Why did Jianmin starch factory stop?

Preservatives are put in the starch. Hebei Jianmin Starch Sugar Co., Ltd. was registered in Ningjin County Administration for Industry and Commerce on July 24th, 2002. In 20 13, because the starch contained preservatives, it was sealed up by the relevant departments, and the production license was revoked, so the production was stopped. Starch is a kind of high molecular carbohydrate, which is a polysaccharide polymerized by glucose molecules.
