Effect of acid source on preference of CSPAll acids provide acidic taste but the sensorycharacter, intensity, and aftertaste are unique forthe individual acid (Dziedak, 1990). The degree oftartness of each acid has marked effect on the flavorof a product and governs the level in which it is usedin a given product. Each individual acidulant has aslightly different tartness. For example, the tartnessof citric acid is described as clean, while vinegar asastringent and tartaric as sharp or bitter (Gardner,1972; Sausville, 1974). Four different acid sources(kalamansi, lemon, tamarind and vinegar) were usedin four CSP samples. The amount of acid sourcesin the formulations was adjusted to reach the pH4.0 in the final product. The pH level was selectedbased on the most preferred pH level as mentionedin Table 2. The type of acid and the average scoreof ranking for each CSP sample is shown in Table 3.Results indicated that kalamansi juice had the highestscore and were most preferred as an acid source forCSP. However, in terms of taste, statistical analysisindicated that samples with kalamansi and lemonjuice were not significantly different (p<0.05) fromeach other but are significantly different (p<0.05)from CSP samples with tamarind and vinegar interms of taste. Since kalamansi is available in theSouth East Asia at a cheaper price than lemon, thesubsequent studies were conducted using CSP addedกับน้ำ kalamansi กรดซิตริกเป็นหลักการกรดอินทรีย์ใน kalamansi และที่พื้นมีกลิ่นเป็นการแทงจี้
