This work was aimed at evaluating the effect of the addition of monoacylglycerols (MAG) with different fatty acid composition, thus obtained from different vegetable oils such as olive (OO), soybean (SO), and palm (PO). MAG were added in the purified olive oil at different concentrations (5, 15, and 30 mg/g) and consequently the oxidative process was monitored. For this purpose, the purified oil added with MAG was subjected to oven test for 28 days, during which the multiparametric analysis of oxidation was carried out: peroxide value, spectrophotometric constants (K , K ), oxidized triacylglycerol, and triacylglycerol 270 232 oligopolymers. Our results showed that both OO and SO MAG significantly slowed the oxidative processes after 15 days, in a dose-dependent manner. For PO MAG, on the other hand, although the dose dependent effect was less evident, an antioxidant effect was observed that was greater than that observed for the other MAG, already detectable in the early stages of oven test.

Abstract
This work was aimed at evaluating the effect of the addition of monoacylglycerols (MAG) with different fatty acid composition, thus obtained from different vegetable oils such as olive (OO), soybean (SO), and palm (PO). MAG were added in the purified olive oil at different concentrations (5, 15, and 30 mg/g) and consequently the oxidative process was monitored. For this purpose, the purified oil added with MAG was subjected to oven test for 28 days, during which the multiparametric analysis of oxidation was carried out: peroxide value, spectrophotometric constants (K , K ), oxidized triacylglycerol, and triacylglycerol 270 232 oligopolymers. Our results showed that both OO and SO MAG significantly slowed the oxidative processes after 15 days, in a dose-dependent manner. For PO MAG, on the other hand, although the dose dependent effect was less evident, an antioxidant effect was observed that was greater than that observed for the other MAG, already detectable in the early stages of oven test.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
