摘要：Reduced fat mayonnaise has the disadvantage of destabilization of emulsion. Emulsion destabilization that occurs is the separation of oil and water. Pumpkin flour is used to increase the viscosity and stability of the emulsion. The objective of this study was to determine the best percentage of the use of pumpkin flour in reduced fat mayonnaise based on pH, emulsion stability, moisture content, and sensory evaluation. The material used in this research was mayonnaise made from egg yolk, canola flower oil, vinegar, pumpkin flour as a fat replacer carbohidrates based, and other optional ingredients. The method used was an experimental laboratory with a completely randomized design with 4 treatments and 4 replications. The treatments consisted of without the use of pumpkin as a control, the use of pumpkin flour 2%, 4%, and 6% of the total oil used. The variables measured were pH, emulsion stability, moisture content, and sensory evaluation. The results showed that the use of pumpkin flour on mayonnaise gave highly significant effect on pH, stability emulsion, moisture content and increased panelists preferences. The conclusion of the study that using 6% pumpkin flour produced the best reduced-fat mayonnaise.
