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...

Fast detection of toxic metals in crops is important for monitoring pollution and ensuring food safety. In this study, laser-induced breakdown spectroscopy (LIBS) was used to detect the chromium content in rice leaves. We investigated the influence of laser wavelength (532 nm and 1064 nm excitation), along with the variations of delay time, pulse energy, and lens-to-sample distance (LTSD), on t...

The vitality of corn seeds is a significant indicator for assessing the quality and yield crops. In recent years, numerous information technologies have been adopted to analyze seed provide support efficient equipment. However, there are still some shortcomings in these technologies, which decrease accuracy identifying various practical applications. this paper, synthesized classification metho...

Abstract Near Infrared Reflectance Spectroscopy (NIRS) is an alternative method that can be applied in the evaluation of feed ingredients. The purpose this study was to evaluate vitro digestibility value fermented cocoa pods using NIRS analysis. This used 18 samples shell waste, where material pod skin (KBK) then analysis carried out. Samples were acquired spectrum by Thermo Integrative. Chemic...

Reliable and user-friendly discrimination of coffee bean integrity quantification adulteration in the processing value chain would be vital for ensuring consumer trust quality control traceability management. In this research, a portable short-wave NIR spectroscopy coupled with chemometric data analysis was employed under different pre-treatments to develop rapid detection technique. Different ...

The study aimed on evaluating the feasibility of NIRS to predict sweetness and acidity of intact mango fruit in form of soluble solids content (SSC) and titratable acidity (TA) through calibration modeling. Diffuse reflectance spectra in NIR wavelength range of 1000 – 2500 nm were acquired for a total of 58 mango samples. PCR and PLSR were used to develop SCC or TA prediction models respectivel...

The quantitative description of the impact damage yellow peaches is an essential basis for evaluating their quality and guiding postharvest handling. In this study, combined hyperspectral technology mechanical parameters method were used to quantitatively investigate peaches. Firstly, parameters, which are damaged area, absorbed energy, maximum contact force, stress peaches, obtained by device....

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...

Diffraction and spectroscopic methods were evaluated for quantitative analysis of binary powder mixtures of FII(6.403) and FIII(6.525) piracetam. The two polymorphs of piracetam could be distinguished using powder X-ray diffraction (PXRD), Raman and near-infrared (NIR) spectroscopy. The results demonstrated that Raman and NIR spectroscopy are most suitable for quantitative analysis of this poly...
