The oil extracting process, there are many ways such as using solvent, compression, etc., and how interesting alternately. Using techniques of extraction with supercritical fluid crisis, which has many advantages, is no need to use chemicals in the extraction. To extract with high purity is free of chemical contamination. Which are environmentally safe and consumers more extraction with organic solvents. That may not be able to separate the solvent out completely. Therefore, the solvent residue. However, this technique has limitations. The substance into a state of crisis (Supercritical fluid supercritical fluid) can"t do. Need to rely on the tool that can control the temperature and high pressure, which is relatively high, generally in the millions of baht The production cost is relatively high. The price of the product has high prices accordingly.
