Legends to the Figures
Figure 1. Oleoresin extraction yield (%) from sorghum grain as
a function of extraction condition. The results are expressed as the
mean of 3 replicates and standard deviation (bars). The lower and upper
superscripts indicate the significant differences between the solvent
type for conventional solvent or ball mill-assisted extraction
processes, respectively. The Roman numerals show the differences between
the type of extraction for each solvent.
Figure 2. FTIR spectra of oleoresins obtained from sorghum
grain with different extraction conditions. The arrows indicate bond
stretching of interest.
Figure 3. Particle size (A) and zeta potential (B) of oleoresin
dispersions from sorghum grain as a function of extraction condition.
The results are expressed as the mean of 3 replicates and standard
deviation (bars). The lower and upper superscripts indicate the
significant differences between the solvent type for conventional
solvent or ball mill-assisted extraction processes, respectively. The
Roman numerals show the differences between the type of extraction for
each solvent.
