| Description |
The study gives an insight into the effect of low frequency ultrasonic enhancement of solvent extraction on the
quality of non-edible oils (Jatropha and Pongarnia as model seed varieties) in comparison to conventional
methods or extraction i.e. direct reflux or soxhler extraction using hexane. A series of experiments have been
carried out to study the effect of variables; solute to solvent ratio (I :2.5-1: 10) and reaction time (30s-60 min) on
the yield of oil.The quality of oil extracted by different methods have been assessed by determining the acid value
of oil by ASTMD-974i04 method. a measurement of triglyceride and Fattyacid degradation. by the presence of
phorbol esters injatropha curcas and phenolic compounds in Pongamia oil analyzed using HPL.C.Underoptimized
conditious solute to solvent ratio or 1:10 (w.v), 3 rnin extraction time yields ยท95't pure' oil h,lVing' I~ FFAin
Jatropha curcas and 30 s extraction time in Pongamia seed yields oil with less than 21 FFAin comparison to
conventional method of extraction in 16 h.
