Models for determining contents of soy products in ground beef were developed using near-infrared (NIR) spectroscopy. Samples were prepared by mixing four kinds of soybean protein products (Arconet, toasted soy grits, Profam and textured vegetable protein (TVP)) with ground beef (content from 0%–100%). NIR spectra of meat mixtures were measured with dispersive (400–2500 nm) and Fourier transfor...

Introduction I t is not possible to eliminate near infrared (NIR) spectroscopy as an analytical technique from our modern daily life. Flinn describes this very comprehensively and includes various application examples of NIR spectroscopy in his article titled “An average day (or how near infrared affects daily life)” in 2005. Applications of NIR spectroscopy in the minerals processing industry ...

Near-infrared (NIR) spectroscopy provides a rapid, non-destructive method for the routine estimation of wood properties. NIR spectroscopy is increasingly being used to replace traditional methods of wood property assessment, and it provides a wealth of information to tree growers, tree breeders, and manufacturers of forest products. The technology is particularly well-suited to tree improvement...

In this paper, NIR wheat quality quick detection system (NIR-WQDS) was developed on the base of grating technology with a scanning range of 900-1700nm.46 wheat samples were analyzed to compare performance of NIR-WQDS and MPA FT-NIR spectroscopy (MPA). Experiment results of NIR-WQDS show that the coefficient of determination R is 94.44%, root mean square error of cross validation RMSECV is 0.346...

Wheat hardness by near infrared (NIR) spectroscopy: New insights by Marena Manley The determination of wheat hardness by the evaluation of whole wheat grain would be of considerable value to the UK Milling Industry. Until now, accurate whole wheat grain hardness predictions by NlR spectroscopy have only been reported for North American wheats. By the evaluation of selected samples of UK and Nor...

Recently, non-destructive techniques such as the Vis / NIR spectroscopy have been used to evaluate the characteristics of maturation and quality of pears. The study aims to validate the readings by the Vis / NIR spectroscopy as a non-destructive way to assess the qualitative characteristics of pear cultivars 'Williams', 'Packams' and 'Carrick', produced according to Brazilian conditions. The ex...

The application of near infrared (NIR) spectroscopy for industrial process monitoring is achieving increasing importance over the last twenty years. In fact, the real time monitoring capacity of NIR spectroscopy is a very important feature for process monitoring, prediction and control as it allows a fast evaluation of the state of the process. However, the application of NIR spectroscopy in wa...

The goal of this study was to characterize the changes in biomass with torrefaction for near infrared reflectance (NIR) and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy for sweetgum, loblolly pine, and switchgrass. Calibration models were built for the prediction of proximate analysis after torrefaction. Two dimensional (2D) correlation spectroscopy between NI...
