  • How to extract peppermint oil?
  • Extraction of peppermint oil can be done by steam distillation , hydro distillation , solvent extraction , ultrasonic extraction, subcritical extraction and supercritical extraction . Mejri et al. reviewed various extraction processes of essential oil and found many drawbacks associated with traditional solvent extraction.
  • What is the solvent extraction process for peppermint plant?
  • The solvent extraction process does not necessarily require high temperatures, therefore potentially providing milder process conditions for obtaining essential oils from peppermint plant. In terms of process times, the extraction process can be influenced by many factors such as type of solvent, temperature, and sample-to-solvent ratio.
  • How much does peppermint oil extraction cost?
  • Total indirect cost (Cost of design and construction) of system estimated is US$2,688.18. Hence, total initial investment needed by a potential investor for establishing a pilot plant of peppermint oil extraction by steam distillation extracting 24 kiloliters of essential oil per year (300 working days) amounts to 7,680.53 US$ (Fig. 5).
  • How are mint extracts extracted?
  • The traditional way to produce mint extracts is via steam distillation or solvent extraction, both long and energy consuming processes. This paper investigated various extraction methods, namely room temperature extraction, reflux temperature extraction, ultrasonic assisted room temperature extraction and microwave-assisted extraction.
  • What are the energy matrices for peppermint oil extraction?
  • Energy matrices, energy, embodied energy, economics and environmental suitability of conventional distillation system for peppermint oil extraction are estimated. Life cycle EPFs and LCCE were estimated at 29.23, 33.13 and 38.98, and 12.59 %, 14.79 % and 17.86 % for 1500, 1700 and 1900 kg batch sizes.
  • Where is conventional steam distillation system used for peppermint oil extraction?
  • Conventional steam distillation system (CSD) for peppermint oil extraction is installed at Birpura village, Jhansi, India (25° 36 N¡ä18.40¡åE). Experiments were carried out for different batch sizes (1500 kg, 1700 kg and 1900 kg). Details of experimental setup are described in Table 1.
