Abstract

The invention discloses a sweet potato dietary fiber pastry and a preparation method thereof and relates to the field of food processing. The sweet potato dietary fiber pastry mainly solves the problem of low content of dietary fiber in existing pastries. The sweet potato dietary fiber pastry comprises, by mass, 40-60 parts of sweet potato leaves, 30-50 parts of sweet potato residue, 30-50 parts of glutinous rice flour, 5-10 parts of dogbane leaf, 3-9 parts of gastrodia elata, 5-11 parts of corn stigma, 4-12 parts of lily, 4-10 parts of water chestnut, 3-9 parts of white fungus, 4-9 parts of yam, 3-9 parts of hawthorn, 3-8 parts of shepherd's purse, 3-8 parts of black garlic, 1-5 parts of sesame oil and 1-5 parts of olive oil. The sweet potato dietary fiber pastry is rich in nutrition, sweet in taste and suitable for people of all ages and has a health care effect when used for a long term.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of sweet potato dietary fiber cake. Background technique [0002] Sweet potato dietary fiber plays an important role in maintaining a healthy digestive system, and adequate fiber intake can also prevent cardiovascular disease, cancer, diabetes, and other diseases. Sweet potato dietary fiber is divided into two categories: soluble dietary fiber and insoluble dietary fiber according to solubility. The part of dietary fiber that comes out; insoluble dietary fiber refers to the part of dietary fiber that is not hydrolyzed by human digestive tract enzymes and is insoluble in hot water. [0003] The by-product of sweet potato starch processing, potato dregs, is rich in dietary fiber, accounting for about 10% to 14% of the raw material. Sweet potato dregs are often used in the production of cakes. However, simply adding sweet potato dregs as raw materials Make sweet...
