Assessing the feasibility of direct injection for pesticide residue analysis in grape juice by liquid chromatography/triple quadrupole mass spectrometry

In Brazil, the regulation of pesticide residues is guided by the National Health Surveillance Agency (ANVISA) and the Ministry of Agriculture and Livestock (MAPA), emphasizing the importance of monitoring pesticide levels in agricultural products to protect consumer health.

Study of intramolecular distribution of hydrogen isotopes in ethanol depending on deuterium content of water and the origin of carbohydrates

The paper presents the results of consistently developing studies carried out in 2022-2024 on the distribution of deuterium 2H(D) in intracellular water of grapes and wine products, taking into account the influence of natural, climatic and technogenic factors using high-resolution quantitative nuclear magnetic resonance spectroscopy 2H(D)-qNMR.
