Factors affecting starch yield
Sweet potato varieties and origins: Sweet potatoes with red skin and white heart have higher starch content, while sweet potatoes produced in hilly areas have higher starch content.
Extraction process: The traditional precipitation and drying extraction process is prone to incomplete crushing and inadequate purification due to its simple equipment. However, professional sweet potato crushing equipment uses enlarged rollers and rotary knives for powerful crushing, combined with two-stage screening. Elutriation can extract starch more effectively.
Sweet potato flour content: The flour content of sweet potatoes is generally between 20% and 28%. The specific value will vary depending on the sweet potato variety and place of origin.
