26. 3-2-1: Three NIR instruments, two fish species, one chemometric approach

Oral

Fish identification on the market can be very challenging for both consumers and experienced inspectors in the cases of fish sold as fillets (Acutis et al., 2019). In this field, reference, and gold standard analyses to identify animal species generally require rather long processing times, but quick decision-making is fundamental in preventing and counteracting frauds (Grassi et al., 2018)....

18. A moving-block-PCA based approach for real time monitoring of a powder blending process using a miniaturized near infrared sensor

Oral

Semen extenders (SE) are zootechnical products added to animal semen as diluent and preservative before artificial insemination procedures. A key-step of SE production is the blending phase; the definition of the process endpoint is, usually, done according to a specific blending duration, decided on experience bases.
Aim of the present work is the development of a strategy for the monitoring...

13. FT-NIR Analysis of Fatty Acid Ethyl Esters in Olive Oil

Poster

Guarantee of quality and commercial frauds are major concerns in the field of extra virgin olive oil. Among the chemical markers indicated by the European legislation (Reg.

EU 2011/61) is highly demanding in terms of time and...

11. FT-NIR spectroscopy for vinegar adulteration assessment

Oral

Vinegar is one of the food products most subjected to different types of frauds (Callejon et al., 2018). The most common fraud has a commercial character and it consists in the addition of a less economically valuable product, such as spirit vinegar, to authentic grape or apple vinegar. It is undoubtful that the detection of commercial frauds calls for non-destructive, rapid, and reliable...

28. Grape polyphenol content prediction through vis/NIR spectroscopy in a view of real time application at winery consignment

Oral

The evaluation of grapes at consignment is a crucial phase to obtain a qualitatively valid product, especially for large companies such as cooperatives, where the number of members is high, the vineyards are characterized by different pedological properties, growing techniques and cultivation methods. All these factors can lead to the production of grapes of the same variety with different...

27. Lipids in a nutshell: quickly assess the lipidic content in hazelnuts using NIR spectroscopy

Poster

Hazelnuts (Corylus avellana L.) are one of the most consumed dry fruits all over the world (Oliveira, et al., 2008). Their success is correlated with their nutraceutical properties, which show a high content in lipids with high nutritional value (Köksal, Artik, Şimşek, & Güneş, 2006). In the present work, we investigate the possibility of using near infrared (NIR) spectroscopy, using both an...

16. Measure your bratwurst: quantifying the content of mechanically separated meat by means of NIR spectroscopy and chemometrics

Oral

Any food chain can be affected by food frauds, from mislabelling to authentication counterfeiting. The meat chain is no exception: in the case of processed meat, especially when it is sold minced or in sausage form, it becomes very difficult to distinguish the different ingredients, therefore mislabelling and meat substitution can easily occur. This is especially true with the famous German...

8. Moisture content and water activity monitoring during solar drying pro-cesses with a portable NIR

22. Smart-HAND: a low-cost and portable visible/Near Infrared prototype for measuring qualitative parameters of fruits

Poster

Nowadays, controlling the ripening stage and quality of fruits has become crucial to obtain a high-quality finished product. Conventional ripening and quality analyses are destructive, subjective, time-consuming, and unsustainable because they often require chemicals and sample-preparation. The current methods are analytical chemical analyses and visual evaluations based on operator’s skills....

29. Strategies for non-linear modelling of NIR data

Oral

The growth of modern high-throughput instrumentation, which makes avaialble the relatively rapid characterization of samples by often multiplatform and/or multidimensional approaches, results in data that, if not always "big", anyway have a high extent of granularity, with different degrees of similarity and a general inhomogeneity due to many sources of variation, other than those of...
