Exploitation of endogenous protease activity in raw mastitic milk by MALDI-TOF/TOF.
TLDR
The proteic profiling of bovine milk produced by cows with subclinical mastitis was obtained by MALDI mass spectrometry, and results show a specific proteolytic activity of endogenous enzyme toward beta-casein precursor, alpha-S2- casein, and kappa-caseIn, which could allow the identification of either early markers of the acute phase of mastitis or endogenous peptide of innate immune response.
Statin-like principles of bergamot fruit (Citrus bergamia): isolation of 3-hydroxymethylglutaryl flavonoid glycosides.
TLDR
The 3-hydroxy-3-methylglutaryl neohesperidosides of hesperetin and naringenin were isolated and detected from the fruits of bergamot and the structures were determined by spectroscopic and chemical methods.
Assay of Sudan I contamination of foodstuff by atmospheric pressure chemical ionization tandem mass spectrometry and isotope dilution.
TLDR
A modern approach for assaying the content of this colorant in foodstuff down to a limit of a few tens of parts per billion, using the isotope dilution method combined with APCI tandem mass spectrometry.
Assay of the set of all Sudan azodye (I, II, III, IV, and Para-Red) contaminating agents by liquid chromatography-tandem mass spectrometry and isotope dilution methodology.
TLDR
A high-throughput mass spectrometric method is presented for the simultaneous detection of Sudan I, II, III, IV, and Para-Red azodyes in foodstuff using deuterium-labeled internal standards and atmospheric pressure chemical ionization in a triple-quadrupole instrument.
Profiling of hydrophilic proteins from Olea europaea olive pollen by MALDI TOF mass spectrometry.
TLDR
Results demonstrate that the proposed experimental procedure, can supply valuable information on the antigens' micro heterogeneity, and show that some of the features of protein structure and distribution probably depend on cultivar adaptation to the environment.
Determination of ketosteroid hormones in meat by liquid chromatography tandem mass spectrometry and derivatization chemistry
TLDR
The accuracy of the method was established by evaluating artificially spiked samples, obtaining values in the range 90–110 %, making this method competitive with current hormone assay methods.
Vinegar production to valorise Citrus bergamia by-products
In the bergamot (Citrus bergamia) processing cycle, peel and juice are the main by-products. Considering their high content in bioactive and aromatic compounds, the aim of this study was to valorise
