Article Title: Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry Combined with Chemometrics for Protein Profiling and Classification of Boiled and Extruded Quinoa from Conventional and Organic Crops

doi: 10.3390/foods13121906

Figure Lengend Snippet: Raw MALDI-TOF mass spectra for the protein extracts of ( a ) seed, ( b ) grain, ( c ) boiled, and ( d ) extruded V4 quinoa varieties from conventional farming (V4 = Salcedo). Different regions of the mass spectra are zoomed in for boiled and extruded quinoa.

Article Snippet: A 4800 MALDI TOF/TOF mass spectrometer (Applied Biosystems, Waltham, MA, USA) was employed to acquire mass spectra in mid-mass positive mode within a 3000–25,000 m / z range.

Figure Lengend Snippet: List of proteins detected by MALDI-TOF-MS used as variables for multivariate data analysis with their corresponding experimental M r , PLS-DA VIP score values for discrimination between farming and processing conditions, and tentative identifications. Theoretical M r , accession number (ID), and protein name were based on an experimental proteome map of the Salcedo samples obtained in a separate study by LC-MS/MS shotgun proteomics [ 47 ].

Article Title: Nutritional, molecular, and functional properties of a novel enzymatically hydrolyzed porcine plasma product

doi: 10.1371/journal.pone.0301504

Figure Lengend Snippet: MALDI-TOF mass spectra for the collected fractions of EHPP: (A) Fraction 1’ (measurement range 25,000–150,000 m/z in the high mass positive mode), (B) Fraction 2’ (measurement range 1,000–25,000 m/z in the mid mass positive mode) and (C) Fraction 3’ (measurement range 600–1,000 m/z in the low mass positive mode). Mass spectra are shown in the m/z ranges where peaks were detected. EHPP: Enzymatic hydrolyzed porcine plasma.

Article Snippet: MALDI-TOF mass spectra for EHPP fractions were obtained using a 4800 MALDI TOF/TOF mass spectrometer (Applied Biosystems, Waltham, MA, USA) as described in a previous work [ ].
