Analysis of the prospect of deep processing of cassava：

There are three main types of deep processing products of cassava starch: one is modified starch, which is widely used in textile, paper, medicine, food, building materials, foundry, light industry, petroleum, energy, feed, agriculture, environmental protection, bioengineering, etc. Chemical products, organic chemicals produced from cassava starch are alcohol, polyethylene, acetic acid, ethylene oxide, sorbitol, ethanolamine, citric acid, etc., which are important for the production of rubber, pesticides, oils, packaging, cosmetics, and military products raw materials, especially fuel ethanol, are added fuels in gasoline, and the market potential is considerable. The third is starch sugar, cassava starch can produce glucose, fructose, maltose, oligosaccharides, trehalose and other dozens of different sweetness of syrup, is an emerging health food, has a strong market competitiveness.

As an international trade product, cassava is mainly cassava chips and granules. The world's import and export volume is 6 million tons. At present, the annual output of world modified starch is close to 6.9 million tons, including about 3.4 million tons in the US, 2.6 million tons in the EU, and 360,000 tons in Japan, about 550,000 tons in Thailand and 350,000 tons in China. At present, the annual output of paper and paper products in the United States is 83 million tons, and the annual use of modified starch is 1.58 million tons, accounting for 2.3% of paper production. The annual output of paper and paper products in China is about 30.8 million tons, the starch costs is 160,000 tons. With the adjustment of the paper product industry's product structure, that is, the proportion of medium and high-grade paper products continues to grow, newsprint, cultural paper, office paper, copper paper, telecommunications paper, corporate paper and cardboard are long-term development varieties, so the amount of modified starch is also increasing, and the demand for cassava starch is also increasing. Modified starch is also used as a binder in feeds, it is used in an amount of about 25% of feed, and is also widely used in building materials, petroleum industry and pharmaceutical industry.
