Effect of acid source on preference of CSP
All acids provide acidic taste but the sensory
character, intensity, and aftertaste are unique for
the individual acid (Dziedak, 1990). The degree of
tartness of each acid has marked effect on the flavor
of a product and governs the level in which it is used
in a given product. Each individual acidulant has a
slightly different tartness. For example, the tartness
of citric acid is described as clean, while vinegar as
astringent and tartaric as sharp or bitter (Gardner,
1972; Sausville, 1974). Four different acid sources
(kalamansi, lemon, tamarind and vinegar) were used
in four CSP samples. The amount of acid sources
in the formulations was adjusted to reach the pH
4.0 in the final product. The pH level was selected
based on the most preferred pH level as mentioned
in Table 2. The type of acid and the average score
of ranking for each CSP sample is shown in Table 3.
Results indicated that kalamansi juice had the highest
score and were most preferred as an acid source for
CSP. However, in terms of taste, statistical analysis
indicated that samples with kalamansi and lemon
juice were not significantly different (p
