Problems solved by technology

[0002] Chestnut is rich in nutrients and contains a lot of nutrients such as starch, protein, fat and B vitamins. It is known as the "king of dried fruits". It is native to my country. In my country, chestnut resources are abundant and the annual output is high. However, fresh chestnut It is easy to deteriorate and not easy to preserve. Therefore, the waste of chestnut resources caused by the deterioration of chestnuts every year is huge
[0003] Although chestnut is nutritious, it has certain defects in the process of eating: first, although chestnut contains 8 kinds of essential amino acids for human body, its total content is less, which is only similar to the content in flour; second, the cellulose in chestnut The content of chestnuts is also lower than that of other grains, which cannot meet the requirements of the human body for dietary fiber intake; third, raw chestnuts are not easy to digest, while cooked food is easy to stagnate.
[0004] In the prior art, in addition to steaming, boiling, frying, and cooking of chestnuts, the processing methods of chestnuts also have some deep processing, such as making instant batter with chestnut powder, making milk tea powder with chestnut powder, or mixing chestnut powder with other ingredients. Plant powder or food additives are mixed to make puffed food, such as Chinese patent CN1460431A, which discloses a chestnut food and its processing technology. Food additives such as sweeteners are added to the chestnut food. These food additives will bring health problems to the human body ; Another example is Chinese patent CN101099583A, which discloses a processing method of chestnut puffed products, which only adds cassava flour in chestnut powder, which is insufficient for nutritional supplements such as vitamins and cellulose. At the same time, swirl puffing can introduce heavy metal impurities in food , there are food safety issues
