Leavening agent in the context of "Polysaccharides"

The Eucharist (/ˈjuːkərɪst/ YOO-kər-ist; from Koine Greek: εὐχαριστία, romanized: eucharistía, lit. 'thanksgiving'), also called Holy Communion, the Blessed Sacrament or the Lord's Supper, is a Christian rite, considered a sacrament in most churches and an ordinance in others. Christians believe that the rite was instituted by Jesus Christ at the Last Supper, the night before his crucifixion, giving his disciples bread and wine. Passages in the New Testament state that he commanded them to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the blood of my covenant, which is poured out for many". According to the synoptic Gospels, this was at a Passover meal.

The elements of the Eucharist, sacramental bread—either leavened or unleavened—and sacramental wine (among Catholics, Anglicans, Lutherans, Eastern Orthodox and Oriental Orthodox) or non-alcoholic grape juice (among Methodists, Baptists and Plymouth Brethren), are consecrated on an altar or a communion table and consumed thereafter. The consecrated elements are the end product of the Eucharistic Prayer.

Unleavened bread is any of a wide variety of breads which are prepared without using raising agents such as yeast or sodium bicarbonate. The preparation of bread-like non-leavened cooked grain foods appeared in prehistoric times.

Unleavened breads are generally flat breads. Unleavened breads, such as the tortilla and roti, are staple foods in Central America and South Asia, respectively. Unleavened sacramental bread plays a major part in Christian liturgy and Eucharistic theology.

Bread is a baked food product made from water, flour, and often yeast. It is a staple food across the world, particularly in Europe and the Middle East. Throughout recorded history and around the world, it has been an important part of many cultures' diets. It is one of the oldest human-made foods, having been of significance since the dawn of agriculture, and plays an essential role in both religious rituals and secular culture.

Bread may be leavened by naturally occurring microbes (e.g. sourdough), chemicals (e.g. baking soda), industrially produced yeast, or high-pressure aeration, which creates the gas bubbles that fluff up bread. Bread may also be unleavened. In many countries, mass-produced bread often contains additives to improve flavor, texture, color, shelf life, nutrition, and ease of production.

Ammonium carbonate is a chemical compound with the chemical formula [NH₄]₂CO₃. It is an ammonium salt of carbonic acid. It is composed of ammonium cations [NH₄] and carbonate anions CO2−3. Since ammonium carbonate readily degrades to gaseous ammonia and carbon dioxide upon heating, it is used as a leavening agent and also as smelling salt. It is also known as baker's ammonia and is a predecessor to the more modern leavening agents baking soda and baking powder. It is a component of what was formerly known as sal volatile and salt of hartshorn, and produces a pungent smell when baked. It comes in the form of a white powder or block, with a molar mass of 96.09 g/mol and a density of 1.50 g/cm. It is a strong electrolyte.

Batter is a flour mixture with liquid and other ingredients such as sugar, salt, egg, milk and leavening used for cooking. Batters are a pourable consistency that cannot be kneaded. Batter is most often used for cake, pancakes and as a coating for fried foods. It is also used for a variety of batter breads.

The word batter comes from the French word battre, which means to beat, as many batters require vigorous beating or whisking in their preparation.

Baker's yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ethanol. Baker's yeast is of the species Saccharomyces cerevisiae, and is the same species (but a different strain) as the kind commonly used in alcoholic fermentation, which is called brewer's yeast or the deactivated form nutritional yeast. Baker's yeast is also a single-cell microorganism found on and around the human body.

The use of steamed or boiled potatoes, water from potato boiling, or sugar in a bread dough provides food for the growth of yeasts; however, too much sugar will dehydrate them. Yeast growth is inhibited by both salt and sugar, but more so by salt than sugar. Some sources say fats, such as butter and eggs, slow down yeast growth; others say the effect of fat on dough remains unclear, presenting evidence that small amounts of fat are beneficial for baked bread volume.

Roti is a round flatbread originating from the Indian subcontinent. It is commonly consumed in many South Asian, Southeast Asian, Caribbean, East African, and Southeast African countries.

It is made from stoneground whole-wheat flour, known as atta, combined into a dough with added water. Its defining characteristic is that it is unleavened. Naan from the Indian subcontinent, by contrast, is a yeast-leavened bread, as is kulcha. Like breads around the world, roti is a staple accompaniment to other foods.
