Applications of supercritical carbon dioxide in research and manufacturing industries

Abstract

    A wide range of technologies is available for the extraction of active components. Traditional extraction technologies are difficult to achieve high extraction efficiency. In addition, the products of these extractions might be not suitable for using in food, medicine or direct applications to luxury cosmetic products due to decomposed substance, byproducts and residues of toxic. Therefore, many extraction technologies are developed. The choice of appropriate technique depends on the economic feasibility and suitability of the process to the particular situation. Among of these, supercritical technology, a modern technology, which has been widely used in the research and production, especially for the fluid carbon dioxide (CO2). This solvent shows many important advantages, such as without solvent residure, nontoxicity and green solution . In this article, we reviewed the recent studies and potential applications of supercritical fluid CO2 in research and industrial scale. This might be useful to improving the quality of products. . It is especially important in the competitive market during the global integration.
