Viability is an important quality factor influencing seed germination and crop yield. Current seed-viability testing methods rely on conventional manual inspections, which use destructive, labor-intensive time-consuming measurements. The aim of this study to distinguish between viable nonviable soybean seeds, using a near-infrared (NIR) hyperspectral imaging (HSI) technique in rapid nondestructive manner. data extracted from the NIR⁻HSI seeds were analyzed partial least-squares...

Spectroscopy has proven to be an efficient tool for measuring the properties of meat. In this article, hyperspectral imaging (HSI) techniques are used determine moisture content in cooked chicken breast over VIS/NIR (400–1,000 nm) spectral range. Moisture measurements were performed using oven drying method. A partial least squares regression (PLSR) model was developed extract a relationship between HSI spectra and content. full wavelength range, PLSR possessed maximum 0.90 SEP 0.74%. For...

As adulteration of foodstuffs with Sudan dye, especially paprika- and chilli-containing products, has been reported some frequency, this issue become one focal point for addressing food safety. FTIR spectroscopy used extensively as an analytical method quality control safety determination products. Thus, the use rapid dye in paprika powder was investigated study. A net analyte signal (NAS)-based methodology, named HLA/GO (hybrid linear analysis literature), applied to spectral data predict...

Monitoring the amount of active pharmaceutical ingredient (API) in finished dosage form is important to ensure content uniformity product. In this report, we summarize development and validation a hyperspectral imaging (HSI) technique for rapid in-line prediction microtablets with concentrations varying from 60 130% API (w/w). The tablet spectra different were collected using an HSI system within visible/near-infrared (vis/NIR; 400–1000 nm) short-wave infrared (SWIR; 1100–2500 regions....

Previous works indicate that data fusion, compared to single modelling can improve the assessment of soil attributes using spectroscopy. In this work, two different kinds proximal sensing techniques i.e., mid-infrared (MIR) and X-ray fluorescence (XRF) spectroscopy were evaluated, for seven fertility attributes. These include pH, organic carbon (OC), phosphorous (P), potassium (K), magnesium (Mg), calcium (Ca) moisture contents (MC). Three spectra fusion (SF) (spectra concatenation)...

The potential adulteration of foodstuffs has led to increasing concern regarding food safety and security, in particular for powdered products where cheap ground materials or hazardous chemicals can be added increase the quantity powder obtain desired aesthetic quality. Due resulting health threat consumers, development a fast, label-free, non-invasive technique detection over wide range is necessary. We therefore report rapid Raman hyperspectral imaging authenticity analysis. system...

The feasibility of a color machine vision technique with the one-class classification method was investigated for quality assessment tomato seeds. health seeds is an important factor that affects their germination rate, which may be affected by seed contamination. Hence, segregation healthy from diseased and infected seeds, along foreign materials broken to improve final yield. In this study, custom-built system containing camera white light emitting diode (LED) source adopted image...

Determining the quality of meat has always been essential for food industry because consumers prefer superior meat. Therefore, requires development a rapid and non-destructive method meat-quality determination. Over past few years, number techniques have presented monitoring meat–chemical attributes. However, most previous are quite expensive, destructive, require complex hardware to operate. Thus, in this work, we demonstrate low-cost sensing technique (eliminating expensive equipment...

Abstract. The objective of this study was to predict the moisture content (MC), soluble solids (SSC), and titratable acidity (TA) in bell peppers during storage (18°C, 85% relative humidity) over 12 days, based on near-infrared hyperspectral imaging (NIR-HSI) 1000-1500 nm wavelength range. mean spectra 148 mature were extracted from images, multivariate calibration models built using partial least squares (PLS) regression with different preprocessing techniques. most effective wavelengths...

The grading of ginseng (Panax ginseng) including the evaluation internal quality attributes is essential in industry for control. Assessment inner whitening, a major disorder, must be conducted when identifying high ginseng. Conventional methods detecting whitening root samples use manual inspection, which time-consuming and inaccurate. This study develops an measurement technique using near-infrared transmittance spectral imaging to evaluate samples. Principle component analysis (PCA) was...
