Background & Aim: Sesame is one of the oldest cultivated plants in the world and is one of the oldest oily products used by humans. Sesame oil is an important industrial, oral and medicinal oil. Today, the use of ultrasound has grown significantly due to its effects on food storage and processing. Experimental: In this research, the response level model w...

Solvent extraction system is one of the effective techniques used for separation of metal cations from aqueous solutions [1-8]. It is a suitable method for preventing and protecting environment from pollution. The extraction of copper(II) using carboxylic acids has been a subject of much work research [9-13]. Lauric acid was employed as an extractant for the separation of numerous cations, the ...

This review attempts to provide an updated overview (including works published till June 2006) on the latest applications of compressed fluids as sample preparation techniques for food analysis. After a general review of the principles of supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE; also called accelerated solvent extraction, ASE or subcritical water extraction, ...

supercritical fluid extraction (scfe) is a soil remediation technology. at present, only a few companies are using from this method, all of which are technical based on conventional methods of extraction such as soilex solvent extraction. because of the hard enforcement of environmental conservation law, using green technology seems imperative. this paper endeavors to carry out the feasibility ...

The present paper reviews various pathways that will lead to reduction of organic solvent usage in pesticide residue analysis. Considerable reduction of solvent consumption can be achieved by miniaturizing the scale of sample extraction and cleanup and by simplifying the analytical procedures. Adoption of new analytical techniques, such as solid-phase microextraction and supercritical fluid ext...

An efficient and environmental-friendly extraction method has been developed for extraction of ursolic acid (UA) from Hedyotis diffusa by using subcritical water extraction (SWE). The experiments were carried out at different particle sizes (20–100 mesh), extraction temperature (120–200 ◦C), extraction time (10–50 min), solvent/solid ratio (20–40 mL/g), and extraction pressure (0.6–3.0 MPa).
