◆Process introduction

Starch is a multicolor-based natural polymer compound. It is an important food for mankind and has a wide range of uses in industrial production. Due to the development of industry, the natural properties of starch can no longer meet the requirements. In the past ten years, people have used chemical, physical chemistry or enzyme catalysis technology to process starch. Hundreds of modified starches have been developed to meet the requirements of industrial production. The main raw material crops for starch production are sweet potatoes and corn. Starch wastewater is a high-concentration acidic organic wastewater, and various comprehensive water quality indicators greatly exceed the requirements of environmental protection standards, which will cause a large degree of pollution to the environment.
