SFE is a process in which the gas beyond its critical temperature and pressure is fed to the extraction vessel in order to extract the desired compound/mixture of compounds from the product matrix (Figure 1). Under supercritical state ferrous gluconate every other daythe fluid has both the properties of gas and liquid, as it has density like liquid and viscosferrous gluconate 300mg how much ironity like gas. This property enhances the diffusivity of the fluid in the product-containing matrix and increases the rate of extraction of the targeted compound/s. SFE is a selective process in which the process variables, such as pretreatment to plant material, temperature, pressure, particle size, moisture content, solvent flow rate, extraction time and co-solvents (usually 1 to 10 percent) are varied according to the target compound to be extracted.2
