Use of Doehlert design in the optimization of extraction conditions in the determination of organochlorine pesticides in bovine milk samples by HS-SPME

Abstract

The extraction of pesticides lindane, heptachlor, aldrin, dieldrin and endrin from milk by HS-SPME was investigated followed by separation/detection of these compounds by GC-ECD.

Soybean (Glycine max L.) isoflavones: Chemical composition and its chemometrics-assisted extraction and authentication

“…A modern approach to the optimization process was commonly conducted by employing a computational experimental design (Kleijnen, 2010). In natural product chemistry, experimental designs can be applied in analytical method development , biological product enhancement (Farombi et al, 2018;Managamuri et al, 2017;Momen et al, 2016;Srivastava et al, 2018;Talluri et al, 2019), and parameters selection for efficiency and economic consideration in biochemical processing (Ciechomska et al, 2016;Ha et al, 2018;Merib et al, 2014;Xiong et al, 2016).…”

Recent Applications and Newly Developed Strategies of Solid-Phase Microextraction in Contaminant Analysis: Through the Environment to Humans

“…Various contaminants were determined by SPME technique in other food commodities (Table 2), such as milk [29,[177][178][179][180][181][182], fish [183][184][185][186][187], honey [188][189][190], tea [191][192][193], coffee [194,195], oil [196,197], butter [198], rice [199], chili [166,200,201], and seaweeds [202]. In particular, in milk SPME has been exploited in different coatings.…”

“…In particular, in milk SPME has been exploited in different coatings. The MOF-based coating was prepared for the analysis of bisphenol A [177], commercial fibers were used to assay organochlorine pesticides [178] and PAHs [179], whereas graphene-based fiber was fabricated for the determination of PCBs [180]. A very interesting approach for the analysis of contaminants in complex matrices was developed by Deng et al [29].…”

Influence of oxygen and long term storage on the profile of volatile compounds released from polymeric multilayer food contact materials sterilized by gamma irradiation

“…Its main advantages are simplicity, reproducibility and economy in time, reagents and further desorption in the injection port of a GCsystem. Some examples of recent applications include the determination of pesticides in milk, fruits or vegetables [12,13], organotin compounds in water or human urine [14,15], aldehydes in edible oils [16], volatiles in beer [17] or the assessment of aroma quality in red pepper paste [18], among others.…”
