3.4. Effects of rinsing method
In order to determine maximum efficiency of the extraction
process, organic solvent was used as a rinsing solvent to dissolve
remaining extracted carotenoids on the tubing wall. The rinsing
method was applied after the extraction using tetrahydro furan
(THF), which was pumped into the tubing line for 5 min at 1 mL/
min of flow rate.
Fig. 4 shows the effect of THF rinsing method with comparison
to previous work carried out by Topal et al. (2006). As shown in
Fig. 4, the THF rinsing method gave higher recovery both for the
lycopene and b-carotene. Use of the rinsing method is known to
