| Resumo: | Fruit processing for beverage production purposes is a way of adding value to the raw material and of raising the farmer s income by increasing the demand. Thus the objective of this work was the production of fermented West Indian cherry beverages and their physicochemical and sensory evaluation. The beverages were produced based on the Brazilian legislation for fermented fruit beverages and wine. The fermented beverages were produced from West Indian cherry pulp (pulper) and juice (press) and sweetened with sugar to obtain three types of beverage: dry, semidry and sweet. The beverages were submitted to the following physicochemical analyses: pH, alcohol, reducing sugars, total reducing sugars, total acidity, volatile acidity, fixed acidity, dry extract, reduced dry extract, alcohol to reduced dry extract ratio, free sulphur dioxide, total sulphur dioxide and turbidity. In the sensory analysis, the beverages were assessed using a 9-point hedonic scale, evaluating the attributes of appearance, odour, flavour and overall assessment. The chemical and sensory results were submitted to an analysis of variance and the means compared using Tukey s test (5%). Both the raw materials (pulp and juice) and the different sugar concentrations (dry, semidry and sweet) interfered in the sensory and physicochemical parameters of the fermented West Indian cherry beverages, the tasters showing preference for the sweetened beverages. |
