2.7. Sensory evaluation of jam
A selected group of 10 assessors (made up of 5 females and 5 males, aged between 24 and 50 years old), previously involved as members of the trained descriptive analysis panel for jams, was trained to describe the attributes of carrot jams. All evaluation sessions were held in the laboratory at the Institute of Sciences of Food Production. The sensory evaluation of carrot jams was carried out 2 days after jam making. Color, taste, odor, consistency, and overall acceptability of each carrot jam were evaluated using a hedonic scale from 9 to 1 (9 ¼ like extremely, 8 ¼ like very much,7 ¼ like moderately, 6 ¼ like slightly, 5 ¼ neither like nor dislike,
4 ¼ dislike slightly, 3 ¼ dislike moderately, 2 ¼ dislike very much,
1 ¼ dislike extremely) (Basu & Shivare, 2010; Grigelmo-Miguel & Martín-Belloso, 1999). All jams were presented to the panellists at room temperature under normal lighting conditions in transparent plastic glass coded with random, three-digit numbers. Each pan- ellist evaluated 24 samples (4 carrot jams 3 replications 2 methods). The sensorial test was divided into sessions, in which the panellists evaluated 3e5 samples at a time, working in individual booths and drinking water for oral rinsing. The average value scores of all sensory evaluations were used in the analysis.
