Abstract
The craft beer segment has been driving the beverage market due to the many different formulation possibilities. Among craft beers, fruity beers provide the consumer with flavors previously unknown. In this sense, cape gooseberry is a tropical fruit known for its unique flavor, whose production is seasonal, which makes it difficult to use throughout the year. One possibility of incorporating cape gooseberry into fruity beers is to subject the fruit to freeze-drying, ensuring a constant stock of pulp. The present study aimed to produce a craft beer added with freeze-dried cape gooseberry, to add mineral compounds, phenolic compounds, and antioxidant activity to the final beverage. Three beer formulations with different concentrations of freeze-dried cape gooseberry (20, 40, and 60 g/L) were produced and characterized. The results showed that the addition of the fruit directly influenced the physicochemical parameters pH, Total Titratable Acidity (TTA), Total Soluble Solids (TSS), alcoholic concentration, color, bitterness, real extract, primitive extract, and turbidity. In addition, the beers with freeze-dried cape gooseberry showed an increase in the content of some minerals, total phenolic compounds, and antioxidant activity. Thus, the addition of cape gooseberry is a good option to improve the functional characteristics of the beer, providing a differentiated product.
