Chemical Characteristics and Thermal Oxidative Stability of Novel Cold-Pressed Oil Blends: GC, LF NMR, and DSC Studies

Abstract: Plant oils contain a high content of unsaturated fatty acids. Studies of food products have revealed a considerable disproportion in the ratio of ω6 to ω3. This article presents information on the healthful qualities of eight new oil blends that contain a beneficial proportion of ω6 to ω3 fatty acids (5:1), as well as their degradation during heating at 170 and 200 °C. The fatty acid profile was analyzed by gas chromatography (GC), content of polar compounds and polymers of triacylglycerols by liquid chromatog… Show more

“…Certain plant compounds, such as omega-3 fatty acids from seeds and nuts and flavonoids from fruits and vegetables, can improve cardiovascular health. These compounds help lower cholesterol levels, reduce blood pressure and prevent the formation of blood clots, reducing the risk of heart disease and stroke [40][41][42]. Phytochemicals, such as flavonoids and terpenoids, have been linked to improved cognitive function and brain health.…”

“…Differential scanning calorimetry (DSC) is an advanced analytical instrument which has broad applications dedicated to explaining the thermal behavior of lipid compounds, and is thus able to provide significant data regarding the authenticity and stability profiles of fats and oils [16]. Several research studies have proven the effective use of the DSC technique to explore the oxidative deterioration resulting from normal or accelerated shelf-life tests [17][18][19]. Compared to conventional chemical analyses, an assessment by DSC offers a significant database, expressed as the exothermic/endothermic phase transition phenomena manifested by curve changes as a function of temperature, which is related to the lipids composition of the oil.…”
