Effect of some Cultivation Factors and Extraction Methods on Terminalia Catappa L. Seed Oil

Table 3

Effect of extraction methods on FFA, AV, and PV of seed oil.

Extraction methods	FFA (%)	AV (mg KOH/g)	PV (meq O2/kg oil)
M1
M2
M3
M4
M5
P value	<0.0001	<0.0001	<0.0001

Note: different letters (a, b, c, …) showed the significant difference in the same column at 0.05 level. The oil extraction methods: cold screw pressing (M1), hot screw pressing (M2), hydraulic pressing (M3), solvent extracting (M4), and cold screw pressing combined with cake solvent extraction (M5). FFA: free fatty acid; AV: acid value; PV: peroxide value.
