Popis: International audience; Camelina oil (Coil) contains 50-60 % of polyunsaturated fatty acids which are susceptible to oxidation. In this work, addition of phospholipids (0-20 mg/g) was assessed to improve the solubility of quercetin in Coil and enhance its oxidative stability. Results showed that the solubility of quercetin in Coil increased up to 7.7-fold by phospholipid addition. The solubility of quercetin in Coil was correlated to the phospholipid concentration and reached a maximum value of 1 298 g/g. The addition of phospholipid-quercetin formulations increased the Coil stability, measured at 60 °C, from 24 h up to 115 h. Coil saturated with only quercetin (168 g/g) did not significantly increase Coil stability, whereas phospholipids alone extended the oxidation lag time up to 40 h. This work successfully developed a solvent-free method for improving the solubility of quercetin in Coil and enhance its oxidative stability.
