Fatty acid profile and antioxidant properties of oils extracted from dabai pulp using supercritical carbon dioxide extraction

The present work was aimed to optimise the supercritical carbon dioxide extraction of dabai oil from dabai pulp and defatted pulp using RSM in comparison with hexane extraction method. Fatty acid profile and antioxidant properties of the extracted dabai oil were also determined. Optimal RSM conditio...
