Introduction
Viviana Polizzi graduated as Master in Food Science and Technology at the University of Catania (Italy). After obtaining her PhD ‘Research on fungal growth and production of volatile fungal metabolites in relation with the sick building syndrome’ at the Faculty of Bioscience Engineering of Ghent University, Viviana worked for 6 years as an analytical chemist at the R&D Centre Europe of Cargill (GC-MS/FID, FTIR). From March 2018, she joined VITO, where she is contributing to different research projects with focus on the development of membrane separation processes for purification/concentration and fractionation of lignin-based streams issued from pretreatment processes and lignin depolymerization and aiming at enabling commercial production of bioaromatics.

Lignin, a by-product of the pulp and paper industry, that is traditionally extracted from wood in order to produce cellulose, is the most abundant natural source of aromatics on Earth. As such, it shows potential in polymer design, in which currently, the majority of the used resources are still fossil-based. Not only can lignin replace existing ha...
The synthesis of novel, renewable lignin‐based protective films with anticorrosive properties is presented in this work. Thermosetting films are prepared by means of tandem UV‐initiated thiol‐yne “click” synthesis and Claisen rearrangement strategy. These films contain high lignin loading, 46–61%, originating from a birch wood reductive catalytic f...
Lignin is a renewable and abundant source for production of bio-based chemicals and is a valuable alternative to crude oil to obtain aromatic building blocks. It is built from aromatic units with strong chemical linkages, which need to be cleaved to enable the use of the aromatic compounds in industrial applications. In addition to depolymerizing l...
In the last decades, the increasing reporting of non-specific symptoms experienced by the occupants of a building with poor indoor air quality, such as headache, nausea and irritation of skin, eyes and airways, has brought about the neologism Sick Building Syndrome (SBS). The causative agents of SBS are not identified but indoor dampness is consist...
Alkylpyrazines are a very important class of Maillard flavor compounds, but their mechanism of formation is complex and consists of different pathways. The model reaction of 20 different amino acids with 1,3-dihydroxyacetone, as a precursor of 2-oxopropanal, was studied by means of SPME-GC-MS to investigate the involvement of the amino acid side ch...
