The authenticity determination of white rice is crucial to prevent deceptive origin labeling and dishonest trading. However, a non-destructive comprehensive method for rapidly discriminating the geographical origins between countries still lacking. In current study, we developed volatile organic compound based discrimination using headspace solid-phase microextraction coupled gas chromatography-mass spectrometry (HS-SPME/GC-MS) discriminate samples from Korea China. A partial least squares...
Whole-cell Systemic Evolution of Ligands by Exponential enrichment (SELEX) is the process which aptamers specific to target cells are developed. Aptamers selected whole-cell SELEX have high affinity and specificity for bacterial surface molecules live targets. To identify DNA Staphylococcus aureus, we applied our rapid method a single-stranded ssDNA library. improve selectivity aptamers, designed, selected, developed two categories that were kinds SELEX, mixing combining FACS analysis...
A Tungsten-Halogen (TH) lamp is the most popular light source in NIR spectroscopy and hyperspectral imaging, which requires a warm-up to reach very high temperatures of up 250 °C take long time for radiation stabilization. Consequently, it has large enough volume enable heat dissipation prevent thermal runaway electric circuit turn out its power efficiency low. These are major barriers miniaturizing spectral systems imaging devices. However, TH lamps can be replaced by pc-NIR LEDs order...
In this study, we developed a viability evaluation method for pepper (Capsicum annuum L.) seeds based on hyperspectral reflectance imaging. The spectra of in the 400–700 nm range are collected from images obtained using blue, green, and red LED illumination. A partial least squares–discriminant analysis (PLS-DA) model is to classify viable non-viable seeds. Four spectral ranges generated with four types LEDs (blue, red, RGB), which were pretreated various methods, investigated develop...
For the authentication of white rice from different geographical origins, selection outstanding discrimination markers is essential. In this study, 80 commercial samples were collected local markets Korea and China discriminated by mass spectrometry-based untargeted metabolomics approaches. Additionally, potential that belong to sugars & sugar alcohols, fatty acids, phospholipids examined using several multivariate analyses measure their efficiencies. Unsupervised analyses, including...
Biofilms formed on the surface of agro-food processing facilities can cause food poisoning by providing an environment in which bacteria be cultured. Therefore, hygiene management through initial detection is important. This study aimed to assess feasibility detecting Escherichia coli (E. coli) and Salmonella typhimurium (S. typhimurium) using fluorescence hyperspectral imaging. E. S. were cultured high-density polyethylene stainless steel coupons, are main materials used facilities. We...
This research aims to design and fabricate a system measure the capsaicinoid content of red pepper powder in non-destructive rapid method using visible near infrared spectroscopy (VNIR). The developed scans well-leveled surface continuously minimize influence placenta distribution, thus acquiring stable representative reflectance spectra. incorporates flat belts driven by sample input hopper stepping motor, leveler, charge-coupled device (CCD) image sensor-embedded VNIR spectrometer, fiber...
is a common fungal disease in grains that reduces the yield of barley and wheat. In this study, near infrared reflectance spectroscopic technique was used with statistical prediction model to rapidly non-destructively discriminate grain samples contaminated
Contamination is a critical issue that affects food consumption adversely. Therefore, efficient detection and classification of contaminants are essential to ensure safety. This study applied visible near-infrared (VNIR) hyperspectral imaging technique detect classify organic residues on the metallic surfaces processing machinery. The experimental analysis was performed by diluting both potato spinach juices six different concentration levels using distilled water. 3D hypercube data were...
Rapid visible/near-infrared (VNIR) hyperspectral imaging methods, employing both a single waveband algorithm and multi-spectral algorithms, were developed in order to discrimination between sound discolored lettuce. Reflectance spectra for lettuce surfaces extracted from reflectance images obtained the 400-1000 nm wavelength range. The optimal wavebands discriminating determined using one-way analysis of variance. Multi-spectral algorithms ratio subtraction functions resulted enhanced...
Meat consumption has shifted from a quantitative to qualitative growth stage due improved living standards and economic development. Recently, consumers have paid attention quality safety in their decision purchase meat. However, foreign substances which are not normal food ingredients unintentionally incorporated into These should be eliminated as hazard or safety. It is important find fast, non-destructive, accurate detection technique of substance the meat processing industry....
Non-destructive methods based on fluorescence hyperspectral imaging (HSI) techniques were developed to detect worms fresh-cut lettuce. The optimal wavebands for detecting the investigated using one-way ANOVA and correlation analyses.
Geographical origin discrimination of white rice is an important endeavor in preventing illegal distribution and regulating standardizing food safety quality assurance. The aim this study was to develop a method for geographical between South Korean Chinese using hyperspectral fluorescence imaging technique multivariate analysis. Hyperspectral images samples were obtained the wavelength range 420 nm 780 with intervals 4.8 365 ultraviolet-A excitation light. Partial least squares discriminant...
