Short CV

Research Interests

Research activity of Beatrice De Giulio is focused on the  development and application of advanced analytical methodologies based on mass spectrometry in Food Science and Human Health areas. In particular her studies concern:

I) development and application of molecular profiling strategies based on MALDI-TOF mass spectrometry for food authentication, II) structural characterization of peptides and proteins by mass spectrometry, III) analysis of Volatile Organic Compounds (VOCs) by Solid Phase Micro-Extraction (SPME) coupled to GC-MS to investigate problems of food and clinical interest.

As molecular profiling strategies, rapid and reliable methods to define biomarkers of food authenticity by MALDI-TOF MS analyses have been applied in seafood analysis, in particular to species authentication, verification of commercial product authenticity and detection of fraudulent substitutions.

Structural analyses of peptides and proteins by mass spectrometry have been focused on characterization of tryptic peptides from bovine lactoferrin involved in the inhibition of herpes infection and analysis of haemoglobin peptides modified by epichlorohydrin and diepoxybutane, and are currently targeted to define modifications induced in gliadin peptides by site-specific deamidation and transamidation reactions catalyzed by tissue and/or microbial transglutaminase analyses by nano-HPLC–ESI-MS/MS.

Recently her research activity concerns also SPME GC-MS applications in food flavor analysis. These studies are focused on analysis volatile metabolites to obtain their “profile” in food or on target analysis of compounds that are either restricted, or known as important for quality, processing and storage.

SPME GC-MS strategies in clinical analysis are focused on study the VOCs profiles obtained from urine samples in order to evaluate the potential of the volatile metabolites in the diagnosing and treating of different diseases.
