Problems solved by technology

Sweet potato dregs, a by-product of sweet potato starch processing, are often used in the production of sweet potato biscuits. Sweet potato dregs are rich in dietary fiber, accounting for about 10% to 14% of raw materials. However, simply adding sweet potato dregs as raw materials to biscuits , so that the content percentage of sweet potato dietary fiber in biscuits is relatively low. Usually, sweet potato dietary fiber can be extracted from sweet potato dregs and added to biscuits. However, the extraction rate and purity of sweet potato dietary fiber extracted from sweet potato dregs are usually low, which affects the sweet potato in sweet potato biscuits. Dietary fiber content, thus reducing the health function of biscuits

Abstract

The invention discloses a health-care sweet potato dietary fiber biscuit and a preparation method of the health-care sweet potato dietary fiber biscuit, and refers to the field of food processing. The health-care sweet potato dietary fiber biscuit is mainly used for solving the problems of low extraction rate and purity of sweet potato dietary fiber and low health-care performance of the biscuit. The health-care sweet potato dietary fiber biscuit comprises the following raw materials in part by weight: 40-60 parts of sweet potato leaves, 30-50 parts of sweet potato slag, 30-50 parts of wheat powder, 5-10 parts of black sesame powder, 3-9 parts of radix ophiopogonis, 5-11 parts of astragalus membranaceus, 4-12 parts of ligusticum wallichii, 4-10 parts of red-rooted salvia, 3-9 parts of schisandra chinensis, 4-9 parts of wolfberry fruit, 3-9 parts of agaric, 3-8 parts of almond, 3-8 parts of semen coicis, 1-5 parts of olive oil, and 1-5 parts of corn oil. The health-care sweet potato dietary fiber biscuit is rich in nutrition components, and suitable for people of all ages; after long-term use, the biscuit has health-care function.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a health-care sweet potato dietary fiber biscuit and a preparation method thereof. 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] Adding the sweet potato dietary fiber into the biscuit can increase the dietary fiber content of the biscuit and increase the health care performance of the biscuit. Sweet potato dregs, a by-product of sweet potato starch processing, are often used...
