Consumer acceptance of alternative plant-focused ingredients is increasing in the meat industry, with oat protein being used to increase yield and fat retention. Despite its positive effects on cook yield, inclusion of oat protein in ground beef patties may have a negative impact on color and tenderness.
The consumer acceptance of alternative plant-focused ingredients within the meat industry is growing globally. Oat protein is insoluble and used to increase product yield and fat retention. Furthermore, inclusion of oat protein can provide manufacturers another option for extending beef supplies. As the consumer diet shifts for improvements in nutritional density, oat protein is an alternative ingredient that lacks information on inclusion in a ground beef formulation. Coarse ground beef was allocated to one of four treatments, mixed with oat protein (0%, 1.5%, 3.5% and 4.5%), water, salt, pepper, textured vegetable protein, soy protein concentrate, and sodium tripolyphosphate. Meat blocks (n = 3 batches) were finely ground and formed into patties (N = 65/treatment). Patties were placed onto an expanded polystyrene tray, overwrapped with polyvinyl chloride film and displayed for 7 days. Instrumental color (L*, a*, and b*) decreased throughout simulated display (p = 0.0001). Increased usage rates of oat protein in patties resulted in greater cook yields (p = 0.0001). Objective measures of Allo-Kramer shear force values increased as oat protein inclusion rates increased (p = 0.0001). Oat protein can be incorporated in ground beef patties with positive effects on cook yield, but inclusion rate may have a deleterious impact on color and instrumental tenderness.
