|
The purpose of this study was to determine the optimal mixing ratio of Gynura procumbens and milk in the preparation of beef patties. The experiment was designed according to the central composite design for estimating the response surface, demonstrating 10 experimental points including 2 replicates for Gynura procumbens and milk. The physical, mechanical and sensory properties of the test materials were measured, and a canonical form and perturbation plot were used to show the influence of each ingredient on the final product mixture. Results of the measurements showed significant increases or decreases in the following properties: dough moisture (p＜0.05); beef patty a (p＜0.001) and b (p＜0.001); hardness (p＜0.01), adhesiveness (p＜0.05), chewiness (p＜0.05), and gumminess (p＜0.05). In addition, the sensory measurements showed significant improvements in color (p＜0.001), flavor (p＜0.05), greasy (p＜0.05) and overall quality (p＜0.05). The optimum formulation calculated from the numerical and graphical analysis was 1.75 g Gynura procumbens and 20.44 g of milk.
