Total appearance is inclusive of color + texture. The first
sensory impression of the quality of a food emulsion is its
overall appearance (e.g., its color, opacity, gloss and homogeneity)
(McClements and Demetriades 1998). Substitution
at 25 % did not cause significant difference with YC and EC
and even the score was higher than EC. The appearance
score of sample with 75 % substitution was lower likely
because of its color. In support to information reported by
McClements (2009), the data of the present study clearly
indicate that: the droplet size distribution of an emulsionbased
food product has a major impact on its physicochemical
and sensory properties, e.g., shelf life, appearance,
flavor, and texture.
Total acceptability is influenced by all attributes. YC
obtained the highest score affected by its color and thickness.
EC, 25 % and 50 %SM samples did not show any
significant difference in acceptability and as it was expected,
the least significant score was related to 75 %SM. According
to total acceptability scores, it can be concluded that
using soy milk up to 50 % of egg as emulsifier is accepted.
