To help solve the transportation difficulties, potato is made into whole flour by many food processing companies. Potato whole flour has high nutritional value and may be regarded as beneficial to human health and fitness. In addition to the direct use of potato whole flour,it can also be used as added ingredients into other food products. This study summarizes and analyzes the processing technology of potato whole flour and its application in noodle products.展开更多
