Problems solved by technology

[0003] But for a long time, people have traditionally eaten sweet potatoes in a single way. The home eating methods of fresh sweet potatoes are mainly raw food, boiled food, roasted food or boiled and sun-dried sweet potatoes, but these are basically ready-to-eat products and are not easy to store for a long time. ; Industry is mainly to produce sweet potato slices, but due to frying, the internal nutritional labeling has been destroyed, thus away from the theme function of sweet potato health care; Grinding or even extracting sweet potato starch to process sweet potato noodles (03135115.8, 201310258266.1, 201410519420.6, 20141038.722.X), but because the main component of the sweet potato powder is starch, the processed noodles are heated due to the effect of sugar in the starch It turns gray-black, and at the same time, there is no taste of sweet potato in the taste, which is not liked by people

In addition, sweet potato contains about 70% water. During the processing of flour, it not only causes a large loss of water and soluble components such as vitamin B and vitamin C, but also has poor adhesion of sweet potato flour. It is difficult to form noodles directly with flour. It is easy to disperse, not only difficult to make uniform and stable noodle products, but also rough in taste
