Unbiased prediction errors for partial least squares regression models: Choosing a representative error estimator for process monitoring

期刊: JOURNAL OF NEAR INFRARED SPECTROSCOPY, 2023; 31 (4)

Partial least squares (PLS) regression is widely used to predict chemical analytes from spectroscopic data, thus reducing the need for expensive and t......

Determination of potential absorbance bands of fumonisin B1 in methanol with near infrared spectroscopy

期刊: JOURNAL OF NEAR INFRARED SPECTROSCOPY, 2023; 31 (4)

The contamination of maize, a major staple food in South Africa, with fumonisin B1 (FB1), has become a major food safety concern. The regulation of th......

Analysis of alkaloids and reducing sugars in processed and unprocessed tobacco leaves using a handheld near infrared spectrometer

期刊: JOURNAL OF NEAR INFRARED SPECTROSCOPY, 2023; 31 (2)

Near infrared (NIR) spectroscopy calibration models were developed to predict chemical properties of flue-cured tobacco (Nicotiana tabacum L.) leaf sa......
