2.7.2. Sensory evaluation
Treated drumsticks were sensory evaluated immediately after
treatment or every 2 days during refrigerated storage until signs of
deterioration became evident. Sensory evaluation was performed
in raw treated drumstick or drumsticks cooked in a forced draught
oven at 220 C for 30 min according to the schemes of Sumarmono
and Rahardjo (2008), Baston and Barna (2010) and Kenawi (2005).
For sensory evaluation of treated drumsticks, nine experienced
panelists (from both sexes in the age range of 25e40 years) were
chosen from the staff members of the Department of Food Hygiene
and Control at Faculty of Veterinary Medicine, Cairo University,
Egypt. Panelists were selected on the basis of previous experience
in consuming dressed chicken. Moreover, they received a preparatory
session prior to testing, so that each panelist could thoroughly
discuss and clarify each attribute to be evaluated. The
panelists evaluated treated raw drumsticks in a randomized order
and asked to assign a numerical value between 1 and 7 for the
following attributes color, odor, slimness and texture where 1 is
very poor (I dislike it very much) and 7 is excellent (I like it very
much). After cooking, the panelists were asked to assign the same
numerical values for the following attributes: Color 1 (very poor) e
7 (excellent); Flavor 1 (imperceptible) e 7 (extremely intense);
tenderness 1 (extremely soft) e 7 (extremely tough) and juiciness 1
(extremely dry) e 7 (extremely moist). Tap water was provided
between samples to cleanse the palate. At the end of evaluation of
each cooked drumstick, each panelist was asked to give a score for
overall acceptability from 1 (dislike very much) to 7 (like very
much).
