Evolution of free amino acids and volatile compounds in dry‐cured fermented 'salchichón' sausages superficially inoculated with different molds

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Surface molds contribute to flavor development in dry‐cured fermented sausages through their effects on proteolysis, amino acid catabolism, and volatile compound formation. This study evaluated the influence of Aspergillus oryzae, Penicillium camemberti, Penicillium roqueforti and Penicillium nalgiovense on the evolution of free ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.
