The aim of this work was to use the HPSEC analysis of polar compounds to assess the level of oxidative and hydrolytic degradation of the lipid fraction of mortadella. The results indicated high primary oxidative degradation of the lipid fraction in the samples, with a mean value for oxidized triacylglycerols of 1.77%, and low secondary oxidation, with a mean value for triacylglycerol oligopolymers of 0.16%. In addition, in some cases, significant hydrolytic degradation was found. HPSEC analysis of polar compounds, to evaluate the level of oxidative and hydrolytic degradation of the mortadella lipid fraction, could be used as an alternative to commonly used techniques, some of which are not always reliable.

Abstract

The aim of this work was to use the HPSEC analysis of polar compounds to assess the level of oxidative and hydrolytic degradation of the lipid fraction of mortadella. The results indicated high primary oxidative degradation of the lipid fraction in the samples, with a mean value for oxidized triacylglycerols of 1.77%, and low secondary oxidation, with a mean value for triacylglycerol oligopolymers of 0.16%. In addition, in some cases, significant hydrolytic degradation was found. HPSEC analysis of polar compounds, to evaluate the level of oxidative and hydrolytic degradation of the mortadella lipid fraction, could be used as an alternative to commonly used techniques, some of which are not always reliable.
