Fat replacement by green banana biomass: Impact on the technological, nutritional and dynamic sensory profiling of chicken mortadella

Reducing the fat content of processed meat products has become necessary due to consumer-driven demand for healthier foods. In this sense, this study aimed to characterize chicken mortadella with total and partial replacement of chicken skin by green banana biomass (GBB). Five treatments (with two repetitions each and weighing 400 g) were prepared: F0 (control treatment formulated with 100% chicken skin), F1, F2, F3, and F4 (25, 50, 75, and 100% of chicken skin replacement by GBB, respectively). Samples were characterized according to physicochemical composition - approximate composition, energy value, pH, water activity (Aw), emulsion stability (ES), water-holding capacity (WHC), instrumental color (L*, a* and b*), instrumental texture, fatty acid profile, and microstructure) - nutritional quality and sensory properties (dynamic profiling by Temporal Checkall-that-apply and acceptance). The replacement of 100% chicken skin by GBB increased the WHC of mortadella and did not affect the ES in all formulations. The addition of GBB did not affect the typical mortadella flavor of the samples, and the dominance of the flavor was directed towards the fibrous and fat flavor attributes. In addition, all formulations had acceptance scores above 6.5. Based on the results, replacement up to 100% of chicken skin with GBB is possible and obtains a healthier emulsified meat product with good sensory acceptance.

Automated summary

The study found that replacing chicken skin with green banana biomass in chicken mortadella can increase the product's water-holding capacity and does not affect emulsion stability. The addition of green banana biomass does not alter the flavor of mortadella, and all formulations prepared have received good acceptance scores.
