Sunflower Lecithin: Application of a Fractionation Process with Absolute Ethanol

Native or modified lecithins are widely used as a multifunctional ingredient in the food industry. A fractionation process of sunflower lecithin (a non GMO product) with absolute ethanol was used for obtaining enriched fractions in certain phospholipids under different experimental conditions (tempe...

description Native or modified lecithins are widely used as a multifunctional ingredient in the food industry. A fractionation process of sunflower lecithin (a non GMO product) with absolute ethanol was used for obtaining enriched fractions in certain phospholipids under different experimental conditions (temperature 35–65 °C, time of fractionation 30–90 min, ethanol/lecithin ratio 2:1, 3:1). Phospholipid enrichment in PC and PI fractions was obtained and analyzed by ³¹P NMR determinations. The percent extraction coefficients for different phospholipids (%E<sub>PC</sub>, %E<sub>PE</sub> and %E<sub>PI</sub>) in both fractions were calculated. Values of %E<sub>PC</sub> in PC fractions significantly increased (p < 0.05) from 12.8 (35 °C, 30 min, 2:1) to 57.7 (65 °C, 90 min, 3:1) at increasing temperature and incubation time. %E<sub>PE</sub> varied from 3.0 to 18.3 in the same fraction while %E<sub>PI</sub> presented lower values (<3%) under all the conditions assayed. The study of the effect of the operating conditions on the fractionation process evidenced a relevant influence of temperature, incubation time and to a minor extent of the ethanol/lecithin ratio on the enriched fraction yield% and selectivity of the main phospholipids (PC, PI, PE) estimated by %E<sub>PL</sub>. Response surface methodology (RSM) was utilized to explain the influence of the different parameters to optimize this process.
