The aim of this research was to study the best quality of dried sweetened pineapple core with treatment of citric acid concentration and soaking time. A complete random design with two factors and three replications was applied in this research. The first factor was citric acid concentration (0.10%, 0.15%, and 0.20%) and second factor soaking time (36 hours, 45 hours, and 54 hours). The design response used was Duncan’s New Multiple Range Test (DNMRT) at the level 5%. Parameters observed were the moisture content, ash content, crude fiber content, acidity degrees (pH) content, total acid titration content, sucrose content, and sensory evaluation of description and hedonic (color, flavor, taste, texture, and overall assessment). The result showed that concentration of citric acid and soaking time significant has an interaction to acidity degrees (pH) content and sucrose content. Treatment with concentration of citric acid and soaking time have an effects to moisture content, acidity degrees (pH) content, total acid titration content, sucrose content, and sensory evaluation of description, and hedonic to color, flavor, taste, but not have an effect to texture and overall assessment. The best treatment of dried sweetened pineapple core was obtained from 0.15% concentration of citric acid and 36 hours soaking time with moisture content 19.94%, ash content 0.81%, crude fiber content 3.18%, acidity degrees (pH) content 4.36, total acid titration content 0.16, and sucrose content 47.09%. The best treatment has sensory evaluation of description with color is dark yellow (score 2.53), flavorful pineapple (score 4.26), quite sweet and sour of taste (score 3.53), hard textured (score 2.40), and overall assesment is preferred (score 4.32).
Keywords : citric acid, soaking time, pineapple core, dried sweetened.
