CCTV's Weekly Quality Report reporter visited many gelatin factories and medicinal capsule factories in Hebei, Jiangxi, Zhejiang and other places, and found that two gelatin production enterprises, Yang Xue Gelatin Protein Factory in Hebei and Guifeng Gelatin Company in Yiyang, Jiangxi, produced industrial gelatin with "blue alum skin" with excessive chromium as raw material, and then put it in white bags without any product identification, and sold it to Xinchang, Zhejiang through some secret sales chains.

Because of its relatively low price, this kind of industrial gelatin was bought by the local capsule factory as a raw material for the production and processing of medicinal capsules. This medicinal capsule with chromium exceeding the standard flows into Qinghai Gradandong, Jilin Changchun Overseas Pharmaceutical and other pharmaceutical factories to make various capsule medicines.

Public network-the producer of problem capsules can't get away with it.
