A. Angina (angina pectoris-Latin for squeezing of the chest) is chest discomfort that occurs when there is a decreased blood oxygen supply to an area of the heart muscle. In most cases, the lack of blood supply is due to a narrowing of the coronary arteries as a result of arteriosclerosis.Angina may be felt as:.

Leavened bread is bread that contains leavening, usually yeast. Leavened bread is soft, light, and fluffy in texture. It contains tiny air pockets, making it somewhat resemble a sponge. The leavening which was mixed into the bread dough causes the dough to rise both before it is baked and during baking.Examples are most kinds of bread you would buy in a grocery or bakery-French bread, Italian bread, sandwich breads and rolls, muffins, etc.east, baking powder, and a combination of baking soda â¦ and vinegar or lemon juice, are the typical leavening agents used in baking. Leavened bread is bread that incorporates any, some, or all of the above agents.
Leavening gases are responsible for the volume in most baked food products; to leaven means to make light; to raise. They are responsible for expanding the air bubbles that have been mixed, creamed, kneaded or whipped into the batter or dough. Leaveners also contribute to baked goods' taste, coloring and texture. THE FOUR BASIC LEAVENING GASES: The basic leavening gases commonly found in baking recipes are: air; water vapor or steam; carbon dioxide; and biological. In baking recipes, one or more leavening agents participate in the leavening process. However, chemical leaveners and yeast usually are not combined, but there are some recipe exceptions. In some frozen or refrigerated dough found in the grocery store, yeast and chemical leavenings complement each other.
