• Why should you choose a subcritical extraction machine?
  • Saves more than 70% of heat energy; With subcritical extraction machine, the residual meals have higher nutritional and biological activity ingredient. It is actually a low temperature extracting process (normal temperature extraction and low temperature desolventizing). All heat sensitive components are fully protected and remain original.
  • Which solvent is used in supercritical extraction process?
  • However recently there have been reports on use of various solvents such as propane, butane, hexane, ethanol, methanol and water for extraction at supercritical conditions. The use of co-solvents and modifiers enhances the performance of supercritical extraction process.
  • What is a subcritical extraction method?
  • Extraction at subcritical conditions has become an increasingly popular alternative method in the extraction of bioactive compounds from natural products, food waste, herbal plants, and in environmental applications. Plant materials contain highly valuable compounds such as essential oils, pigments, vitamins, antioxidants, and aroma.
  • What is supercritical fluid extraction?
  • Extraction of any compound requires itself to be environmentally friendly and efficient. Supercritical fluid extraction is one such process which is not only process efficient but also better than other conventional extraction processes. In most of the SFE, CO 2 is used over other solvents.
  • Which solvent is used for extraction?
  • The solvent used for the extraction was SC-CO 2 and it was found out that the amount of extraction compounds increased by increasing temperature and pressure. Further, Chrastil, and Mendez-Santiago and Teja models were used to correlate the acquired experimental data and evaluate the interactions between solute and solvent.
  • What is supercritical fluid extraction (SFE) & supercritical chromatography (SFC)?
  • 1. Introduction Supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC) have emerged as popular technologies for speedy, contamination free extraction and purification in the food and pharmaceutical industries.
