Metroxylon sagu
Metroxylon sagu is a tropical palm native to Southeast Asia and New Guinea. Its trunk stores starch that is extracted and processed into sago.
Sago: An edible starch product made from the pith of certain palms, especially Metroxylon sagu. This is the starch product for which the palm is chiefly cultivated.
Sago production: The process of extracting starch from palm pith and processing it into edible sago. It turns the palm’s stored trunk starch into a food product.
Sago cultivation: The planting and management of sago palms for starch, building materials, and other uses. Cultivation organizes the palm’s long growth cycle around its trunk-starch harvest.
Sago palm: A common name for palms in the genus Metroxylon, especially species cultivated for sago starch. The name commonly used for Metroxylon sagu in cultivation and food contexts.
Arecaceae: The botanical family of palms, a diverse group of flowering plants with usually unbranched stems. Metroxylon sagu belongs to this family of tropical palms.
Pith extraction: The removal of soft inner tissue from a plant stem for processing or use. Sago makers open the felled trunk and remove its starch-bearing pith.
Sago-based cuisine: Regional food traditions that use sago starch in staple dishes, snacks, and desserts. Sago from the palm is a traditional food across parts of Southeast Asia and New Guinea.
New Guinea: The world’s second-largest island, north of Australia, with extensive tropical forests and wetlands. The island is a major center of sago palm use and cultivation.
Palm pith: The soft tissue inside a palm stem, containing storage cells and vascular bundles. The trunk’s starch-rich pith is the material from which sago is extracted.
Starch gelatinization: The swelling and structural disruption of starch granules when heated with water. Heating sago in water gelatinizes its starch during cooking.
