Considering the results of single-factor experiment and the
results of orthogonal array design comprehensively, the optimal
conditions of extracting capsaicinoids from FRPs were summarized
as follows: The extractive temperature of water bath was at
90 C; the ratio of solvent to material was 4 (mL/g); the extractive
time was 120 min; and the concentration of ethanol was 40%e
50%.
