This study was accomplished to determine the effects of egg yolk, egg white and sodium carbonate on textural properties of beef patties by using Central Composite Design of Response Surface Methodology. Meat patties were prepared using beef, lamb tail fat and spices. Effects of addition of egg yolk powder (0-1%), egg white powder (0-1%) and sodium carbonate (0-1%) on textural properties were studied by using a texture analyzer. The TPA and cutting force tests were measured in the samples. Effects of sodium carbonate were found to be significant (P<0.01) on springiness, hardness and cohesiveness values of beef patties. However, effects of egg white and egg yolk on the textural parameters were not found significant (P>0.05). The levels of sodium carbonate up to 0.72% improved the textural properties of beef patties.

This study was accomplished to determine the effects of sodium carbonate, egg yolk, and egg white powders on some of the physical-chemical and sensory properties of meat patties by using central composite design of response surface methodology. Meat patties were prepared using beef, lamb tail fat, and spices. Effects of the addition of egg yolk powder (0-1%), egg white powder (0-1%), and sodium carbonate (0-1%) on pH, proximate composition, cooking yield, and sensory properties were studied. The influence of egg yolk in the beef patties was found to be limited. However, the effects of egg white and sodium carbonate were found to be significant on several parameters. The levels of sodium carbonate up to 0.8% and egg white greater than 0.5% improved the physical-chemical and sensory properties of beef patties.
