This paper describes the application of mid-infrared (MIR) spectroscopy and partial least-squares (PLS) analysis to predict concentration organic carbon fractions present in soil. The PLS calibrations were derived from a standard set soils that had been analysed for total (TOC), particulate (POC), charcoal (char-C) using physical chemical means. calibration models this allowed prediction TOC, POC, char-C with coefficient determination (R2) measured v. predicted data ranging between 0.97...

This paper reports on the development of a rapid and simple method for red wine authenticity confirmation during transport processing; namely, "fingerprinting" system. When is transported between two sites, sample taken mid-infrared (MIR) spectrum obtained. One hundred sixty-one (n = 161) samples three main varieties grown in Australia, Shiraz, Cabernet Sauvignon, Merlot, were collected from six commercial wineries across Australia scanned transmission MIR spectrophotometers located at The...

Soil composition and preparation can affect prediction accuracy using diffuse reflectance mid-infrared Fourier transform spectroscopy (DRIFTS). In the present study, we evaluated effect of soil composition, carbonate content on particle size distribution (PSD) predictions in four contrasting sets soils, including calcareous partial least-squares regression (PLSR). The soils were scanned as <2- <0.1-mm fine-ground samples. Regression calibrations derived for individual sets, well a...

The effect of homogenisation and storage on both the visible (Vis) near infrared (NIR) spectra as well calibration performance for measurement total anthocyanins (colour), soluble solids (TSS) pH in red grapes were investigated. Homogenates obtained from fresh previously frozen (overnight freezing 24 hours, after one, three, six 12 months storage) scanned reflectance mode (400–2500 nm) using a monochromator instrument (Foss NIRSystems 6500). Principal component analysis was used to examine...
