Based on wikipedia definition:
Sago is flour or processed that is derived from the processing of the lawn terrace or "sago Tree" (Metroxylon sago ROTTB.). Sago flour has physical characteristics similar to tapioca starch. In cooking recipes, sago flour that is relatively difficult to obtain is often substituted with tapioca starch so that its name is often exchanged, although both of these flour are different.
Sago is a staple food for the people of Maluku and Papua living on the coast. Sago is eaten in the form of Papeda, a kind of pulp, or other processed. Sago itself is sold as bulk flour and is compacted and packed with banana leaves. In addition, nowadays sago is also processed into noodles.
As a source of carbohydrates, sago is unique because it is produced in the swamp area (natural habitat of Rumbia). This condition has its own ecological advantages, although it is economically less profitable (difficult distribution).
Sago also can be used as Raw Material for Modified Starch industrial. Now, some of producer from Thailand did some research. They used Sago as raw material to produce Cationic Starch for paper industries application/
