Fish species substitution is one of the most common forms of fraud all over the world, as fish identification can be very challenging for both consumers and experienced inspectors in the case of fish sold as fillets. The difficulties in distinguishing among different species may generate a “grey area” in which mislabelling can occur. Thus, the deve...

The sale of frozen–thawed fish and fish products, labeled as fresh, is currently one of the most common and insidious commercial food frauds. For this reason, the demand of reliable tools to identify the storage conditions is increasing. The present study was performed on two species, commonly sold in large-scale distribution: Cuttlefish (Sepia off...
Article
In this work, near infrared (NIR) spectroscopy and multivariate data analysis were investigated as a fast and non-disruptive method to classify green coffee beans on continents and countries bases. FT-NIR spectra of 191 coffee samples, origin from 2 continents and 9 countries, were acquired by two different laboratories. Laboratory-independent Part...
Article
Over the past decades, Red-Green-Blue (RGB) image analysis has gained increasing importance in industrial applications, since it has widely proved to be a suitable tool for food quality and process control. This article describes the development of a fast and objective method for the automated identification of defective hazelnut kernels based on m...
Article
In this study, for the first time, six different hazelnut cultivars, characterized by different carpological traits (diameter, volume, weight, density, shell thickness, shape index, empty volume between kernel and shell), were utilized for conducting 60 experiments in a lab-scale convective dryer, in which different drying air conditions (temperatu...
Article
The roasting colour of the coffee beans and the varietal composition of the blends are key factors for the development of the sensorial properties of the coffee brew. The former is a critical control parameter for the roasting process and allows to verify quickly the performance of the roasting, being directly related to the desired organoleptic ch...

La scelta della data di raccolta influisce profondamente sulla qualità finale dei frutti climaterici. Lo scopo di questo lavoro è quello di stimare il momento ottimale per la raccolta attraverso il monitoraggio del grado di maturazione dei frutti, effettuato direttamente sull'albero grazie alla messa a punto di strumentazione portatile. E' stato pr...

Questo lavoro è finalizzato a valutare l'applicabilità della spettroscopia nel vicino infrarosso (FT-NIR), associata a un'elaborazione multivariata dei dati, come metodo per determinare l'origine geografica del caffè verde. E' stato utilizzato un dataset di campioni di caffè verde,di cui vengono forniti il paese e la regione di provenienza. L'anali...
