From: Using Near-infrared reflectance spectroscopy (NIRS) to predict glucobrassicin concentrations in cabbage and brussels sprout leaf tissue

Fig. 3

Near-infrared reflectance spectra from a desulphated glucobrassicin (GBS) potassium salt standard (solid line) and the average of all spectra from freeze-dried leaf tissue (n = 92) in the range of 950–1650 nm. Raw reflectance values a, first derivative values b, second derivative values c are represented. Leaf tissue samples were derived from cabbage and Brussels sprouts purchased from grocery stores and natural food cooperatives in Minneapolis and Saint Paul, MN between August and October, 2019
