Tenderness classification of fresh broiler breast fillets using visible and near-infrared hyperspectral imaging.

Hongzhe Jiang, Seung-Chul Yoon, Hong Zhuang, Wei Wang, Kurt C Lawrence, Yi Yang,

The aim of this study was to classify and visualize tenderness of intact fresh broiler breast fillets using hyperspectral imaging (HSI) technique. A total of 75 chicken fillets were scanned by HSI system of 400-1000nm in reflectance mode. Warner-Bratzler shear force (WBSF) value was used as reference tenderness indicator and ... Read more >>

In-Package Inactivation of Pathogenic and Spoilage Bacteria Associated with Poultry Using Dielectric Barrier Discharge-Cold Plasma Treatments.

Michael J Rothrock, Hong Zhuang, Kurt C Lawrence, Brian C Bowker, Gary R Gamble, Kelli L Hiett,

The goal of this study was to test the efficacy of in-package dielectric barrier discharge-cold plasma (DBD-CP) treatment to inactivate poultry-associated spoilage (Pseudomonas fluorescens) and pathogenic (Salmonella enterica Typhimurium, Campylobacter jejuni) bacteria. Liquid cultures of the bacterial isolates were sealed within packages containing ambient air (Trial 1) or modified air ... Read more >>

Effect of Sample Preparation on the Discrimination of Bacterial Isolates Cultured in Liquid Nutrient Media Using Laser-Induced Breakdown Spectroscopy (LIBS).

Gary R Gamble, Bosoon Park, Seung-Chul Yoon, Kurt C Lawrence,

Laser-induced breakdown spectroscopy (LIBS) is used as the basis for discrimination between two genera of gram-negative bacteria and two genera of gram-positive bacteria representing pathogenic threats commonly found in poultry processing rinse waters. Because LIBS-based discrimination relies primarily upon the relative proportions of inorganic cell components including Na, K, Mg, ... Read more >>

Detection by hyperspectral imaging of shiga toxin-producing Escherichia coli serogroups O26, O45, O103, O111, O121, and O145 on rainbow agar.

William R Windham, Seung-Chul Yoon, Scott R Ladely, Jennifer A Haley, Jerry W Heitschmidt, Kurt C Lawrence, Bosoon Park, Neelam Narrang, William C Cray,

The U.S. Department of Agriculture, Food Safety Inspection Service has determined that six non-O157 Shiga toxin-producing Escherichia coli (STEC) serogroups (O26, O45, O103, O111, O121, and O145) are adulterants in raw beef. Isolate and phenotypic discrimination of non-O157 STEC is problematic due to the lack of suitable agar media. The ... Read more >>

Surface enhanced Raman scattering (SERS) with biopolymer encapsulated silver nanosubstrates for rapid detection of foodborne pathogens.

Jaya Sundaram, Bosoon Park, Yongkuk Kwon, Kurt C Lawrence,

A biopolymer encapsulated with silver nanoparticles was prepared using silver nitrate, polyvinyl alcohol (PVA) solution, and trisodium citrate. It was deposited on a mica sheet to use as SERS substrate. Fresh cultures of Salmonella Typhimurium, Escherichia coli, Staphylococcus aureus and Listeria innocua were washed from chicken rinse and suspended in ... Read more >>

Line-scan hyperspectral imaging system for real-time inspection of poultry carcasses with fecal material and ingesta

Seung Chul Yoon, Bosoon Park, Kurt C Lawrence, William R Windham, Gerald W Heitschmidt,

In poultry processing plants, fecal material and ingesta are the primary source of carcass contamination with microbial pathogens. The current practice of the poultry inspection in the United States is primarily human visual observations. Since the visual inspection is becoming more challenging in poultry processing plants adopting high-speed lines, a ... Read more >>

Classification and structural analysis of live and dead Salmonella cells using Fourier transform infrared spectroscopy and principal component analysis.

Jaya Sundaram, Bosoon Park, Arthur Hinton, Seung Chul Yoon, William R Windham, Kurt C Lawrence,

Fourier transform infrared spectroscopy (FT-IR) was used to detect Salmonella Typhimurium and Salmonella Enteritidis food-borne bacteria and to distinguish between live and dead cells of both serotypes. Bacteria cells were prepared in 10(8) cfu/mL concentration, and 1 mL of each bacterium was loaded individually on the ZnSe attenuated total reflection ... Read more >>

Comparison of FTIR spectra between Huanglongbing (citrus greening) and other citrus maladies.

Samantha A Hawkins, Bosoon Park, Gavin H Poole, Tim R Gottwald, William R Windham, Joseph Albano, Kurt C Lawrence,

Fourier transform infrared (FTIR) spectroscopy has the ability to quickly identify the presence of specific carbohydrates in plant materials. The presence of the disease huanglongbing (HLB) in the leaves of infected citrus plants has a distinctive spectrum that can be used to distinguish an infected plant from a healthy plant. ...

Detection of citrus Huanglongbing by Fourier transform infrared-attenuated total reflection spectroscopy.

Samantha A Hawkins, Bosoon Park, Gavin H Poole, Timothy Gottwald, William R Windham, Kurt C Lawrence,

Citrus Huanglongbing (HLB, also known as citrus greening disease) was discovered in Florida in 2005 and is spreading rapidly amongst the citrus growing regions of the state. Detection via visual symptoms of the disease is not a long-term viable option. New techniques are being developed to test for the disease ... Read more >>
