Main objectives of this research were to develop the process and optimize condition for pectin extraction from Krueo Ma Noy leaves. Three types of leaves used in comparison were fresh leaves (without any treatment), sun-dried leaves and hot air oven leaves. The studied factors were temperature (30-90 deg C), time (30-90 mins.) and pH (2-8). The results showed that sun-dried and the hot air oven non-significantly (p GT 0.05) gave the highest yield of extracted pectin. Therefore, process with hot air oven was chosen due to the shortest time consumption in the preparing raw material. The optimum condition was mainly considered from the quantity and quality of extracted pectin. Obtained condition was temperature in the range of 68-75 deg C, pH of 2.0-2.8 for 42 mins. Yield of extraction pectin, galacturonic acid (GalA) content, methoxyl (MeO) content and degree of esterification (DE) were 35.32-42.21 percent, 67.04-76.83 percent, 2.62-3.28 percent and 28.00-29.97 percent, respectively.
