The name sago is also sometimes used for starch extracted from other sources, especially the sago cycad, Cycas revoluta. The sago cycad is also commonly known as the sago palm, although this is a misnomer as cycads are not palms. Extracting edible starch from the sago cycad requires special care due to the poisonous nature of cycads. [6]
The tree is of commercial importance as the main source of sago, a starch obtained from the trunk by washing the starch kernels out of the pulverized pith with water. A trunk cut just prior to flowering contains enough sago to feed a person for a year. [4] Sago is used in cooking for puddings, noodles, breads, and as a thickener.
Other methods included the use of sago starch. [2] The advent of cellulose dopes such as "Emaillite" was a major step forward in the production of practical aircraft, producing a surface that remained taut (eliminating the need for frequent re-covering of the flying surfaces) [ 3 ]
The starch industry extracts and refines starches from crops by wet grinding, washing, sieving and drying. Today, the main commercial refined starches are cornstarch, tapioca, arrowroot, [38] and wheat, rice, and potato starches. To a lesser extent, sources of refined starch are sweet potato, sago and mung bean.
The pith of the sago palm, although highly toxic to animals in its raw form, is an important human food source in Melanesia and Micronesia by virtue of its starch content and its availability. There is a simple process of starch extraction from sago pith that leaches away a sufficient amount of the toxins and thus only the starch component is ...
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. Sago is extracted from the sago cycad by cutting the pith from the stem, root and seeds of the cycads, grinding the pith to a coarse flour and then washing it carefully and ...
Sago is a common and essential part of Papua New Guinean cuisine, [3] as the starch ingredient is included in several traditional dishes, such as pancakes and pudding. Sago is in the form of flour usually extracted from the palm tree. Staples of the Papua New Guinean diet include karuka, sweet potato (kaukau), cassava, breadfruit (ulu), and ...
Depending on the variety and the growing conditions, it may take a sago tree five to over ten years to accumulate enough starch in its trunk to make the effort of extracting it worthwhile. [4] Papeda is made by cooking sago starch with water and stirring until it coagulates and becomes more translucent. It has a glue-like consistency and ...
