Diets containing grape seed extract (GSE)-control, GSE [low GSE, low GSE + methionine, high GSE, and high GSE + methionine], or alpha-tocopherol-were fed to broiler chicks to estimate the antioxidative activity of GSE in processed meat. GSE was detrimental to the growth of chicks, and methionine did not reverse the detrimental effect. GSE with 85.4 g of(More)
Cholesterol has been used to monitor artifact generation. Stability differences among cholesterol oxide products (COPs) and cholesterol in thermal and alkaline conditions are theorized. Thus, use of cholesterol may be unsuitable for detection of artifacts generated from COPs. Stability of cholesterol was compared to that of 7-ketocholesterol (7-keto) and(More)
If freshly dried tomato pomace could be fed to poultry, its naturally occurring alpha-tocopherol would retard lipid oxidation during further processing, long-term frozen storage, and heating of poultry meat; however, the high fiber content in this agricultural by-product adversely affects its use. Experiments were conducted to investigate the chemical(More)
Tomato pomace, delignified by the edible oyster mushroom, Pleurotus ostreatus, could be used as a poultry feed ingredient to provide alpha-tocopherol for retardation of lipid oxidation in postmortem meat if the antioxidant were retained in pomace after fungal fermentation. Experiments were conducted to investigate changes in the content of alpha-tocopherol,(More)
Research was conducted to develop a more accurate and less time-consuming method of determining expressible moisture in poultry meat. Two modifications of wrapping meat in netting (fold wrap or basket wrap) were compared to a conventional method that did not include wrapping meat. Ground, dark poultry meat, with and without 2.0% added NaCl, was wrapped in(More)
Rabbit myosin subfragment 1 was allowed to react with malonaldehyde, a byproduct of lipid oxidation in a model system containing the subfragment 1 and malonaldehyde. The modified subfragment 1 was compared to the control, with use of sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), circular dichorism (CD), Fourier transform infrared(More)
A system is described that uses an oscillating magnetic field to produce power-frequency electric fields with strengths in excess of those produced in an animal or human standing under a high-voltage electric-power transmission line. In contrast to other types of exposure systems capable of generating fields of this size, no electrodes are placed in the(More)
The rapid SafTest PeroxySafe(™) MSA Kit (PeroxySafe method) was approved by the AOAC to determine peroxide values (PVs) in foods. Studies were conducted to remedy challenges (reaction time, lack of turbidity in samples, effect of prooxidant [NaCl]) for use of the method when analyzing PVs in turkey meat. Initially, PVs could not be consistently obtained(More)
The northern fowl mite (NFM),Ornithonyssus sylviarum, is the most common ectoparasite of laying hens in North America. Infestation can cause a reduction in egg production, egg weights, and feed conversion efficiency. However, there is a lack of information on the effects of NFM on hen physiology, physical condition, and egg quality. Singly caged(More)
