    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

    Carotenoids - Infrared lock-in thermography - Laser photoacoustic spectroscopy - Near-infrared spectroscopy/chemometrics - Processed tomato - Spectrophotometry

    Carotenes found in a diversity of fruits and vegetables are among important natural antioxidants. In a study described in this paper, the total carotenoid content (TCC) in seven different products derived from thermally processed tomatoes was determined using laser photoacoustic spectroscopy (LPAS), infrared lock-in thermography (IRLIT), and near-infrared spectroscopy (NIRS) combined with chemometrics. Results were verified versus data obtained by traditional VIS spectrophotometry (SP) that served as a reference technique. Unlike SP, the IRLIT, NIRS, and LPAS require a minimum of sample preparation which enables practically direct quantification of the TCC.

    Infrared photothermal radiometry and inverse photopyroelectric method were used to determine thermal effusivity for tomato pastes characterised by a varying dry matter content. Unlike commonly adapted techniques, the two methods used here are reasonably fast and do not require the application of substantial external heat input; positive correlation between the effusivity and moisture content is high
