  • Which process is best for grape seed oil production?
  • Screw pressing is the most efficient process for producing grape seed oil with a high yield, but supercritical CO 2 process permits an increase of polyphenol co-extraction with oil. The GAME process allows extraction of more polyphenols than screw pressing and constitutes an interesting process considering oil yield.
  • How is oil extracted from grape seeds?
  • For SFE, oil extraction is performed by a continuous flux of CO 2 through the seed bed. The amount of oil extracted then is dependent on the solubility of CO 2 towards oil. Interestingly, uniaxial expression without CO 2 of grape seeds does not allow oil extraction.
  • What is ultrasound aided oil extraction?
  • Ultrasound assisted oil extraction extracts oil from vegetables, oilseeds, and nuts by using a suitable carrier. The key parameters influencing ultrasound aided extraction of oilseed include particle shape and size, moisture content of seed, amount of solvent, and extraction time/temperature.
  • Can ultrasonic assisted extraction extract seed oils for multifaceted food applications?
  • The application of ultrasonic assisted extraction to extract seed oils for multifaceted food applications is discussed in this study. Seed oils, which are notable sources of health-promoting characteristics and reservoirs of fatty acids and phytochemicals, are being targeted for effective extraction.
  • What is oil extraction yield?
  • Oil extraction yield was defined as the ratio of the mass of clarified oil recovered from extraction to the mass of oil originally present in the seeds for screw pressing experiments, and as the ratio of the mass of the oil phase recovered from SFE or GAME experiments to the mass of oil originally present in the seeds. 2.2.3.
  • Why do grape seeds have a low extraction yield?
  • GAME performed at 5.6 MPa leads to the lowest extraction yield (0.01 g/g). At a pressure of 5.6 MPa and a temperature of 104 °C, CO 2 is in a gaseous state. Therefore, the oil contained in grape seeds cannot be solubilised in CO 2, explaining the low yields.
