The experimental design with independent variables and the
related observed responses for the extruded corn-shrimp snacks
prototypes are given in Table 2. Mixture response surface contour
plots (Figs. 1e3) display that the three independent factors, affect
sensory properties and bulk density of corn-shrimp snacks significantly.
Perturbation graph (Figs. 1e3) reveals that out of three independent
factors, factor “B” (X2: shrimp powder) plays a major
role in corn-shrimp snacks odor, flavor and the overall acceptance.
As the level of shrimp powder increased, the acceptance of the
product decreased. The acceptance scores indicate the degree of
dislike to liking and (Meilgaard et al., 2007) and shows how well a
prototype is liked by the experts/panelists. It can be used as a decision
making tool in food product development (Kristbergsson,
2001). However, there is no value for rejection to indicate a success
of a product. Therefore, using such data for product development
and prototype selection depends on specifications of the
product and expert panel comments (Shaviklo, Thorkelsson,
Sveinsdottir, & Pourreza, 2013). The perturbation graph (Fig. 1)
for flavor score reveals that all the three independent variables
