To achieve the Seabuckthorn juice brand non-destructively, we put forward a fast identify method based on Visible_near infrared reflectance (NIR) spectroscopy . We use the Field Spec 3 spectroradiometer to collect 40 sample spectra data of the three kinds of Seabuckthorn juice separately. the sample data was preprocessed by Using of average smoothing method and multiplicative scatter correction...

Detection rapidity and model accuracy are the keys to hyperspectral nondestructive testing technology, especially for Pennisetum sinese Roxb (PsR) due its extremely high adsorptive heavy metal content. The study of resolution PsR is conducive analysis accumulated content in different parts. In this paper, contents Cd, Cu Zn old leaves, young upper stem, middle stem lower as well data correspond...

Abstract Cocoa pods husk (CPH) fermented can be used as an alternative animal feedstuff. Near-infrared (NIR) spectroscopy has been shown in order to determine the nutritional contents of CPH fermented. This study aims assess characteristics NIR raw spectra and pretreated for chemomectric model. The spectrum pretreatments include multiplicative scatter correction (MSC), Savitzky-Golay smoothing ...

Near-infrared spectroscopy (NIRS), a rapid and efficient tool, was used to determine the total amount of nine ginsenosides in Panax ginseng. In the study, the regression models were established using multivariate regression methods with the results from conventional chemical analytical methods as reference values. The multivariate regression methods, partial least squares regression (PLSR) and ...

The development of NIRS calibration model as a rapid, precise, robust, and cost-effective method to estimate oil content in ground seeds of worldwide safflower germplasm collection grown under different agro-climatic conditions was the key objective of this research project. The oil content was measured by accelerated solvent extraction method in a total of 328 samples collected across 2004 (16...

Chili (Capsicum annuum L.) is an important source of total carotene and vitamin C. Both substances are widely used in food processing materials, supporting a healthy immune system medicine. However, destructive testing often obtains information about the substances, which damages tested material requires relatively long analysis. Therefore, this research aims to develop calibration models C chi...

Remote sensing data play a crucial role in precision agriculture and natural resource monitoring. The use of unmanned aerial vehicles (UAVs) can provide solutions to challenges faced by farmers managers due its high spatial resolution flexibility compared satellite remote sensing. This paper presents UAV spectral datasets collected from different provinces South Africa, covering crops at the fa...
