Bread unpredictable since the steam is not produced until the bread is baked. Steam leavening happens regardless of the raising agents (baking soda, yeast, baking powder, sour dough, beaten egg white) included in the mix. The leavening agent either contains air bubbles or generates carbon dioxide. The heat vaporises the water from the inner surface of the bubbles within the dough. The steam expands and makes the bread rise. This is the main factor in the rising of bread once it has been put in the oven. CO generation, on its own, is too small to account for the rise. Heat
Rye bread either batter-type or dough-type (similar to Irish soda bread). In such cases, it can be used in similar applications as whole wheat flour, since an egg matrix often provides the bread structure rather than the grain's gluten. Rye bread contains a large amount of fiber and a small amount of fat. Compared to some breads such as white bread, rye bread has a lower glycemic index, which means it causes a slower increase in blood sugar than white bread after being eaten. Nonetheless, it consists mostly of carbohydrates, making its glycemic load high. Rye bread Rye bread is a type
