Rapid evaluation of grape phytosanitary status directly at the check point station entering the winery by using visibleear infrared spectroscopy

摘要

The aim of this work was to investigate the applicability of vis/NIR spectroscopy for rapid assessment of grape phytosanitary status, directly at the check point at grape consignment. A device for non-contact analysis at a distance between sensor and sample of 300 mm, in the spectral range 400-1650 nm was used. Acquisitions were carried out on healthy (1235 samples, 48%) and diseased bunches (1324 samples, 52%) from different white (Chardonnay, Grillo, Inzolia, Viognier) and red (Alicante, Nero d'Avola, Syrah) varieties.
