In general the RSM studies based
on three (or more) parameters are useful to understand the
interaction of parameters on desired response. However, the
effects of two process parameters on response were also reported
for other systems [26,27]. Mathematical model for extraction of
oil were developed to describe the effects and relationship
between the process parameter. Collected oil samples were characterized for physico-chemical values, thermal properties and its fatty acid composition to measure its suitability for biodiesel
production.
