Sažetak
A large global industry of banana (Musa spp.) generates the high quantity of byproduct- banana peel, representing approximately 30 % of the fruit. Potential applications of banana peel depend on its chemical composition. Due to the valuable bioactive content of banana peel, the objective of this study was to develop alginate-pectin- and alginate/pectin- based edible films containing banana peel extracts and to characterize their physical (colour, solubility, thickness, dry matter) and mechanical (firmness and elasticity) properties, bioactive potential and release kinetics of bioactives from films in simulated gastrointestinal conditions. Among differently prepared banana peel extracts (conventional and ultrasound assisted extraction, acid hydrolysis, decoction and maceration), conventionally prepared extract (30 min, 80 ºC) was used in the formulation of edible films due to the highest total phenolic content (TPC) (19.08±0.35 mg GAE/g dw) and antioxidant capacity (AC) determined by ABTS assay (0.11±0.00 mmol TE/g dw). According to the values of physical- mechanical properties and determined prolonged release of TPC and AC in simulated gastrointestinal conditions, alginate- based edible film was the best evaluated. The obtained results indicate the promising application of banana peel extract in the formulation of bioactive enriched delivery systems.
