Feasibility of detecting aflatoxin B1 on inoculated maize kernels surface using Vis/NIR hyperspectral imaging.

Wei Wang, Gerald W Heitschmidt, William R Windham, Peggy Feldner, Xinzhi Ni, Xuan Chu,

The feasibility of using a visible/near-infrared hyperspectral imaging system with a wavelength range between 400 and 1000 nm to detect and differentiate different levels of aflatoxin B1 (AFB1 ) artificially titrated on maize kernel surface was examined. To reduce the color effects of maize kernels, image analysis was limited to ... 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 >>

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 >>

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 >>

Determination of In-Shell Peanut Oil and Fatty Acid Composition Using Near-Infrared Reflectance Spectroscopy

Jaya Sundaram, Chari V Kandala, Ronald A Holser, Christopher L Butts, William R Windham,

NIR reflectance spectroscopy was used to analyze the total oil and fatty acid concentration of Virginia and Valencia types of in-shell peanuts rapidly and nondestructively. NIR absorbance spectra were collected in the wavelength range from 400 to 2,500 nm using a NIR instrument. Average total oil concentrations of all samples ... 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 >>

Evaluation of activation of G proteins in response to thyroid stimulating hormone in thyroid gland cells from euthyroid and hyperthyroid cats.

Cynthia R Ward, William R Windham, Darrell Dise,

OBJECTIVE: To evaluate alterations in ligand-stimulated activity of G proteins in thyroid gland cells of hyperthyroid cats. SAMPLE POPULATION: Membranes of thyroid gland cells isolated from 5 hyperthyroid cats and 3 age-matched euthyroid (control) cats immediately after the cats were euthanatized. PROCEDURES: Isolated thyroid cell membranes were treated with thyroid-stimulating ... Read more >>

Two-dimensional correlation analysis of visible/near-infrared spectral intensity variations of chicken breasts with various chilled and frozen storages.

Yongliang Liu, Franklin E Barton, Brenda G Lyon, William R Windham, Clyde E Lyon,

Generalized two-dimensional (2D) correlation analysis of visible/near-infrared (NIR) spectra was performed to characterize the spectral intensity variations of chicken muscles induced by either storage time/temperature regime or shear force values. The results showed that intensities of two visible bands at 445 and 560 nm increase with the storage temperature under ... Read more >>

Prediction of color, texture, and sensory characteristics of beef steaks by visible and near infrared reflectance spectroscopy. A feasibility study.

Yongliang Liu, Brenda G Lyon, William R Windham, Carolina E Realini, T Dean D Pringle, Susan Duckett,

Color, instrumental texture, and sensory attributes of steaks from 24 beef carcasses at 2, 4, 8, 14, and 21 days post mortem were predicted by visible/near infrared (visible/NIR) reflectance spectroscopy in 400-1080 nm region. Predicting the Hunter a, b, and E* yielded the coefficient of determination (R(2)) in calibration to ... Read more >>

Rhizoma Peanut and Alfalfa Productivity and Nutrient Composition in Central Georgia

Thomas H Terrill, Seyoum Gelaye, Sauveur Mahotiere, Eugene A Amoah, Schauston Miller, Roger N Gates, William R Windham,

Limits of environmental adaptation of ‘Florigraze’ rhizoma peanut (Arachis glabrata Benth.), a high-quality perennial warm-season legume, have not been well defined. A field experiment compared yield and nutritive value of rhizoma peanut and alfalfa (L.) in central Georgia on a Norfolk soil (fine-loamy, siliceous, thermic Typic Kandiudults). Crude protein (CP), ... Read more >>
