In this study, the peels of banana (composition shown in
Table 1) (10g) were used as a raw material and distilled
water and/or acetone were used as solvents. Effects of
the extraction time, solvent type, and temperature and
particle size on the extraction process of FOS
components from banana peels were investigated. In
batch extraction experiments, the ratio of ¼ was applied
in batch experiments for banana peel weight (g)/amount
of solvent (ml). Batch experimental system containing
the solvent and a raw material covered with paraffin
was subjected to defined temperature in shaking water
bath (HETO SBD 50; 150 rpm) during specified period.
After filtrating of the extract analyzing procedure was
performed and yield of the extraction was calculated
from Equation 1. All of the experiments were repeated
three times. Student's t test statistical analysis was
performed on the results obtained. Experimental
procedure was also summarized in Figure 1.
