According to China Starch Industry Association (CSIA), China's total output of starches (corn starch, cassava starch, potato starch, sweet potato starch, wheat starch, etc.) reached 19.7 million tonnes in 2010, increasing by 9.7% over 2009. Moreover, the output of corn starch, the largest category of starch in China, also increased by about 10% in 2010 over last year. Meanwhile, sweet potato starch, wheat starch and other starches also witnessed slight increase in output, and that of potato starch rose obviously. But CSIA didn't reveal the accurate output data of cassava starch in 2010. (FIGURE2)
