Carbonated apple juice could benefit from trends toward natural foods, demand for convenience, and increasing soft drink consumption. To determine acceptability and storage stability of carbonated apple juice, two studies were conducted. Eighty-four lunchtime customers of a university cafeteria ranked 90 pairs of samples of plain and carbonated apple juice on a 7-point hedonic scale. Carbonated juice was preferred by 32.1%, uncarbonated by 66.7% and 1.2% had no preference. A taste panel of 8-10 people evaluated chilled coded samples for appearance, taste and overall acceptability using a 9-point hedonic scale after 0, 3, 8, 12, and 18 weeks of storage. Average hedonic ranks fell between 5 and 7, reflecting comments that the juice was too sweet. Overall acceptability decreased slightly by 3 weeks. Laboratory analysis of CO-2 volume, percent soluble solids, color, and vitamin C level showed no changes due to storage that were considered to be of practical importance.
