Method for producing sweet potato residue biscuits

Abstract

The invention relates to a method for producing sweet potato residue biscuits. The method comprises the following steps of rinsing sweet potato residues with water, filtering and draining with a strainer, and dissolving and mixing oil, eggs and white sugar in a water bath; adding low-gluten flour and wet or dry potato residues, after fully mixing, kneading into a dough, and pressing into a wrapper with a thickness of 2-4mm by a dough pressing machine; and processing the wrapper into a shape meeting the requirement by using a biscuit die, baking and cooking to obtain sweet potato residue biscuits. The wet or dry sweet potato residues with high content of dietary fiber are used as a raw material, and the total dietary fiber and soluble dietary fiber content of the produced biscuits is high; on the basis of keeping the color, smell and taste of original biscuits, vitamins, niacin, folic acid and other nutrients are added; the biscuit can be used as a diet food and a food for regulating blood sugar, blood pressure and serum cholesterol; the sweet potato residues have better adaptability to flour, and the forming effect is good; the biscuit does not contain toxic, hazardous and carcinogenic matters and is safe to eat; the process is simple, the continuity is good, the operation cost is low, and the utilization rate is high; and in the production process, the produced waste is less, and the environment is not polluted.

Description

technical field [0001] The invention relates to a method for making sweet potato dregs biscuits. Background technique [0002] At present, besides fresh food, 45% of sweet potatoes are used as raw materials for food processing, and most of them are used for processing starch and starch products. Sweet potato dregs are by-products in the production process of sweet potato starch and starch products. Usually It is discarded as waste or simply utilized as feed, resulting in waste of resources and environmental pollution, so it is necessary to solve the problem of comprehensive utilization of sweet potato residue. [0003] In addition to more starch, sweet potato dregs are also rich in dietary fiber. Some people use fermentation to remove impurities, alkalinize hydrolysis, decolorize, extrude and dry, and extrude the dried crude fiber with a twin-screw extruder. , crushing, and other processes to obtain dietary fiber. Sweet potato residue is rich in pectin, the sweet potato re...

[0004] The existing method of making sweet potato dregs biscuits is to use a single-screw extruder to extrude and expand the raw material of sweet potato dregs, dry and crush them for use, but the taste of sweet potato dregs produced by this method is relatively hard and not loose
