Fermented umbu-flavored goat milk: elaboration and acceptance

Abstract

In this study, a fermented umbu-flavored goat milk was developed, and its acceptance was evaluated aiming at achieving an alternative for making use of goat milk and umbu marmalade. The fermented milk production stages consisted of milk measuring, addition of powdered milk and modified starch, thermal treatment, cooling, inoculation into starter culture, fermentation, cooling, curdled milk split, and umbu marmalade addition. Three different products were made with different quantities of umbu: Sample A, 25%; Sample B, 27%; and Sample C, 30%. Sensorial characteristics were assessed by potential consumers, and the samples were randomly served, in a monadic form, the same number of times, in the same presentation order. The attributes received good rankings, which corresponded to the hedonic scale of “I slightly liked it” and “I liked it moderately”. No significant difference among the samples acceptance was found. The variation of 2.5% in the umbu marmalade contents did not affect the sensorial qualities of fermented milk. The fermented goat milks were in compliance with the Brazilian legislation for products made from cow milk. Goat milk showed to be a good option for dairy industries; however, further studies should be performed to get products with improved sensorial characteristics.
