Effects Of Adding Egg Powder From Hens Immunized Against Phospholipase Α2 On Ground Striploin Shelf Life, C. Velasco Ayala, L. A. Koulicoff, C. K. Chun, T. G. O'Quinn, E. Boyle, M. Richards, C. K. Jones, M. D. Chao
Kansas Agricultural Experiment Station Research Reports
Objective:The present study investigated the effect of incorporating three different levels of dried egg powder (EP) containing antiphospholipase α2 (aPLA2) on lipid oxidation and discoloration for its potential to extend ground striploin shelf life.
Study Description:U.S. Department of Agriculture choice striploins from ten beef carcasses were used. Impacts on beef discoloration, L* (lightness), a* (redness), and b* (yellowness) parameters, and lipid oxidation over a 7-day display period were studied. The fatty acid and phospholipid profiles of the beef patties were also examined.
Results:The EP was confirmed to contain active aPLA2. As expected, a* and b* values decreased …

Kansas Agricultural Experiment Station Research Reports
Objective:The objective of this study was to utilize a beef liposome model system to investigate if phospholipase-A2antibody (aPLA2) can be used to inhibit phospholipase-A2(PLA2) activity to potentially improve beef shelf-life.
Study Description:Phospholipids (PL) from 10 U.S. Department of Agriculture choice beef striploin steaks were extracted and split into six treatments: PL (25 mg of PL); aPLA10 (PL + 25 µg of aPLA2); aPLA20 (PL + 50 µg of aPLA2); PLA2 (PL + 10 µg of PLA2); PLA2+aPLA10 (PL + PLA2 + aPLA10); and PLA2+aPLA20 (PL + PLA2 + aPLA20). The model system was under …
