Spectrophotometric and titrimetric methods for AA quantification. Linearity, precision, accuracy, limits of detection and quantification were evaluated using standard AA solution. Spectrophotometric method was more accurate (error <5%) for AA quantification in industrialized fruit juice. Titrimetric method had color juice interference resulting in errors >15%.
