INTRODUCTION
Durian is a seasonal fruit that most popular in Southeast Asia, particularly Malaysia,
Indonesia, Thailand, and Philippines [16]. Central Bureau of Statistics of the Republic of Indonesia
states that the average durian production increased from 17,405 tons in 1999 to 741,831 tons in
2003, and by the end of 2011 to 883,969 tons. Only a third of the durian fruit are edible, while the
seed (20-25%) and the skin is usually discarded. Utilization of durian seed is still limited.
According to research [2], durian seed can be used as a thickener because of the content of
hydrocolloid (water-solube gum).
