In this work, fresh red
peppers without any drying process were directly used as materials
for stage extraction of capsaicinoids and red pigments with ethanol
as solvent. Through combination offirst extraction of capsaicinoids
and then extraction of red pigments, the capsaicinoids would be
removed entirely from the FRPs with 40e50% ethanol aqueous in
which the losses of red pigments is about 0.8e1.7% and then the red
colorants were extracted from the residues without capsaicinoids
with 95% ethanol.
