Industrial starch is also a kind of starch, but there is no standard for its purity. This starch can't be used to eat it, but can only be used for a specific purpose in industry. For example, industrial starch is now used in many places in some industrial fields. If there is no such catalyst as industrial starch, many reactions cannot be carried out in the industrial process. Therefore, industrial starch has such a market space and a great market prospect.
