For the <strong>collection of NIR spectra<\/strong>, a transflexion approach was used with a reflector with an optical path length of 0.50 mm. <strong>Partial least squares regression<\/strong> (PLSR) was used to analyse the data and develop predictive models of quality characteristics.<\/p>\n\n\n\n<p>The <strong>results<\/strong> show that both the NIR scanner (1350-2500 nm, R<sup>2<\/sup> pre = 0.83-0.98 and RMSEP = 0.03-0.63) and the NIR sensor (1100\u20132550 nm, R2pre = 0.85-0.98 and RMSEP = 0.05-0.43) provide comparable performance with good merit parameters, highlighting their suitability for product quality assessment.<\/p>\n\n\n\n<p><strong>Overall<\/strong>, the study highlights the potential of miniaturised NIR systems as a cost-effective, high-throughput, multi-component monitoring technique for the tomato processing industry, optimising processes, improving production rates and increasing product quality. <\/p>\n\n\n\n<p><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><\/p>\n\n\n\n<p><strong>Bibliographical references<\/strong>: S.M.
