Onulin, fructooligosaccharide, oat fiber and wheat fiber were added at 3 and 6% level in low-fat beef burger and their performances were evaluated. The low-fat beef burgers were submitted to cooking losses, objective color, texture profile, TBARS value, pH, microbiological and sensory evaluations. FR3, FR6, ON3 e ON6 showed no difference from the control to yield. Hardness values increased in DF6, WF3 and WF6 and it was similar to control. WF6 was the lowest score for the overall acceptance. Higher yield and hardness were found with the addition of insoluble fibers at 6% level. The TBARS values were not influenced by the addition of dietary fibers in low-fat beef burger. Onulin at 6% (ON6) level showed the highest score for all the sensory attributes. Adding 6% inulin was shown the best alternative for use in low-fat beef burger.Keywords: dietary fiber; acceptability; fat substitute; TPA; inulin. Practical Application:Comparison of technology behavior of soluble and insoluble fiber as fat substitute in beef burger.

Sodium chloride in meat products provides microbiological stability and desirable technological and sensory effects. Therefore, the reduction of this ingredient is a challenge for the meat industry. The objective of this study was to evaluate the physicochemical and sensory characteristics of ready-to-eat sliced frozen roast beef with partial replacement of sodium chloride by a commercial additive mostly composed of potassium chloride. The analyses performed were chemical composition, cooking yield and post defrosting loss, microbiological evaluation and sensory analysis. There was higher moisture content (p < 0.05) in the control treatment (without the presence of the replacement additive) and all treatments were not different (p ≥ 0.05) in the cooking yield and in post-defrosting loss. The results of microbiological analysis are according to Brazilian Legislation. The sensory evaluation showed no difference between the control treatment and the T1 treatment (with the reduction of 35% of NaCl), while the T2 treatment (with reduction of 70% of NaCl) had the lowest average values in all attributes. The study showed that the reduction of 35% NaCl for commercial additive, mostly composed of potassium chloride, in roast beef is feasible since no changes were observed in sensory and technological characteristics evaluated.
