Tidecom Potato Starch Processing Terminology Sharing

September 13 , 2022

Potatoes are the fourth most important food crop in the world, after wheat, rice and maize. After more than 20 years of development, China's potato starch processing industry has formed a number of industrial zones. However, the naming of potato starch processing sections by various manufacturers and suppliers is relatively random, and no unified naming rules have been formed. In order to further Standardize the terms and definitions of each section. As a professional company dedicated to the development and manufacture of complete sets of machinery and equipment for food and agricultural products processing, Tidecom Technology Co., Ltd. has gradually formed its own set of product standardization terms and definitions based on years of work experience. We hope to further accelerate the development of industry standardization.
