Inativa??o bacteriana e sensorialidade em bebidas formuladas a partir de extrato reconstituído de Ocimum gratissimum L. (Alfavaca) - Labiatae - (Lamiaceae)

摘要

The activity intensity of bacterial inactivation (IINAB/bactericidie) on Salmonella Enteritidis (ATCC 11076) was determined in four drink formulations, two alcoholic and two no-alcoholic, with and without sugar, respectively, and in the reconstituted extract (alcoholature/green plant) of Ocimum gratissimum L. (African basil) - Labiatae - (Lamiaceae) at different concentrations (5, 15, and 30%) through suspension tests in multiple tube system. The acceptability/sensory preference of these four products was also determined using a hedonic scale. The bactericidal activity of all formulations against Salmonella Enteritidis was found to be directly proportional to the extract concentrations and the exposure time of the bacterium in the beverages, especially the non-alcoholic formulation with sugar. In the sensorial analysis, the preference increased with the decrease of the extract concentration of Ocimum gratissimum. The non-alcoholic beverage with sugar received the highest preference/acceptability score for the extract concentration of 5%.
