The production concerns various plants including extracts from, myrrh, serenoa repens, camelina, chia, rosemary, tomato, turmeric. It will also concern the specific extraction of <strong>terpenes <\/strong>and <strong>flavonoids<\/strong> also given the important studies that have recently led to new treatments for tumors practiced also using these compounds. An important role also has products obtained through the circular economy only in cases where the agricultural supply chain ensures effective organic quality raw materials.

Some of these have been optimized to remove the waxy component from the extracts. <strong>Waxes<\/strong> are complex and ubiquitous lipophilic molecules in the plant kingdom. They are a thorny issue in the extractive field, since they are distinctly apolar, with medium-high molecular weight and are extracted together with oil and other compounds, especially if a apolar substance such as supercritical CO2 is used as a solvent. In some cases the presence of these molecules in the extract is an added value, but in others it can only be a useless component that can complex and requisition other extracted substances from the oily solution. By removing the waxes, they can be affected by other post processes, useful for solubilizing the chemical compounds required in these lipid matrices. Some of these processes applied by Exenia are:<\/p>\n<ul>\n<li><u><u><img loading=\"lazy\" class=\"alignright size-medium wp-image-6580\" src=\"http:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B-300x200.jpg\" alt=\"\" width=\"300\" height=\"200\" srcset=\"https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B-300x200.jpg 300w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B-1024x681.jpg 1024w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B-768x511.jpg 768w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B-1536x1022.jpg 1536w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B-900x600.jpg 900w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B-600x399.jpg 600w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/03\/ART1963-B.jpg 1600w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/u><\/u><u>Centrifugation<\/u>: by using the centrifugal force it is possible to reduce the sedimentation time of the substances dissolved in a mixture, having different densities. In this way, after setting some variables such as the number of revolutions per minute and the centrifugation time, the mixtures rich in waxes will be divided into <strong>precipitate<\/strong> (consisting of the densest solutes, and therefore heavier in terms of molecular weight, such as waxes) and <strong>supernatant<\/strong> (consisting of the least dense component). By taking only the supernatant, there is a removal of the precipitate, or of the waxes, which can be treated later.<\/li>\n<li><u>Winterization<\/u>: the principle is always that of sedimentation, and of the separation of the mixture into supernatant and precipitate, but low temperatures are used to decrease the execution times. In fact, by modulating the temperature, the solvent properties of the mixtures are modified and the denser solutes will precipitate with greater speed, so as to allow separation by filtration.<\/li>\n<li><u>Purification with activated carbon<\/u>: in this case the separation takes place by size. During the preparation of this method, active carbons in powder form are arranged inside a column, which will constitute the stationary phase and form a filter, with pores of different sizes, based on the particle size. The mixture to be purified is <strong>percolated<\/strong> through this filter, which will retain the molecules with larger dimensions than the pores. Subsequently, the substances retained by the stationary phase can be recovered using specific eluent solutions.<\/li>\n<li><u>Fractionation<\/u>: of concentrated extracts of active ingredients (e.g. palm oil ration concentrate in tocopherol or vitamin E).<\/li>\n<li><u>Pasteurization<\/u> at room temperature (30\u00b0 C) for natural drinks and preservation of thermolabile vitamins and the aromatic characteristics of the alcoholic beverage<\/li>\n<li><u><u><img loading=\"lazy\" class=\"alignright size-medium wp-image-6525\" src=\"http:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/02\/Micronizzazione3-169x300.jpg\" alt=\"\" width=\"169\" height=\"300\" srcset=\"https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/02\/Micronizzazione3-169x300.jpg 169w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/02\/Micronizzazione3-576x1024.jpg 576w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/02\/Micronizzazione3-600x1067.jpg 600w, https:\/\/exeniagroup.it\/en\/wp-content\/uploads\/2020\/02\/Micronizzazione3.jpg 720w\" sizes=\"(max-width: 169px) 100vw, 169px\" \/><\/u><\/u><u>Micronization and microencapsulation<\/u> through the application of the Joule Thomson effect combined with the mechanical transfer of the extract through a fine conduit (nozzle) capable of sizing the drug powders. This micronization technology is an innovative technology that does not use toxic solvents, capable of producing microparticles by exploiting sub-critical conditions of the CO2 used as an agent: in rapid expansion the gas subtracts heat from the extract, crystallizing the compound.
