Use of plasma proteins in beef patties with different fat content

Abstract

This study aimed to evaluate the effect of fat and plasma in the characteristics of beef patties, after frying, such as: yield, shrinkage and release of fat, and also to evaluate the interaction between the factors of color of the product before frying. 3 levels of fat were evaluated (17%, 10% and 5%) and also 3 levels of plasma (0%, 5% and 10%) in a 3x3 factorial. The treatments with higher concentrations of fat (17%) behaved in a positive manner in relation to yield (85,59%) and showed a negative effect on the shrinkage (27,75%), and a greater release of fat (3,54 %). The plasma acted positively to either cooking loss (87,02%) and shrinkage (24,49%). The plasma had no effect on the release of fat. Fat influenced a more intense coloring of the beef patties in the parameters L*, a* e b*. The plasma influenced the color on some levels of fat.
