Sago palms (Metroxylon sagu) in New Guinea Peeling and pounding a segment of Sago Palm stem to produce an edible starch.Sepik River, Papua New Guinea. Sago (/ ˈ s eɪ ɡ oʊ /) is a starch extracted from the pith, or spongy core tissue, of various tropical palm stems, especially those of Metroxylon sagu. [1]
True sago palm is a suckering (multiple-stemmed) palm, each stem only flowering once (hapaxanthic) with a large upright terminal inflorescence. A stem grows 7–25 metres (23–82 feet) tall before it ends in an inflorescence. [3] Before flowering, a stem bears about 20 pinnate leaves up to 10 m (33 ft) long.
The pith contains edible starch, and is used for making sago. Before use, the starch must be carefully washed to leach out toxins contained in the pith. Extracting edible starch from the sago cycad requires special care due to the poisonous nature of cycads. [11] Cycad sago is used for many of the same purposes as palm sago.
'Queen sago' alludes to the name 'king sago' given to the related Cycas revoluta, as well as to its use as a source of edible starch.The specific epithet rumphii honours the German-born Dutch naturalist Georg Eberhard Rumphius (1628–1702), who served first as a military officer with the Dutch East India Company in Ambon, then with the civil merchant service of the same company.
A strainer used by Seminoles to extract an edible starch from coontie root. Indigenous tribes of Florida like the Seminoles and Tequestas would grind the root and soak it overnight; afterwards, they would rinse it with running water for several hours to remove the rest of the water-soluble toxin cycasin. The resulting paste was then left to ...
Sago starch extraction from palm stems. Starch is the most common carbohydrate in the human diet and is contained in many staple foods. The major sources of starch intake worldwide are the cereals (rice, wheat, and maize) and the root vegetables (potatoes and cassava). [41]
The starch contained inside the trunk is edible raw or cooked, as is the tip-top. The flowering stalks can be beaten to produce liquid. The nut kernels are also edible. [6] In Lamakera, its (ketebu) leaves are made into fibres weaved with sea hibiscus bark to make rope for whaling harpoons. [7]
The form of the starch after processing is similar to tapioca. Other foods sometimes mistakenly called piths include heart of palm (actually the core of the bud) and banana piths (actually the rolled up young leaves). The tiny central dark spot (diameter: about 1 millimeter (0.039 in)) in this yew wood is the pith.
