In the 1980's, studies that were conducted using sensory panels in California, Texas, Nevada and New York indicated that consumers preferred oranges above the 8:1 ratio and that raising the ratio might lead to increased purchasing (Ivans and Feree, 1987; Pehrson and Ivans, 1988). Even though SSC/TA is currently used to determine the minimum standard in California, it has been recognized that this measurement does not always correlate well with the perception of sweetness or tartness in the fruit (Jordan et al., 2001). (Jordan et al., 2001) recognizing that sugar and acid have the opposite effect on flavor and that the tongue is more sensitive to acidity, proposed subtracting TA from SSC after multiplying TA by a constant that differs by fruit type. This measurement index given the name BrimA, was found to be more closely related to flavor than SSC/TA.
