Capsaicinoid extraction from peppers is typically performed using organic solvents, however, the extraction efficiencies
can vary with peppers, their parts and pre-extraction processing. In the absence of in depth information on
capsaicinoid extraction from haban˜ ero peppers, this work was undertaken to examine the processing parameters
for solvent extraction of capsaicinoids fromwhole haban˜ ero peppers (Capsicum chinense) and their various parts. The
effects of solvent type (ethanol, acetone and acetonitrile), pepper part(s) (seeds, shells), tissue preparation (freeze
and oven drying), and time on capsaicinoid recovery (capsaicin and dihydrocapsaicin) were evaluated. Across all
solvents, capsaicin yields were on average 16, 5 and 8 mg/g dry pepper part for seeds, shells and whole peppers,
respectively. Dihydrocapsaicin yield ranged from 0.65 to 9.17 mg/g dry pepper depending on interaction between
parts and preparation. Overall, higher yields of capsacinoids were obtained from oven-dried peppers using acetone
as the solvent.
