Growing consumer demand for value-added foods has accelerated the emergence of fortified products enriched with biologically active compounds. Fruit juices, commonly fortified with vitamins, minerals or plant-based extracts, represent a major segment of this market. However, the assurance of authenticity and compositional integrity of such products remains challenging, particularly in the absence of rapid, non-destructive analytical methods. The joint Austria–Hungary project aims to establish spectroscopy-assisted quality control tools for fortified fruit juices, combining near-infrared (NIR), infrared (IR) and Raman spectroscopy with advanced chemometrics. This multidisciplinary collaboration seeks to deliver reliable, non-invasive analytical solutions for industry, promoting consumer protection, reducing food fraud and supporting sustainable waste recycling through the valorisation of plant-based by-products.
