Acidic Organic Compounds in Wine

Grape pomace, a byproduct of the winery industry, holds various phenolic compounds within it. Scientists used liquid chromatography-based techniques to harvest these potentially beneficial components.

Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.

Shea kernels contain bioactive secondary metabolites that can offer potential health benefits. Researchers aimed to learn more about these substances.

Diflubenzuron and similar compounds can be signs of cattle fever ticks, which can cause morbidity in cattle. LC–MS/MS was recently tested as a means of detecting these disease-carrying insects.

Dimethylamine (DMA) is the smallest organic amine, typically being found in both humans and marine ecosystems. Dimitrios Tiskas of Hannover Medical School recently analyzed the nature and significance of DMA and other amines.

Chinese researchers created a new approach for identifying and quantifying illegal additives in fruit and vegetable plums, types of often-consumed health-care foods.
