“…Rungpichayapichet, Mahayothee, Nagle, Khuwijitjaru, and Müller () used a portable VIS‐NIR photo‐diode array spectrometer (HandySpec Field 1000, tec5AG) to study mango fruit quality and maturity and good results were reported for SSC prediction, standard error of prediction (SEP) of 1.2% and a correlation coefficient ( R 2 ) of 0.90, for firmness prediction (SEP of 4.22 N and R 2 of 0.82), and for TA prediction (SEP of 0.38% and R 2 of 0.74). Marques, Freitas, Pimentel, and Pasquini () studying ‘Tommy Atkins’ mangoes used a portable MicroNIR 1700 to predict SSC, DM, TA, and firmness with low root mean square error of prediction (RMSEP), 0.92°Brix, 0.51%, 0.17%, and 12.2 N, respectively. Santos Neto, Assis, Casagrande, Cunha Júnior, and Teixeira () reported the use of a portable F‐750 to predict DM in ‘Palmer’ mango with good results, root mean square error of crossvalidation (RMSE CV ) of 8.3 g.kg −1 and RMSE cv of 8.8 g.kg −1 with a of 0.86 and of 0.84.…”
