In 2014, potato production in China amounted to 96 million tons, which was the highest in the world. As one of the most important nutritional foods in the world, potato is rich in starch, dietary fiber, vitamins, minerals, etc. Potatoes stand barren environment, drought, saline, and alkaline environment, and cold weather, with a short growing season. These features make them the best rain-fed crops suitable for production even when the annual rainfall is below 400 mm. In 2013, the Chinese Ministry of Agriculture suggested a potato staple food strategy using potatoes to make Chinese traditional staple foods such as steamed bread, noodles, etc. Our research group carried out a study on processing technology of potato staple food, especially fermented staple food. Some new processing technologies of potato staple food have been investigated and developed. The aim of this paper is to give an overview of the possible effects of adding potato flour in the dough and of the microstructure characteristics, technological parameters, total polyphenol content, and antioxidant activity of staple foods. We also systematically describe the processing technology of potato staple foods, which may be of great importance in promoting further expansion of the potato-processing industry and increasing the economic benefit of the companies.
