In our country, cassava has long been used as a non-food energy crop to produce starch, alcohol and feed. In recent years, the development of breeding, popularization and deep-processing technology of the edible cassava have greatly expanded the development space of cassava in the food industry. Firstly, the varieties and nutritional value of the edibble cassava are introduced in this article, and then the present research and application situation of the edibble cassava in food industry field are summarized, from three aspects: Fresh edibble cassava, edible cassava whole flour and starch, and modified starch. On this basis, the developmental advantage and the problems of the edible cassava are analyzed, the development prospect of the edible cassava in food industry are forecasted, such as variety breeding, storage and preservation technologies, processing technologies and product development, in order to offer some references for our country's edible cassava industrial in the future.
