Abstract
Identifying nonallergenic, natural water binders to increase beef patty juiciness and extend shelf life would be beneficial to the beef industry. The objective of this study was to determine the effect of integrating water binders into beef hamburger patties on cooking yield, shelf life, and pH. Five water binder treatments were added at 2% of the meat block. Treatments included potato extract, citrus fiber, dried refried beans, potato peel, or no binder (control). Six batches of each treatment were made and two patties from each batch were analyzed for each parameter. Fluid yield and lipid oxidation were measured on cooked, frozen (210 d), and reheated patties. Raw patties were used to evaluate color, fluid loss, and lipid oxidation over 4 d of retail display. Patties containing citrus fiber improved reheat yield (P = 0.03) and overall yield (P < 0.01). Citrus patties had the lowest pH (P < 0.01) at 5.45. On days 0 and 4 of retail display, patties containing a water binder treatment had less lipid oxidation than the control patties (P < 0.01). Additionally, the cooked, frozen, and reheated patties, had less lipid oxidation when containing a water binder treatment than the control patties (P < 0.01). Citrus fiber improved water retention in reheated patties, and all water binders delayed lipid oxidation in raw, cooked, frozen, and reheated patties. Increasing patty juiciness and delaying lipid oxidation will improve consumers’ eating experience of reheated, precooked patties in settings such as school or hospital cafeterias.
