Feasibility study for the surface prediction and mapping of phytonutrients in minimally processed rocket leaves (Diplotaxis tenuifolia) during storage by hyperspectral imaging

•Reliable quantification of Vitamin C in rocket leaves using NIR.•First derivative followed by mean centering served as best pretreatment.•Average vitamin C represented by pixels within calibration range decreased with time.•Detected pixels within calibration range decreased with the passage of stor...
