Hurood cheese (namely Hurood) is a traditional acid-coagulated in China. This work investigated key aroma compounds and their potential correlations with dominant species of sampled from three distinct geographical origins. Key were determined according to Gas chromatography–mass spectrometry (GC–MS), gas chromatography–olfactometry (GC–O), relative odor active values (ROAVs) analyses. In addit...

Gas chromatography is an analytical technique for separating and analyzing individual components in a gas mixture. Temperature programming is a form of gas chromatography in which the column temperature is controlled to follow a specific heating rate, dwell time and cooling rate during the course of the analysis. Temperature programming enables separation of a wider range of components, when co...

background food born pathogenic bacteria are the most important agents of infections in humans, and food spoilage also results in economic losses in food industry. objectives the aim of this study was the evaluation of chemical components, total phenolic content, antioxidant and antibacterial activities of artemisia dracunculus essential oil. materials and methods the essential oil of tarragon ...

Here we present a workflow for in-depth analysis of milk lipids that combines gas chromatography (GC) for fatty acid (FA) profiling and a shotgun lipidomics routine termed MS/MSALL for structural characterization of molecular lipid species. To evaluate the performance of the workflow we performed a comparative lipid analysis of human milk, cow milk, and Lacprodan® PL-20, a phospholipid-enriched...

Haloacetic acids (HAAs) are a group of disinfection by-products formed in chlorinated water. Due to their potential health effects and widespread occurrences, HAAs are regulated in drinking water in the United States under a promulgated regulation. To better control the formation of HAAs in drinking water, a reliable and accurate analytical method is needed for HAA monitoring. In the present st...

In this research, CaO (calcium oxide) nanoparticles were synthesized by Co-Precipitation method in the absence and presence of Polyvinylpyrrolidone (PVP) via using calcium (II) nitrate. The Polyvinylpyrrolidone (PVP) was used as a capping agent to control the agglomeration of the nanoparticles. The synthesized samples were characterized via SEM, XRD and FTIR techniques. The average sizes of nan...

Physical and chemical properties that may be used to determine the purity of several Fusarium mycotoxins have been investigated. A combination of analytical procedures, which include high performance thin-layer chromatography (HPTLC), liquid chromatography (LC), gas chromatography (GC), gas chromatography/mass spectrometry (GC/MS), ultraviolet spectrometry (UV), and nuclear magnetic resonance (...

Litsea cubeba L., also named as Makauy, is a traditional herb and has been used as cooking condiment or tea brewing to treat diseases for aborigines. The present study was undertaken to explore the chemical compositions of the fruit essential oil of L. cubeba (LCEO) and the immunomodulatory effect of LCEO on dendritic cells and mice. The LCEO was analyzed using gas chromatography (GC) and gas c...

Abstract Levamisole is an anthelminthic that was first used as a de-worming agent in humans and animals. It has also been used to treat inflammatory conditions as well as certain types of cancer. Levamisole was discontinued for human use in the early 21st century due to toxic side effects including agranulocytosis and vasculitis. Recently, levamisole was discovered as a cocaine adulterant after...
