FromTable 3, capsaicinoids of 98.3% had been removed from
FRPs by a twice-extraction. And red pigments could be obtained
by another twice-extraction or thrice-extraction from the residues after removal of capsaicinoids with a yield of 89.8% or
98.3%, respectively. Considering comprehensively other issues
such as energy consumption, the experimental time, and so on, a
twice-extraction was selected for extraction of red pigments in
this work.
