CSHLA Scholar Day

Introduction:

The surge of antibiotic-resistant bacteria has raised substantial concerns over how to effectively and efficiently control antibiotic-resistant bacteria capable of secreting biofilms. A biofilm can be defined as a self-producing extracellular matrix (Carter, et, al., 2016). Manuka honey, an alternative to conventional antibiotics, has proven successful in inhibiting planktonic cells and killing bacteria living under the protection of biofilms (Brudzynski & Sjaarda, 2015)

Effect Of Red Cabbage Extract On Minced Nile Perch Fish Patties Vacuum Packaged In High And Low Oxygen Barrier Films, Ayse Demirbas, Yavuz Yagiz, Ziynet Boz, Bruce A. Welt, Eric Mclamore, Maurice Marshall, William Pelletier, Amarat Simonne

Journal of Applied Packaging Research

Oxidation of polyunsaturated fatty acids (PUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in fish causes loss of product quality. Oxidative rancidity causes loss of nutritional value and undesirable color changes. Therefore, powerful antioxidant extracts may provide a relatively low cost and natural means to reduce oxidation, resulting in longer, higher quality and higher value shelf life of foods.

In this study, we measured synergistic effects of red cabbage antioxidant and vacuum packaging on lipid oxidation in fresh tilapia patties using thiobarbituric acid reactive substances (TBARS) assay, peroxide value (PV), pH and color analysis.

Concentrated red cabbage extract was obtained …

Glucans And The Poultry Immune System, Jacquie Jacob, Anthony J. Pescatore

Animal and Food Sciences Faculty Publications

With the reduced availability of antibiotics, poultry producers are looking for feed additives to stimulate the immune system of their birds. Some beta-glucans have been shown to improve gut health in poultry subjected to a bacterial challenge, to increase the flow of new immunocytes into the various lymphoid organs, to increase macrophage function, to increase antibody titers after a vaccination and to function as an anti-inflammatory immunomodulator. As a result, beta-glucans may provide a tool for producers trying to reduce or eliminate the use of antibiotics in poultry diets.

Reactivity Of Ketyl And Acetyl Radicals From Direct Solar Actinic Photolysis Of Aqueous Pyruvic Acid, Alexis J. Eugene, Marcelo I. Guzman

Chemistry Faculty Publications

The variable composition of secondary organic aerosols (SOA) contributes to the large uncertainty for predicting radiative forcing. A better understanding of the reaction mechanisms leading to aerosol formation such as for the photochemical reaction of aqueous pyruvic acid (PA) at λ ≥ 305 nm can contribute to constrain these uncertainties. Herein, the photochemistry of aqueous PA (5-300 mM) continuously sparged with air is re-examined in the laboratory under comparable irradiance at 38° N at noon on a summer day. Several analytical methods are employed to monitor the time series of the reaction, including (1) the derivatization of carbonyl (C═O) functional …
