Blog about supercritical fluid
Among several supercritical fluid (abbreviated SCF) technologies, the earliest developed, most researched and industrialized product technology is undoubtedly the supercritical fluid extraction (abbreviated SFE) technology.
According to the results of single factor investigation, it is preliminarily determined that the separation process of piperine in the supercritical CO2 extract of pepper is: dripping absolute ethanol in a constant temperature water bath at 40℃, the dosage is 1:5 (w/v), and then 1℃/ The cooling rate of 5min is reduced to 0℃, and it is placed at 0℃ for 4h to crystallize.
A company in Guangdong, China released the results of a study on supercritical CO2 extraction of black pepper essential oil, probably in 2012.
Liquid phase mixture extraction and separation can basically be processed by continuous countercurrent supercritical extraction device.
The technical feature is the coupling of CO2 extraction and distillation and rectification, which can effectively play the separation role of the two and improve the purity of the product.
Celery seed oil exists in the cells of seeds, with less oil in the seed coat and more oil in the seed kernels. In order to increase the contact area between CO2 and seeds and reduce the diffusion distance between extractant and extractant in the biological matrix, it is necessary to grind it to the appropriate size according to the raw materials.

Antioxidants, rosemary essential oil, etc. can be extracted from rosemary.The main components of antioxidants are diterpenoids, flavonoids, triterpenoids and other compounds with antioxidant functions; rosemary essential oil is a liquid oil composed of more than 30 volatile components.
Supercritical CO2 extraction of ginger essential oil is light yellow, and the yield has increased from about 1% of traditional steam distillation to 4.38%.
Distillation extraction VS CO2 supercritical extraction of lavender essential oil antioxidant effect
The lavender essential oil extracted by the two methods had strong antioxidant capacity and was dose-dependent. In the five oxidation systems, the antioxidant effect of lavender essential oil extracted by supercritical CO2 extraction method is stronger than that of lavender essential oil extracted by steam distillation method.
