The banana (Musa spp.) is a tropical fruit with excellent sensory characteristics in terms of aroma, flavor and texture, consumed worldwide and exploited in most tropical countries. Green banana flour is rich in flavonoids, which protect the gastric mucosa, has a high content of resistant starch, which acts in the body as a dietary fiber and thus has health benefits, and is an alternative option for bakery products, reducing waste of both the peel and the pulp. The aim of this study was to develop bread formulations with partial substitution of wheat flour with green banana flour (FBV), thus increasing the nutritional, technological and sensory value. 4 formulations, (A), standard sample; (B), bread with 10% FBV; (C), bread with 15% FBV and (D), bread with 20% FBV. Physico-chemical quality was assessed in terms of moisture content by drying at 105ºC, ash by incineration, fat by the Soxhlet method, protein by the biuret method, carbohydrates by difference calculation and calorific value by sum calculation and sensory analysis by affective methods. The data was evaluated using the RStudio 4.2.1 DCC statistical package. There were no significant differences in moisture content, lipids and calorific value. Differences were evident in the ash and protein content. Sensory acceptance of the standard formulation was 82.22%. The results obtained show that green banana flour can be used as a partial substitute for wheat flour to produce breads with functional properties.

Fiber characteristics of Musa balbisiana, Musa paradisiaca and Musa sapientum pseudo-stalks were investigated. Fiber characteristics such as fiber length, fiber diameter, lumen width, and cell wall thickness were measured in the macerated banana pseudo-stalk by microscopy. Slenderness ratio, flexibility coefficient (%) and Runkel ratio were also determined from these microscopic measurements. Mean value of the properties evaluated for Musa sp. respectively were as follows: Fiber length- 2.96mm; Fiber diameter- 21.71µm; Lumen width- 13.55µm; Cell wall thickness- 3.86µm; Flexibility ratio- 66.35%; Runkel ratio- 0.66 and Relative fiber length- 159.12. Based on the findings of this study the Musa sp. pseudo stalk is suitable for pulp and paper production due to its high quality of fibers.
