Table 5.

The acid value of different oil samples during storage (mg KOH/g oil)

Sample	Day
Sample	0	15	30	45	60
CON	0.24^Ea	0.36^Da	0.53^Ca	1.08^Ba	1.63^Aa
TBHQ	0.20^Db	0.23^Db	0.39^Cb	0.70^Bb	1.17^Ab
SFE	0.18^Db	0.20^Db	0.25^Cc	0.34^Bc	0.432^Ac
SWE	0.19^Db	0.20^Db	0.27^Cd	0.39^Bd	0.50^Ad
MIX(SFE–SWE)	0.17^Db	0.17^Dc	0.22^Ce	0.30^Be	0.36^Ag

Note Pumpkin peel extract obtained by supercritical fluid extraction (SFE) and subcritical water extraction (SWE). MIX(SFE–SWE) is a mixture of SFE and SWE extracts, and CON is control oil (Without any antioxidant)
