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. Industrially then mainly produce sweet potato slices, but because by deep-frying, internal nutritional labeling has been destroyed, thus has been far away from this subject function of sweet potato health-care effect; Reports on cutting sweet potatoes into slices, drying them, grinding them and even extracting sweet potato starch to process sweet potato rice noodles (CN201410032939.6, CN201610195939.7, CN201310696115.4, CN201410575904.7)

The preparation of sweet potato regeneration rice also has report (CN200710035944.2, CN201310621813.8, CN201410032939.6, CN201210399841.5, CN201110342121.0, CN201410107500.5, CN201310474778.1), but all use sweet potato to carry out powder preparation and On the one hand, there is no sweet potato taste in the mouthfeel, which is not liked by people. On the other hand, sweet potatoes contain about 70% moisture. Sweet potato flour has poor adhesion, and the regenerated rice made directly with broken rice has poor shape and poor chewiness, making it difficult to make uniform and stable regenerated rice products, and the taste is rough
