2.3.2.2. Acceptance test of BO carried in salad dressing. As edible
oils are not usually consumed as such, the acceptance of BO as an
ingredient in salad dressing was assessed in a consumer test. A
formulation of homemade salad dressing was used to make two
sauces, using 90 mL of olive oil or BO. The remaining ingredients
were: tomato (40 g), onion (30 g), red wine vinegar (30 mL), fresh
basil leaves (10 g), garlic (2 g), salt (3 g) and black pepper (5 g). The
emulsions were made in a blender (Mondial, Appliance LTD MK,
Brasilia, Brazil). After been selected, washed and sanitized, ingredients
were added to the blender and processed homogeneously.
The dressings were film capped and stored at 10 C until
the acceptance test, which was carried out 2 h later. The dressings
were presented in randomized monadic sequence, in disposable
50 mL cups and at 20 C, with approximately 5 g of 5 mm strips of
lettuce on a white disposable plate so that the dressing was
poured over the lettuce at the time of tasting. The untrained assessors
(n ¼ 114) were regular consumers of salad dressings (at
least once a week), including students and staff of the Catholic
University of Brasilia. Samples were evaluated in the Laboratory of
Sensory Analysis, in individual booths.
