Due to climate changes and Xylella fastidiosa infection the production of Italian extra virgin olive oil (EVO) recentely decreased. Italy now imports oils from other countries to meet the needs of the consumers and the food industry. As a consequence, an increase of frauds based on the mixture of the Italian EVO oil with those produced by other countries in Europe or outside Europe has been...

Deep frying is one of the most common processes used in food industry. Oils producers companies need to assess the maximum frying cycles to retain the quality of certain types of oils. Near Infrared Spectroscopy has demonstrated its ability to predict physico-chemical parameters in a broad range of raw and frying oils (Garrido et al., 2004). This work aims to study the degradation of different...

Bee pollen is a natural product rich in many nutritional compounds, but it could be contaminated with pyrrolizidine alkaloids (PAs) that can cause acute and chronic toxicity in humans. These toxins has been detected by time-consuming and expensive analytical chemistry techniques. Therefore, NIRS could be used as an alternative for the detection of PAs contamination. For this purpose, NIR...

The most frequently used functional neuroimaging methods in educational research are electro-encephalography (EEG) and functional magnetic resonance imaging (fMRI) (van Atteveldt et al., 2018), which have provided many insights into brain function during learning and teaching. While each method brings different advantages, studies using these imaging techniques are low in ecological validity,...

Egg industries are more and more interested in non-destructive and rapid methods for the assessment of freshness and quality of shell eggs. Some studies showed that NIR spectroscopy is a valid technique to determine shell egg freshness (Lin et al., 2011) and internal quality parameters (Abdanan Mehdizadeh et al., 2014). However, poor attention has been given to the method development and none...
