Abstract

The invention provides a gluten-free protein biscuit manufactured by sweet potato coarse dietary fibers and a preparation method of the gluten-free protein biscuit. Raw materials for manufacturing the gluten-free protein biscuit include sweet potato coarse dietary fiber starchy flour, sweet potato coarse dietary fiber superfine powder, sweet potato coarse dietary fiber nano-powder, sweet potato modified starch, extrusion sweet potato coarse dietary fiber powder, sweet potato coarse dietary fiber microwave treatment powder, sweet potato starch, food gum, plant source polyphenol, albumen, sugar, salt, baking soda, ammonium bicarbonate, edible oil, water and the like. The weight ratio of the raw materials is 10-40: 10-40: 10-20: 4-12: 5-12: 5-13: 0.5-6: 0.1-3: 0.1-0.7: 1-3: 0.5-25: 0.1-3: 0.1-1: 0.1-0.5: 14-34: 20-69. The sweet potato coarse dietary fiber gluten-free protein biscuit manufactured by the method has unique flavor of a sweet potato, is crisp in taste, golden in color and rich in protein, coarse fibers, vitamin, mineral elements and the like, and has fine nutrition and health care functions.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a gluten-free biscuit made from sweet potato crude dietary fiber and a preparation method thereof. Background technique [0002] Biscuits are loose or crunchy foods made from wheat flour as the main raw material, added with sugar, oil and other raw materials, and processed by powder mixing, molding, baking and other processes. Because biscuits have the advantages of storage resistance, crispy taste, and convenient eating, they are deeply loved by the masses. Traditional biscuits are mostly made of wheat flour. In the processing of wheat flour, many nutrients are lost due to excessive pursuit of processing precision. In addition, the lysine content in wheat flour protein is low, which also affects the nutritional value of biscuits. With the formation of the concept of healthy diet consumption and the advent of various health foods, traditional biscuits have also begun to develop i...
