Abstract

The invention provides a potato steamed bread. The steamed bread is prepared from the following components in parts by weight: 10-40 parts of potato pulp cornflour, 10-40 parts of potato slag superfine powder, 10-20 parts of potato slag nano powder, 4-12 parts of potato modified starch, 5-12 parts of extruded potato slag powder, 5-13 parts of potato slag microwave processing powder, 0.5-6 parts of potato starch, 0.1-3 parts of food gum, 1-3 parts of protein, 0-1 part of sugar, 0-3 parts of salt, 1-2 parts of yeast and water, wherein the weight ratio of water to other components is (50-70) to 100. The defects existing in common wheat steamed bread are overcome; the potato steamed bread does not contain gluten so as to be suitable for being eaten by people who are allergic to wheat and barley or patients with celiac diseases, is comprehensive in nutritional ingredients, and has a health function.

Description

technical field [0001] The invention relates to the field of food, in particular to a gluten-free, nutritious and comprehensive steamed bun with potato dregs as the main raw material and a production method thereof. Background technique [0002] Traditional steamed buns are generally made with wheat flour as the main raw material, and gliadin and glutenin are necessary for the fermentation of steamed buns, which can form a unique network structure of gluten to obtain dough with good strength, elasticity and gas holding capacity. [0003] At present, processing by-products from different sources are added to steamed bread to improve the nutritional value of steamed bread products, such as peanut residue, bean curd residue, tomato residue, kiwifruit residue, and sweet pepper residue, etc. These residues are rich in dietary fiber. The addition amount in steamed bread is about 1-12%. However, there are few studies on potato crude dietary fiber, and there are even fewer studies o...
