    Notes: Filtrate flow through filter cakes which exhibits time dependent resistance was studied by measuring filtration rates through four types of perlite filter aids using a laboratory test system. Poultry chiller overflow water which has the potential for significant savings if recycled was used as the test suspension. Assumption of constant specific cake resistance and determination of its value from a plot of filtration rate against cummulative filtrate volume resulted in negative values for the medium resistance and large deviation between predicted and experimental values of filtrate volume particularly in the early stages of the filtration cycle. Equations were derived for independent determination of filtration medium resistance, which enabled determination of time dependent cake resistance factor. An equation which considered a time dependent cake resistance predicted values for filtrate volume which agreed well with experimental data. Data show that batch filtration of chiller overflow water will require very short cycle times for optimum filtrate flow.

    Notes: 3H-labeled S. typhimurium cells inactivated by gamma-radiation (60Co) and by formaldehyde (5%) were used to determine if cell viability affected attachment to poultry skin. Both gamma-irradiated and formal-dehyde-treated cells attached like live cells. There was no difference in attachment between cells grown in a chemically defined medium (SCDM) or in brain heart infusion broth (BHI). Live and gamma-irradiated cells and BHI-grown and SCDM-grown cells had similar surface hydrophobicity. Live and gamma-irradiated cells had similar cell surface charges, whereas BHI and SCDM-grown cells had different surface charges. Differences in cell surface charge did not affect attachment rate.

    Notes: Mixtures of ground chicken thigh meat and fat were formulated to contain 5, 10, 15, and 20% fat. Hunter color values, drip and cooking losses, proximate composition, texture profiles, and rates of microbial spoilage were compared for patties prepared from the mixtures. Raw patties became lighter and more yellow as fat content increased but cooking obscured these trends. As fat content increased, cooking losses and moisture:protein ratios increased. Lower fat patties were harder, springier, less cohesive and chewier than patties containing higher fat levels. Rates of bacterial spoilage were unaffected by fat content.

    Notes: In order to conserve water and energy the feasibility of fluming necks with treated bird chiller water instead of potable water was examined. No significant differences were found in shelf-life, total aerobic counts, levels of fecal coliforms, or salmonellae incidence between necks flumed with potable water and necks flumed with diatomaceous earth-filtered chiller water or filtered, chlorinated chiller water. It was concluded that the use of potable water is not essential in all phases of broiler processing and that necks could be flumed safely with either filtered chiller water or filtered, chlorinated chiller water.
