Corn starch, also known as corn starch, also known as corn flour. Commonly known as Liugu powder. A yellowish white powder. It is made by soaking corn with 0.3% sulfurous acid, crushing, sieving, precipitating, drying and grinding. Ordinary products contain a small amount of fat and protein.

Strong hygroscopicity, up to more than 30%.

The main varieties of starch sugar in China are maltose syrup, high maltose syrup and glucose, accounting for more than 80% of starch sugar.

Starch sugar can be divided into solid and liquid according to its physical state. In 2006, the output of solid starch sugar was 2.45 million tons, including 6.5438+0.4 million tons of glucose, 450,000 tons of maltose essence and 3.65438+0.5 million tons of liquid starch sugar, including 2.6 million tons of maltose syrup and 400,000 tons of fructose syrup. From the whole development situation, the development of solid starch sugar is higher than that of liquid starch sugar.

From 20065438+0 to 2005, the price of starch sugar fluctuated little. Calculated by crystalline glucose, the price of starch sugar is basically around 2 100-2300 yuan/ton. In the second half of 2005, with the growth of corn raw materials, the price of starch sugar rose slightly, fluctuating between 2700-3000 yuan/ton.
