Discovery of Spoilage Markers for Chicken Eggs Using Liquid Chromatography-High Resolution Mass Spectrometry-Based Untargeted and Targeted Foodomics.

The current approaches remain insufficient for measuring chicken egg spoilage or present analytical limitations. This study aimed to complement the existing analyses and identify novel markers using liquid chromatography-high resolution mass spectrometry-based foodomics strategies. In the discovery set, comparative untargeted metabolomics was utilized to identify marker candidates in microbially inoculated chicken eggs.

Hepatoprotective effect of Coreopsis tinctoria flowers against carbon tetrachloride-induced liver damage in mice.

Background: Coreopsis tinctoria is a traditional remedy for the management of various diseases including hepatitis. The hepatoprotective role of the plant is not scientifically explored till now. This study was designed to investigate the hepatoprotective potentials of the ethanol extract from C.

p-Hydroxyacetophenone suppresses nuclear factor-κB-related inflammation in nociceptive and inflammatory animal models.

p-Hydroxyacetophenone (HAP) is a crucial chemical compound present in plants of the genus Artemisia, which are used in traditional therapies for treating jaundice, hepatitis, and inflammatory diseases. Nevertheless, the bioactivity of HAP remains to be identified in order to prove its importance in the plants of genus Artemisia. This study investigated the antioxidative, antinociceptive, and anti-inflammatory effects of HAP, and probed its possible molecular mechanisms.

Simultaneous speciation of iron(II) and iron(III) by ion chromatography with chemiluminescence detection.

This study reports on a method for the speciation of iron in aqueous samples by the simultaneous analysis of divalent and trivalent iron ions with ion chromatography equipped with chemiluminescence detection (IC-CLD). Ferrous and ferric ions are first chelated by pyridine-2,6-dicarboxylic acid (PDCA) to form complexed anions, and separated by a mixed-bed ion-exchange column. The separated complexed ions are then detected with a CLD system containing luminol and hydrogen peroxide in a basic solution.

Determining eight colorants in milk beverages by capillary electrophoresis.

Milk beverages are popular because of their high nutritional value, and milk products that are enhanced with various fruit flavors are especially in high demand in Asia. Colorants are usually added to fruit flavored milk in order to increase its attraction and appearance, therefore, the detection and measurement of colorants in this type of beverage are relatively important for health issue reasons. Carminic acid, a natural colorant, along with tartrazine, Fast green FCF, Brilliant blue FCF, Allura Red AC, Indigo carmine, Sunset yellow FCF, and New coccine, which are seven different synthetic food colorants, are commonly used as food additives, therefore, this study would focus on the development of an analytical method for the detection of these common colorants in milk beverages.
