NIRS calibration database on fresh mashed Matooke for color texture at NaCRRI IITA Uganda

This database contains 1312 NIR spectra of fresh mashed banana samples acquired in NaCRRI (Uganda) by using FOSS DS2500 NIR spectrometer. Banana bunches are harvested at the green-mature stage: when the finger angles are filled but before the fingers start ripening. Each bunch is labeled by genotype and bunch number. Cluster 2 of each bunch is used for acquiring the NIRS on the harvesting day, according to the protocol described in the SOP. Four random fingers of cluster 2 are selected and divided into two equal halves, giving a total of eight halves. Four of the 8 halves are first used for texture analysis using a TA.XT (Stable Micro Systems) texture analizer. The same samples are then mashed using a mottle and a pestle and used for NIRS acquisition. The remaining samples are used to estimate dry matter content, using an oven on 50 g of fresh matter. Cluster 3 of the same bunch is used for colour analysis using a chromameter (CR-400). This dataset combines NIRS spectra, texture and colour.
