- Optimization and use of concentrates allowed high ethanol yields in fruit wines.
- Fermentation behavior was well described by mathematical models.
- Fruit wines, mainly orange and cherry, presented antioxidant activity.
- Wines produced maintained fruit distinctive chemical composition.
- Fruit wines produced from concentrates were well accepted by trained panelists.
This work presents an optimized approach alongside with the mathematical models describing the production of fruit wines, using fruit concentrates as an alternative to attain the desired ethanol yields and enhance organoleptic and functional properties. Box-Behnken design was used for modeling and optimization of ethanol yield and productivity in banana, orange, cherry and mango concentrates fermentations. Optimization allowed ethanol yields of 72.3 ± 2.08 g·Lâ1 in orange, 101 ± 1.78 g·Lâ1 in mango, 66.1 ± 4.02 g·Lâ1 in cherry and 98.2 ± 7.88 g·Lâ1 in banana with maximal productivities of 0.4 ± 0.0 g·Lâ1·hâ1, 1.0 ± 0.1 g·Lâ1·hâ1, 1.7 ± 0.2 g·Lâ1·hâ1 and 1.0 ± 0.1 g·Lâ1·hâ1, respectively. Evaluation of total antioxidant activity by FRAP demonstrated fruit wines potential for the development of foods and formulations with functional properties, attaining 22.6 ± 0.46 mmol·Lâ1 for orange, 7.14 ± 0.77 mmol·Lâ1 for mango, 28.0 ± 1.84 mmol·Lâ1 for cherry and 9.54 ± 0.89 mmol·Lâ1 for banana wines. Characterization of aroma active compounds was performed by GC-MS and sensory evaluation by trained panelists. All fruit wines had good acceptance with cherry wine presenting the highest overall preference, followed by orange, mango and banana wines. Correlation between chemical and sensory properties was established with PLSR2 between analytical and sensory data, which allowed an insight of chemical composition impact in consumer perceived quality.
