In comparison
with previous work, extraction with tomato seed without rinsing
had a higher efficiency than that of Topal et al. (2006), indicating
that even without the use of THF as a rinsing method, yield of
carotenoid can be improved by the addition of tomato seed oil in
the supercritical CO2 extraction. In addition, seed oil may also be
used to replace the toxic organic solvent used to remove carotenoids
remaining in the extraction system.
