Supercritical CO2 Extraction of Cannabinol from Hemp and Its Antibacterial Activity

Supercritical CO2 extraction of cannabinol from hemp was established, and the antimicrobial properties of the extracts were investigated. Through the analysis of single factor and orthogonal test, the optimum extraction process of three cannabinoids from hemp by supercritical CO2 was determined: extraction temperature 45 C, extraction time 70 min, entrainer dosage 300 m L, extraction times 3 times. The bacteriostasis tests of E. coli and Staphylococcus aureus with MIC of 8 mg/ml and 6 mg/ml were carried out by filter paper method. Under these conditions, cannabinol (CBD) was 3.189 mg/g, hexahydrocannabinol (CBN) was 2.206 mg/g, tetrahydrocannabinol (9-THC) was 58.757 mg/g, that is, the three cannabinoids were 64.152 mg/g. The diameter of bacteriostasis circle of Escherichia coli and Staphylococcus aureus were 15.4 mm and 25.8 mm, respectively. The supercritical extract had certain bacteriostasis.

Application of Large Supercritical Extraction Equipment in Natural Product Development

Image
Supercritical fluid extraction (SFE) is one of the most advanced separation and extraction technologies in the world. In recent decades, it has attracted great interest of researchers all over the world. Through the efforts of researchers, it has made considerable progress. In the fields of medicine, chemical industry, food, petroleum, environmental protection and cosmetics, a number of valuable topics have been completed, and a new industry has been formed worldwide. Developing and utilizing supercritical fluid extraction (SFE) technology to realize large-scale industrial production is a major breakthrough in transforming dozens or hundreds of scientific research achievements that have been developed in the laboratory into productivity and economic benefits. Supercritical fluids have special solubility, which was discovered by Americans at the end of the 19th century. It was not until the 1970s that Germany was applied to beer processing to extract beer and other industrial applicati

What's the SCFE Workshop Operation Rules

Image
Supercritical Fluid Extraction Mcahines SCFE Workshop Operation Rules a)The environment should be clean and items tidy. Safe passage is clear without any obstacles. b)Good ventilation in the workshop should be guaranteed to avoid workers’ lack of oxygen led by high CO2 density. c)Chloride ion content in the water used in this system should not be more than 25mg/L, PH value 6.5~8.5 and TDS value not more than 300. d)Overall power needed for this system is 650Kw/380V three-phase electricity. User should guarantee system power distribution demand for extraction workshop. e)CO2 fluid used for the equipment should meet the requirement of food grade CO2 standard. CO2 volume fraction is not less than 99.9%. f)If steam heating is adopted for the equipment, user should provide saturated steam 0.5~0.7MPa, 550~600kg/h.

Supercritical Fluid Extraction of Tea Aroma Components

Image
Taking Qianling Yinhao tea as a sample, the technological conditions of supercritical fluid extraction (SFE) of tea essential oil were studied by orthogonal design. The optimum extraction conditions were as follows: pressure 25 MPa, temperature 45 C, CO2 flow 8 L/h and time 4 h. Under these conditions, the maximum yield was 2.57%. The main and secondary factors affecting the extraction rate were time > pressure > temperature > flow rate. Through gas chromatography-mass spectrometric analysis (GC-MS) and sensory evaluation of the extracted essential oil, CO2 SFE can extract the main aromatic substances from tea. The extracted tea essential oil has the same aroma as the original tea, and has a high yield. It can be used for industrial preparation.
