Abstract
The Flash Profile is a descriptive analysis method derived from Free-Choice Profile, in which each taster chooses and uses his/her own words to evaluate the product while comparing several attributes. Four passion fruit juices were analyzed, two juices were produced with concentrated juice, one with pulp and one with reconstituted juice; all juices had different levels of sugar, some had gum and dyes. This study aimed to evaluate the physicochemical properties (color, titratable acidity and solid content) as well as sensory analysis like Flash profile and affective test. In physicochemical characterization and in Flash Profile, the juice A (pulp) had higher solid content and consistence, the juice B (concentrated juice) was the least acidic and presented the lowest value of soluble solids and presented strong aroma and flavor of passion-fruit, the juice C (reconstituted juice) was pale yellow and showed artificial flavor and the juice D (concentrated juice) was the most acidic, consistent with the natural flavor. In the acceptance test, all the juices scored 5-6, indicating that panelists tasters neither liked nor disliked. Flash Profile proved to be an easy and rapid technique showing a good correlation between panelists and the attributes and confirmed the results of physicochemical characterization.
Highlights
The Free-Choice Profile is an alternative method to enable panelists to be free to express themselves in descriptive terms, reducing the analysis time once it does not require previous training
Considering that the Free-Choice Profile concept is about tasters using the descriptors they wish, with no training or discussion with the panel, the procedure proposed for Flash Profile could be individualized and synthetized in only one session to allow larger panels with an approach concerning studies on consumers (DEHLHOLM et al, 2012; LASSOUED, et al, 2008; SANTOS et al, 2013; TERHAAG; BENASSI, 2010)
Physicochemical characterization pH was measured with a digital potentiometer and the titratable acidity was determined according to the AOAC (1995) methodology
Summary
The Free-Choice Profile is an alternative method to enable panelists to be free to express themselves in descriptive terms, reducing the analysis time once it does not require previous training. 337-344, July-Sept., 2015 which would enable them to change their individual list before the analysis In this way, all the members in the panel had to finish the first session in order to proceed with the analysis (final ordination session). Considering that the Free-Choice Profile concept is about tasters using the descriptors they wish, with no training or discussion with the panel, the procedure proposed for Flash Profile could be individualized and synthetized in only one session to allow larger panels with an approach concerning studies on consumers (DEHLHOLM et al, 2012; LASSOUED, et al, 2008; SANTOS et al, 2013; TERHAAG; BENASSI, 2010)
