Online seminar by Giulia Gorla: ' Rapid Analysis of Milk Using Low-Cost Pocket-Size NIR Spectrometers and Multivariate Analysis' (Lecture)

Wednesday 14 October 2020Add to my calendar
from 11:00
Online via Zoom (link will be provided upon registration)
Giulia Gorla, University of Insubria, Como, Italy

In the talk, we will discuss about the issues and methods applied during the work which led to the publication "Rapid Analysis of Milk Using Low-Cost Pocket-Size NIR Spectrometers and Multivariate Analysis" (Riu, J.; Gorla, G.; Chakif, D.; Boqué, R.; Giussani, B. Foods 2020, 9, 1090).

In this study, we have evaluated the capabilities of two recently developed portable NIR instruments (SCiO and NeoSpectra) to achieve a rapid, simple and low-cost quantitative determination of commercial milk macronutrients. A selected set of milk samples was chosen to emulate the whole commercial milk population and a careful evaluation of different instrumental set up was conducted. Then, data preprocessing methods were studied, and multivariate calibration was used to correlate the recorded spectra with the macronutrient content of milk.

The miniaturisation of analytical devices, the reduction of analytical data acquisition time, or the reduction of waste generation throughout the analytical process are important requirements of modern analytical chemistry. However, even if miniaturized near-infrared spectroscopy (NIR) systems have an important role in the future of in situ and online analysis their use has to be based on a compromise between the performance parameters (accuracy and sensitivity) and the requirements of green analytical chemistry.
