Remember that when the concept of nutritious diet began to be accepted by the public in the early 1990s, everyone knew that the food is diverse, and most of the food on the table is a single ingredient, such as a bun, a piece of corn, a piece of sweet potato, a bowl of porridge …. The addition of coarse grains has significantly increased dietary fiber and other nutrients in food, improving the health of many people.

　　 And now we are not only rich in food, but also pursuing high quality of life and paying more attention to fashion and nutrition. Therefore, smart cooks always have constant innovations. They can make purple potatoes with unfermentable flour and plain flour together to make beautiful purple potato rolls! The difference between purple potato and wheat flour is that they contain Rich anthocyanin, dietary fiber, selenium and other nutrients can complement the nutrition of refined flour. Not only does it taste soft, but it also unconsciously achieves a balanced diet.

　　Potatoes are not genetically modified crops. They are also potato foods. Compared with sweet potatoes and sweet potatoes, the anthocyanin content is significantly higher. Purple potatoes have the same carbohydrate content as rice, and can be replaced in a 1:1 ratio if consumed as a staple food. Anthocyanins are good antioxidants, which can help to eliminate free radicals, anti-oxidation and anti-aging in the body.

　　 There is a key problem for making purple potato rolls, because most of the main staple foods are fermented with yeast, and some chefs like to use some baking powder at the same time, and the result will be a strange phenomenon- —Purple red, snow and white purple sweet potato flowers roll into blue-grey blue and white flower rolls. The baking soda in the mystery root baking powder is alkaline, while the anthocyanin appears blue-gray in a slightly alkaline environment, but bright in a slightly acidic environment. Only purple yeast rolls need to be put in yeast That''s it.
