The six key factors affecting the extraction of CO2 are: pressure, temperature, CO2 flow rate, time, co-solvent and particle size of raw materials.
Extraction pressure
The extraction pressure determines the composition of the extract.
High pressure means that the extraction time is shortened, and more extracts will be obtained. However, we need to be cautious to increase the extraction pressure, because more ineffective extracts will be obtained under high pressure. In our thirty years of extraction experiment, we know that with proper extraction pressure process, pure extracts will be obtained at one time.
Extraction temperature
Take the extraction of terpenoids limonene and carvone as an example: when the extraction pressure is 8MPa, the temperature rises from 35°C to 60°C, and the solubility of the two compounds decreases due to the decrease in the density of the CO2 fluid. When the temperature exceeds 60°C, as the temperature increases, the corresponding solubility will increase.
Therefore, the extraction temperature setting often requires more extensive extraction experience. BIT engineers are good at this field, please contact us, we will give you better extraction suggestions.
The ginger oil and oleoresin obtained from supercritical fluid extraction of Zingiber officinale. Solvent free pesticide-tested and certified organic high-grade quality.
It has a special smell and spicy taste. It has the characteristic aroma of ginger.
Fennel oil is extracted from dry fennel seeds. This is an herb with a long medical reputation believed to convey longevity, courage and strength.
The optimization black pepper Essential oil is extracted from berries of black pepper by supercritical CO2 fluid and light greenish in appearance.
This oil is free from solvent, pesticide residues and heavy metal traces and therefore is ideal for high quality pharmaceutical, cosmetic, cosmoceutical, nutraceutical formulations and food products.
Cumin (Cuminum cyminum) is in the parsley family of essential oils. The oil is obtained through co2 extraction. Cumin is a small, delicate, annual herb more like a ground cover. It grows about 20 inches high and has slender stems, dark green feathery leaves and small pink or white flowers followed by small seeds.
Supercritical CO2 fluid extraction is a novel and effective separation technology that has become increasingly popular in the field of natural pigments and active ingredients. In this study, we aimed to investigate the optimal conditions for extracting chili red pigment and capsaicin using supercritical CO2 fluid extraction. First, the effects of extraction conditions, including pressure, temperature, time, and the addition… Read More »Supercritical CO2 fluid extraction of Chili red pigment and capsaicin
What is supercritical fluid extraction?
A Beginner’s Guide to CO2 Extraction Method. Free 100⁺ CO2 Extraction Process. Supercritical Fluid Extraction for Essential Oil, Herb, Perfumery, Pigment.
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.
What is oleuropein? Oleuropein the early 20th century, a polyphenol compound was isolated from olive leaves. It has the structure of a schicyclic alkene station and is called oleuropein. Research at home and abroad shows that oleuropein has antioxidant, anti-tumor, and antibacterial properties, Lower blood sugar, and other effects. Because of its obvious pharmacological properties, oleuropein is considered to be… Read More »Supercritical CO2 Extraction Of Oleuropein From Olea Europaea Leaves
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.
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.
