Miniaturized NIR spectroscopy and chemometrics: A smart combination to solve food authentication challenges

Over the years, technology has allowed more accurate, effective, and prompt food integrity assessments to assure quality authenticity of material. Thanks development portable hand-held near infrared (NIR) as a rapid, reliable, non-destructive, user-friendly instrument, on-site analysis is provided with feasibility. However, miniaturized NIR devices have some significant challenges due presence varying noise resources which can lead misinterpretation. In this context, chemometric methods capability resolution, identification, classification, calibration play pivotal role in achieving precise in-depth comprehension data. present mini-review, we will discuss instrumentation, concepts, introduce most popular algorithm authentication problem. The main feature review avoiding mathematical details much possible make material accessible broad audience but highlighting key features simple illustrative examples scope authenticity.
