Abstract
Six commercial Florida‐packed frozen concentrated orange juice samples drawn from the U.S. retail market on a monthly basis for 1 yr were evaluated for sensory attributes, color (by colorimeter), Brix, acid, and bottom pulp. Consumers rated flavor “like moderately” on a 9‐point hedonic scale for every sample. The degree of sweetness and tartness of samples was “just right;” bitterness was somewhat excessive and color was somewhat too light (P < 0.05). Generally, as the °Brix to % acid ratio increased, the flavor improved, and the closer to “just right” was the degree of sweetness, tartness, and bitterness. A significant amount of bitterness was perceived as tartness or lack of sweetness (P < 0.01). Plant‐to‐plant variation was found in ratings of flavor and colorimeter color and °Brix to % acid ratios.
