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 (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 (%EPC, %EPE and %EPI) in both fractions were calculated. Values of %EPC 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. %EPE varied from 3.0 to 18.3 in the same fraction while %EPI 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 %EPL. Response surface methodology (RSM) was utilized to explain the influence of the different parameters to optimize this process.Fil: Cabezas, Dario Marcelino. Provincia de Buenos Aires. Gobernación.

3D-Integrated Multi-Sensor Demonstrator System for Environmental Monitoring
This paper summarizes the outcome of the EC FP7 project MSP - Multi Sensor Platform for Smart Building Management (Grant Agreement No. 611887). The MSP consortium comprising 17 partners from 6 European countries developed a full manufacturing chain for 3D system integration, which has never been realized before. It enables 3D-integration of highly sophisticated components and sensor devices on a CMOS electronic platform chip. The final multi-sensor system comprises a variety of gas sensors as well as optical sensors for ultraviolet, visible and infrared light. The MSP demonstrator system implemented in a wearable wristband device integrates a total of 57 sensors - this is a worldwide unique sensor system
