Extraction of Fucoxanthin from Raw Macroalgae excluding Drying and Cell Wall Disruption by Liquefied Dimethyl Ether
Macroalgae are one of potential sources for carotenoids, such as fucoxanthin, which are consumed by humans and animals. This carotenoid has been applied in both the pharmaceutical and food industries. In this study, extraction of fucoxanthin from wet brown seaweed Undaria pinnatifida (water content was 93.2%) was carried out with a simple method using liquefied dimethyl ether (DME) as an extrac...
متن کاملEconomical Wet Extraction of Lipid from labyrinthula Aurantiochytrium limacinum by Using Liquefied Ddimethyl Ether
Recently, a simple method for the extraction of lipids from wet biomass using liquefied dimethyl ether (DME) without drying, cell disruption, or heating was proposed. Here, the versatility of this method was evaluated for labyrinthula Aurantiochytrium limacinum (A. limacinum). The liquefied DME was passed through the extractor that filled by A. limacinum at different time intervals. The extract...
متن کاملExtraction of acEtic acid from WatEr Using isopropyl EthEr
69 Unit operations are ubiquitous in any chemical process. One of their main purposes is to achieve separation in order to recycle unconverted reactants or reach product purity specifications. If two phases are brought into intimate contact, a few components migrate from one phase to the other in every stage of the unit. Then, the two phases are separated. When we consider equilibrium-staged se...
متن کاملOptimization of phenol and flavonoid extraction compound of Adiantum capillus-veneris L. using ultrasound assisted extraction
Background: Antioxidants are molecules which able to control free radicals and prevent the oxidants of other molecules considering undesirable effects of synthetic anti oxidant. In recent years using of natural anti oxidant gets the great importance. The secondary metabolisms of plants are rich sources of phenol and flavonoids considered as the most important natural antioxidant. Objective: In...
متن کاملDFT study of dimers of dimethyl sulfoxide in gas phase
Density functional (DFT) calculations at M05-2x/aug-cc-pVDZ level were used to analyze the interactions between dimethyl sulfoxide (DMSO) dimers. The structures obtained have been analyzed with the Atoms in Molecules (AIMs) and Natural Bond Orbital (NBO) methodologies. Four minima were located on the potential energy surface of the dimers. Three types of interactions are observed, CH•••O, CH•••...
