Determination of fat in dairy products using pressurized solvent extraction.
Gravimetric fat data were obtained for a wide range of dairy products with fat contents ranging from 0.5 to 83% using pressurized solvent extraction at elevated temperatures and pressure (80-120 degrees C; 10.3 MPa). Extraction performance was sensitive to solvent composition, temperature, and sample matrix. By optimizing solvent mixtures, sample-solvent contact times of 8-10 min were sufficien...
متن کاملDesign, Construction and Evaluation of a Simple Pressurized Solvent Extraction System
Este trabalho descreve a construção e teste de um sistema simples de extração pressurizada com solvente (PSE). Uma mistura de acetona:água (80:20), a 80 oC e 103,5 bar, foi utilizada para extrair dois herbicidas (Diuron e Bromacil) de uma amostra de solo contaminado. Os herbicidas foram identificados e quantificados por cromatografia líquida de alta eficiência acoplada a detector por arranjo de...
متن کاملPressurized Solvent Extraction Medicinal Plants and Natural Products Pressurized Solvent Extraction (PSE) of medicinal plants and herbs for the determination of valuable compounds
Pressurized Solvent Extraction (PSE) is a modern extraction method that has been developed as an alternative to traditional methods such as Soxhlet or maceration; it offers advantages with respect to extraction time and solvent consumption. BUCHI’s SpeedExtractor enables the simultaneous extraction of six samples with maximum reproducibility and low solvent usage. Polyphenols and active compoun...
متن کاملComparison of solvent mixtures for pressurized solvent extraction of soil fatty acid biomarkers.
The extraction and transesterification of soil lipids into fatty acid methyl esters (FAMEs) is a useful technique for studying soil microbial communities. The objective of this study was to find the best solvent mixture to extract soil lipids with a pressurized solvent extractor system. Four solvent mixtures were selected for testing: chloroform:methanol:phosphate buffer (1:2:0.8, v/v/v), chlor...
متن کاملPressurized hot water extraction (PHWE).
Pressurized hot water extraction (PHWE) has become a popular green extraction method for different classes of compounds present in numerous kinds of matrices such as environmental, food and botanical samples. PHWE is also used in sample preparation to extract organic contaminants from foodstuff for food safety analysis and soils/sediments for environmental monitoring purposes. The main paramete...
