Toast has become a part of family breakfast, especially for people with children at home. They feel that they often buy toast bread outside and worry that preservatives and additives in it will have an impact on their children's growth and development, so they want to make their own bread. Medium gluten flour can be used to make bread, because the protein of this wheat flour is not high and the color is purple. Many snacks and toast are made of this medium-gluten flour.
