Abstract
In this study, the effect of extraction processes on the physicochemical
characteristics and antioxidant potential of baobab (Adansonia digitata L.) seed
oil was evaluated. The oils were extracted, on the one hand, by cold pressing,
and on the other hand, with three types of organic solvents (acetone,
chloroform, n-hexane). The recorded results indicated that the extraction yield
of baobab oil was significantly impacted by both the extraction method and the
polarity of the solvent used. In addition, chloroform provides the best
extraction yield (40.12 ± 0.607). However, extraction by cold pressure preserves
at best the physicochemical and bioactive properties of the extracted oils.
Indeed, the pressing oil contains a content of phenolic compounds (0.047 ±
0.0024 mgEAG/g of oil) and a very high radical scavenging activity (DPPH)
(31.71% ± 0.61%). For the various oils extracted, the minimum and maximum
values were 0.50 and 3.17 mEq·kg

−1
; 1.457 and
1.465; 205.37 and 233.587 mgKOH/g respectively for the peroxide, iodine,
refractive and saponification values. The color parameters (L*, a* and b*) of the
oils also differ depending on the nature of the organic solvent used. Principal
component analysis (PCA) and correlation analysis were performed on the
physicochemical properties and the antioxidant potential of the extracted oils.
Therefore, the results suggest the mixed use of acetone and hexane to obtain oil
comparable to that extracted by cold pressing.
