface methodology (RSM) was employed to optimize alcohol extraction of red pigment from sunflower hulls. Results showed that the optimal values of crucial process conditions such as extraction temperature and time and material/liquid ratio were 54 ℃, 112 min and 1: 22, respectively. Under these conditions, the maximum red pigment yield was predicted to be 661.74 mg/100 g, very close to the observed value.

Key words: sunflower hull red pigment (SHRP), response surface methodology (RSM), extraction yield
