metadata.artigo.dc.description.abstract: The aims of this work were to elaborate a fruit wine from cagaita (Eugenia dysenterica DC) pulp and to compare the fermentations conducted with free and with Ca-alginate immobilised cells. Two strains of Saccharomyces cerevisiae (UFLA CA11 and CAT-1) were tested and four fermentation batches were performed, in triplicate, at 22 °C for 336 h: UFLA CA11 in free and immobilised cells and CAT-1in free and immobilised cells. Fermentation time and ethanol production were influenced by the yeast strain and by the cell status, with immobilised cells of UFLA CA11 and CAT-1 fermenting faster (4 days and 8 days, respectively) than UFLA CA11 and CAT-1 free cells (10 days and 12 days, respectively). Ethanol content (g/L) was slightly higher when the fermentation was conducted with free cells (94.63 and 94.94 for UFLA CA11 and CAT-1, respectively) than with immobilised cells (86.82 and 87.21 for UFLA CA11 and CAT-1, respectively). The beverage from CAT-1 free cells showed the highest concentration of higher alcohols (82,086.12 μ/L), whereas the lowest concentration (37,812.17 μ/L) was found in the beverage from immobilised UFLA CA11. The ethyl ester concentration ranged from 1511.42 μ/L (CAT-1 free cells) to 2836.34 μ/L (UFLA CA11 free cells). According to the sensory evaluation, the fruit wine acceptability was greater than 70% for colour, flavour and taste for all cagaita beverages.
