First a, second b, and third c partial least squares (PLS) regression model factor loading values from the raw spectra model for predicting glucobrassicin (GBS) concentration from cabbage and Brussels sprouts. Vegetables were purchased from grocery stores and natural food cooperatives in Minneapolis and Saint Paul, MN between August and October, 2019. PLS regression models were developed to predict both fresh weight and dry weight GBS concentrations. Factor loading values from both models were the same so only one set is represented
