Sweet potatoes have larger planting areas in all parts of the country, especially in Shenqiu County, Henan Province, where the scope of sweet potato cultivation is even greater. The annual output is very considerable, and because it contains a large number of polysaccharides and mucous proteins required by the human body, it can improve the human body. Immunity, prevention of arteriosclerosis, treatment of diabetes, etc. are deeply loved by people. However, people often take sweet potatoes directly to the market for selling, which is inconvenient for transportation and low prices. If the sweet potato is processed into food for sale, its added value can be greatly increased and better economic benefits can be obtained.

Take 70%—100% of sweet potato white starch as the main material, put the good raw material into the autoclave and cook for 35 minutes to fully gelatinize the starch, so as to increase the bonding force between the blanks, and quickly cool it below 0° C. to make it Sticky hands can be cut into pieces. The billet is cut to a thickness of less than two millimeters. The sheet is further monotonously adjusted at 50° C. for at least 6 hours. The moisture content of the billet is about 10%, and the billet is fried at 190° C. for 20 seconds, and the resulting cake becomes bulky, crispy and sweet. The finished product.
Five, sweet potato hair cake
Take 5 kg of sweet potato flour and 760 grams of flour, 750 grams of sugar, 19 grams of soda and appropriate amount of warm boiling water.
