What is the development status of Modified Starch industry and the market price of modified starch? At present, China's denatured starch industry has transitioned from traditional low-value products to high-end products and rich variety structure to strive to meet the high-end demand of the market. However, the current single product and low value are still the main reasons restricting the industrial development. The consumer market still has great potential which has not been fully developed. After industrial transformation and upgrading, it will still be a sunrise industry with great potential.
Modified starch is to change the structure of starch particles through physical, chemical and biological methods to make it have new properties. Modified starch is also called modified starch, modified starch and starch derivatives. The upstream of the modified starch industry chain includes corn starch, cassava starch, wheat starch and potato starch; Its downstream market is mainly used in the fields of textile, paper, food, feed, casting, medicine, construction and petroleum.
There are many kinds of modified starch and its application is very wide, so there are many classification methods. According to the modification methods of modified starch, it can be divided into physical denaturation, chemical denaturation, enzymatic denaturation and compound denaturation. According to the production route of modified starch, it can also be divided into dry method, wet method or organic solvent method, extrusion method or roller drying method. It can also be classified according to the sources before starch denaturation, such as potato denatured starch, corn denatured starch, wheat denatured starch, etc. According to the application or function of starch, there are also oxidized starch, acid hydrolyzed starch, cross-linked starch, cationic starch, phospholipid starch, carboxymethyl starch, carboxyalkyl starch, etc.
The commonly used modified starch in textile processing includes acid hydrolyzed starch, cationic starch and compound modified starch. These modified starches have the characteristics of reducing the viscosity of the slurry, increasing the fluidity and permeability of the slurry. The modified starch commonly used in food processing includes cross-linked esterified starch, hydroxypropyl starch, hydroxypropyl cross-linked starch, etherified starch, etc. by improving the heat resistance, hydrophilicity, anti-aging and film formation of starch, the food has satisfactory quality.
In terms of output, the production of modified starch in China fluctuates due to the restrictions of raw materials and environmental protection. In recent years, the total output has basically stabilized at about 1.7 million tons. In 2020, the output of modified starch in China will reach 1751100 tons, basically the same as that in 2019.
Among the modified starch varieties in 2020, the varieties with an output of more than 100000 tons include compound modified starch, oxidized starch, cationic starch, acetate starch, phosphate starch and pre gelatinized starch, with an output of 360200 tons, 320600 tons, 228100 tons, 197100 tons, 155900 tons and 115800 tons respectively. The output of these six products accounts for 83.54% of the total output of modified starch.
Compared with last year, the output of oxidized starch and compound modified starch increased significantly, with a year-on-year increase of 14.68% and 12.82% respectively The output of phosphate starch and acetate starch decreased by 25.75% and 8.79% respectively.
The domestic modified starch raw materials are mainly corn starch, sweet potato starch and cassava starch. Therefore, the production area of modified starch basically coincides with the main production area of starch. Shandong is the largest province of modified starch production in China. In 2020, the output of modified starch in Shandong Province will reach 671400 tons, accounting for 38% of the total output. In addition, Guangxi mainly uses cassava starch as the main raw material, and its output will reach 15% of the domestic output.
From the demand side, due to the continuous economic growth, the continuous expansion of industrial production scale, and the improvement of the production and R & D technology of the modified starch industry, the consumption demand of modified starch is on the rise as a whole. The product demand is mainly oxidized starch, compound modified starch, cationic starch and acetate starch.
In the future, the preparation of denatured starch will mainly develop into a high-efficiency, pollution-free and green synthetic process. Driven by both economic and social benefits, modified starch will develop more rapidly in the next few years.
