| Abstract: | Focused difference testing was applied to two orange juices prepared from frozen concentrate. Differences were noted between the juices for darkness of color, visual appearance of pulpiness, resistance to tongue movement, flavor by mouth, odor, overall taste and taste other than sweetness. The logic and approach of focused difference testing is discussed and contrasted with other sensory analytical techniques. |
