The actual work focuses onto the making fruit wine, blueberry and blackberry, with the aim to assess the physicochemical characteristics and the impact about sensory quality. It was used a completely randomized block design into a 2x2x2 factorial arrangement, by being factor A the fruit concentration; factor B, yeast activation temperature and factor C, soluble solids concentration, each factor with two levels, with a 8 treatments total. Into the fruit wine production soluble solids assessment (10.25°Bx); pH (3.14) and alcohol (9.55%), it was determined, which for soluble solids and alcohol, it is significant, in pH terms, it is not significant. The same way, it was assessed sensory quality into three phases: visual, olfactory and gustatory. The best treatment for the physicochemical characteristics, sensory quality and greater acceptability is the t6 treatment (50%blueberry-50%blackberry/35°C/23°Bx), by proceeding to perform the certified physicochemical analyzes into an external laboratory according to with the NTE INEN 374. Alcohol 9.62%; Total acidity 6.82 g/l; Volatile acidity 0.27 g/l; Total sulfur dioxide 676.56 mg/l; Methanol 63.46 mg/l and Sugar content 39.4 g/l. For sensory quality, it was determined into the visual phase, what it has a medium dark color; into the olfactory phase the primary odor is fruity, the secondary odor is to fermentation and the taste phase has a medium intensity, medium body, good harmony and long persistence. |
