Edible starch made from carbohydrates stored in the trunks of several palm trees. The main raw materials are two kinds of sago palms, Metroxylon rumphii and M.sagu, which originated in Indonesia. Sago palms grow in low marshes, usually 9 meters high and thick. /kloc-after 0/5 years, a flower ear grows, and the stem pith is full of starch. When the fruit is formed and ripe, it absorbs starch and hollows out the stem. When the fruit is ripe, the trees will die. Cut the cultivated sago palm when the flower heads appear, take out the pulp containing starch and grind it into powder, add water and knead the wood fiber above the filter, and wash it several times to get sago rice flour, which can be eaten on the spot. Sago transported abroad is made into paste by adding water, and then kneaded into particles with a sieve, and divided into pearl sago or meatball sago according to the particle size. Sago is almost pure starch, containing 88% carbohydrate, 0.5% protein, a little fat and a little vitamin B. In the southwest Pacific, sago is the main food, and its coarse powder is used to make soup, cake and pudding. Around the world, the main way to eat is to make pudding or sauce thickener. Used as hardener in textile industry. On Selan Island in Borneo, Indonesia, Simi palm forest covers a huge area. Simi produced in Borneo is imported to Europe in large quantities, and the planting area is also expanding due to the increasing demand. Other Indonesian palms are also the source of sago, such as Tanya Arenga pinnata, Caryota urens and vegetable palm Coryphaumbraculifera. There are two kinds of sago palms in South America, namely sago in Mauritius and Guilielma gasipaes. Now most supermarkets sell white balls. Well, they are more like Wuji Baifeng Pills, but not as bright as them. The practice is: take a lot of blisters, soak them in boiling water, and stir while cooking. Turn off the fire when you see that most of them only have white stones, so it's stuffy. When there are no white stones, pour them into cold water and then you can eat them.
