A carbonated beverage was produced from the guava fruit. The beverage was monitored at room temperature [20° - 25°C] for a period of 72 days. During this time the level of ascorbic acid fell from 35.1mg/100ml to 2.8mg/100ml. A second degree polynomial equation defines the degradation of ascorbic acid in the last half of this period Sensory evaluation of the product by a multiple comparison preference test with two commercial beverages was also made.
