Problems solved by technology

Although the bread improver prepared by the prior art has a certain effect on increasing the volume of bread, improving the firmness of bread and improving the fineness of bread tissue, the prepared bread will still lose its luster, lose its aroma, and lose its luster during storage. Reduced moisture, hardened slag and other phenomena will reduce the quality of bread and shorten the shelf life

Abstract

The invention discloses a flour improver and application thereof in bread making. The flour improver comprises the components in percentage by weight of 70-73% of soybean isolate protein culture, 20-25% of wheat bran culture and the balance of konjak powder. The additive amount of the improver in the bread making is 1-2% of the weight of flour. The dough added with the improver in bread making has high tenacity and good air holding capacity and is fermentation-resistant, the well kneaded dough has dry hand feeling and large elasticity, and the machining performance of the dough is improved; the dough is largely expanded after entering an oven and is high in stiffness and fine in tissue, a made bread has large size, good flavor and soft mouth feeling, and the softness of the bread is obviously improved.

Description

technical field [0001] The invention relates to a flour improver, in particular to a flour improver containing active bacillus and edible fungi, belonging to the field of flour product additives. Background technique [0002] Bread is a nutritious convenience food. During its processing, it has high requirements on the quality of flour. Generally, high-gluten flour is used as raw material to make it. The essence is the requirement on the quality of wheat gluten. The quality of wheat gluten has a great influence on the quality of flour products, and scientific researchers at home and abroad try to improve the quality of gluten through various methods. These methods include wheat breeding, adjustment of wheat processing technology, and addition of appropriate food additives. Adding appropriate food additives is a relatively simple and efficient method, but it also introduces some food safety problems. Potassium bromate was considered to be the best gluten-strengthening agent ...
