Sago is basically a starch that is obtained from the sago palm (scientific name Cycas revoluta). Sago palm is known by several other names including sago cycad, king sago and Japanese sago palm. It is a gymnosperm species belonging to the family Cycadaceae. This plant has its origin in the southern regions of Japan counting the Ryukyu Islands. Actually, the sago palm is among the several species that is used to produce sago starch. Aside from yielding sago starch, this species is also grown in the form of an ornamental plant. Similar to several other starches, for instance potato or cornstarch, sago starch is employed in culinary as well as baking in the form of a thickener. In addition, this starch may also be employed for stiffening fabrics.
These days, sago palm is found growing widely in different regions of Southeast Asia and Papua New Guinea. Generally, the sago palm tree matures after 15 years and only then can its starch be used for food and other purposes. The starch is obtained by cutting down the tree and scooping out the pith or material inside the trunk. After scooping out the pith of sago palm, workers beat it manually using sticks or knives to remove the starch. Subsequently, they wet the pith and knead it to take out additional starch.
Having kneaded the wet pitch, the workers push the substance through a strainer, for instance squeezing the starchy water to remove the starch from the pith. The workers keep on squeezing the pith till the entire starch has been taken out. The water seeps away from the starch and it is accumulated in containers and left to dry out completely.
