Supercritical CO2 Extraction of Peppermint Oil — Supercritical CO2 Extraction of Peppermint Essential Oil

peppermint co2 oil & extraction porcess

peppermint co2 oil

The dry aerial part of peppermint, a plant of the Lamiaceae family, whose volatile oil has a strong refreshing fragrance and is a good medicine. It has the functions of dredging wind, heat dissipation, expectorant, detoxification, bacteriostasis, and anti-oxidation. It is used to treat wind-heat, colds and headaches. , Red eyes, sore throat, toothache, etc. For peppermint volatile oil, the traditional extraction method is mostly steam distillation. Due to the high temperature of the method, it is easy to decompose some heat-sensitive components, and the oil yield is low.

Features of peppermint CO2 oil

This excellent CO2 extraction of peppermint leaves is a useful alternative to standard peppermint essential oil. Its fragrance is warmer and calmer than the EO and also a little more aromatic, tending toward spearmint.

Indeed, there is less menthol and camphor in the CO2 and more diverse components in the GC readout, pointing to more complexity and depth of character.

Compare the scent of the essential oil, this peppermint CO2 Oil and a fresh mint leaf and you’ll find that the peppermint CO2 extraction oil is vastly more realistic and true to the leaf. So if you’re after a more naturalistic peppermint for your experiments, go for this CO2.

Peppermint oil extraction process

100L Supercritical CO2 Extraction Machine — Peppermint Oil Supercritical CO2 Extraction Machine

The best process for peppermint oil CO2 extraction

supercritical CO2 extraction peppermint oil machine is 1L, mint is crushed to 20 mesh, extraction pressure is 15MPa, extraction temperature is 50℃, CO2 flow rate is 40L/H, separation pressure is 6MPa, and separation temperature 50℃, extraction time is 90min. The extraction rate under this process condition is 3.2%;

Steam distillation

Weigh 200g of mint that has been dried and crushed through a 20 mesh sieve, add 1200mL of water, soak for 60min, distill for 3h, collect the volatile oil, dehydrate it with anhydrous sodium sulfate, and weigh it. The calculated yield is 0.84%. The volatile oil is brown. Liquid with special fragrance.

CO2 extraction VS steam distillation method of peppermint oil

The ABTS and FRAP methods were used to detect the antioxidant capacity of peppermint supercritical extract, and compared with the antioxidant capacity of peppermint volatile oil extracted by steam distillation. The results showed that the antioxidant capacity of peppermint volatile oil extracted by supercritical CO2 extraction method was stronger than that of steam distillation method extracted peppermint volatile oil.

Supercritical Fluid Systems

What is SCFE

Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids as the extracting solvent.
