Background: Licuri cake is a biodiesel byproduct and has been tested as an alternative feed additive for use in cattle production. This study analyzed the color, sensory and chemical attributes of burger meat from bovines. Thirty-two young Nellore bulls were used, housed in individual pens and distributed in a randomized experimental design with four treatments: no addition or the addition of 7, 14 or 21% (w/w) licuri cake in the dry matter of the diet.
Results: Interactions between the licuri cake level and the physicochemical variables (P > 0.05) were observed. Additionally, an interaction was observed between the licuri cake level and the burger beef color parameter lightness index (L*) (P = 0.0305). The L* value was positively and linearly correlated with the proportion of licuri cake in the diet of young bulls. The level of inclusion of licuri cake did not affect (P > 0.05) the sensory characteristics; the variables were graded between 6 and 7, indicating good overall acceptance.
Conclusion: Up to 21% (w/w) licuri cake can be included in the diet of young bulls without negatively impacting on beef burger quality. © 2015 Society of Chemical Industry.
