Plain toast containing galactooligosaccharide, and production method thereof

Abstract

The invention relates to a plain toast added containing galactooligosaccharide, and a production method thereof. Raw materials of the plain toast comprise second-stage fermented dough, warm fermenteddough and first-stage fermented dough, the second-stage fermented dough is mainly made of special high-gluten flour for bread, and the plain toast is made from, by mass, 20-40% of the warm fermented dough and 80-120% of the double-fermented dough on the basis of the special high gluten flour for bread of the second-stage fermented dough. The production method of the plain toast combines a secondary fermentation method and a warm fermentation method, and adopts a secondary fermentation mode, and raw materials are subjected to stirring, dough forming, loosening, shaping, primary fermentation, exhausting, shaping, secondary fermentation, die filling, baking, cooling and the like. The fermentation time is shortened, meanwhile, the roast is soft and elastic; and the galactooligosaccharide is used, so the sweetness and the calorie are low, the intestinal microenvironment is improved, absorption of various trace elements in the wheat germ flour is promoted, the moisture retention can be improved, and the shelf life is prolonged.

Description

technical field

[0001] The invention relates to a plain toast bread added with galacto-oligosaccharide and a preparation method thereof, belonging to the technical field of food processing. Background technique

[0002] Galactooligosaccharide is a natural functional oligosaccharide formed by linking 1-4 galactose molecules at one end of galactose through the action of β-galactosidase. Galacto-oligosaccharides exist in human and animal milk and can proliferate beneficial bifidobacteria in the intestines, so they are widely used in infant milk powder. In addition, galacto-oligosaccharides can also improve lipid metabolism in the body, lower cholesterol; promote intestinal absorption of minerals; cannot be used by microorganisms in the oral cavity, no damage to teeth; and are not easily absorbed by the intestinal tract, low energy , is a healthy sweetener that special patients can eat. Galacto-oligosaccharides, as the only oligosaccharides that can be utilized by eight kinds ...
