This study investigated the use of whey protein, as an additional coating, in combination with basic, well-described predust, batter, and breading ingredients, for fat-uptake reduction in fried chicken. Chicken breasts were cut into strips (1 x 5 x 10 cm) and coated with wheat flour (WF) as a predust, dipped in batter, coated with WF as a breading, then dipped in 10% denatured whey protein isolate (DWPI) aqueous solution (wet basis). A WF-batter-WF treatment with no DWPI solution dip was included as a control. Coated chicken strips were deep-fried at 160 degrees C for 5 min. A Soxhlet-type extraction was performed to determine the fat content of the meat fraction of fried samples, the coating fraction of fried samples, raw chicken, and raw coating ingredients. The WF-batter-WF-10% DWPI solution had significantly lower fat uptake than the WF-batter-WF control, by 30.67% (dry basis).


This article describes applied research involving fat reduction in coated deep-fried chicken. The methods used in this article were intended to achieve maximized fat reduction while maintaining a simple procedure applicable to actual food processing lines.
