Sour Dough
Sourdough is a type of bread that uses the fermentation by naturally occurring yeast and lactobacillus bacteria to raise the dough. In addition to leavening the bread, the fermentation process produces lactic acid, which gives the bread its distinctive sour taste and improves its keeping-qualities. History Sourdough is one of the most ancient forms of bread. It was the standard method of breadmaking for most of human history until the Middle Ages, when it was replaced by barm. Barm, in turn, was replaced in the late 19th and early 20th centuries by industrially produced baker's yeast. The ''Encyclopedia of Food Microbiology'' states: "One of the oldest sourdough breads dates from 3700 BCE and was excavated in Switzerland, but the origin of sourdough fermentation likely relates to the origin of agriculture in the Fertile Crescent and Egypt several thousand years earlier", and "Bread production relied on the use of sourdough as a leavening agent for most of human history; the use ...

Bread
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#History, agriculture, and plays an essential role in both religious rituals and secular culture. Bread may be Leavening agent, leavened by naturally occurring microbes (e.g. sourdough), chemicals (e.g. baking soda), industrially produced Baker's yeast, yeast, or high-pressure aeration, which creates the gas bubbles that fluff up bread. Bread may also be Unleavened bread, unleavened. In many countries, mass-produced bread often contains Food additive, additives to improve flavor, texture, color, shelf life, nutrition, and ease of production. Etymology The Old English language, Old English word for bread was ( in Gothic langua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Gold Rush
The California gold rush (1848–1855) began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to grow rapidly into statehood in the Compromise of 1850. The gold rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation, and the California genocide. The effects of the gold rush were substantial. Whole indigenous societies were attacked and pushed off their lands by the gold-seekers, nicknamed "forty-niners" (referring to 1849, the peak year for gold rush immigration). Outside of California, the first to arrive were from Oregon, the Sandwich Islands (Hawaii), and Latin America in late 1848. Of the approx ...

Coeliac Disease
Coeliac disease (British English) or celiac disease (American English) is a long-term autoimmune disorder, primarily affecting the small intestine. Patients develop intolerance to gluten, which is present in foods such as wheat, rye, spelt and barley. Classic symptoms include gastrointestinal problems such as chronic diarrhoea, abdominal distention, malabsorption, loss of appetite, and among children failure to grow normally. Non-classic symptoms are more common, especially in people older than two years. There may be mild or absent gastrointestinal symptoms, a wide number of symptoms involving any part of the body, or no obvious symptoms. Due to the frequency of these symptoms, coeliac disease is often considered a systemic disease, rather than a gastrointestinal condition. Coeliac disease was first described as a disease which initially presents during childhood; however, it may develop at any age. It is associated with other autoimmune diseases, such as Type 1 d ...

Louis Pasteur
Louis Pasteur (, ; 27 December 1822 – 28 September 1895) was a French chemist, pharmacist, and microbiologist renowned for his discoveries of the principles of vaccination, Fermentation, microbial fermentation, and pasteurization, the last of which was named after him. His research in chemistry led to remarkable breakthroughs in the understanding of the causes and preventions of diseases, which laid down the foundations of hygiene, public health and much of modern medicine. Pasteur's works are credited with saving millions of lives through the developments of vaccines for rabies vaccine, rabies and anthrax vaccine, anthrax. He is regarded as one of the founders of modern bacteriology and has been honored as the "father of bacteriology" and the "father of microbiology" (together with Robert Koch; the latter epithet also attributed to Antonie van Leeuwenhoek). Pasteur was responsible for disproving the doctrine of spontaneous generation. Under the auspices of the French Aca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germ Theory Of Disease
The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or "germs" can cause disease. These small organisms, which are too small to be seen without magnification, invade animals, plants, and even bacteria. Their growth and reproduction within their hosts can cause disease. "Germ" refers not just to bacteria but to any type of microorganism, such as protists or fungi, or other pathogens, including parasites, viruses, prions, or viroids. Diseases caused by pathogens are called infectious diseases. Even when a pathogen is the principal cause of a disease, environmental and hereditary factors often influence the severity of the disease, and whether a potential host individual becomes infected when exposed to the pathogen. Pathogens are disease-causing agents that can pass from one individual to another, across multiple domains of life. Basic forms of germ theory were proposed by Girolamo Fracastoro ...

Yukon Territory
Yukon () is a territory of Canada, bordering British Columbia to the south, the Northwest Territories to the east, the Beaufort Sea to the north, and the U.S. state of Alaska to the west. It is Canada’s westernmost territory and the smallest territory by land area. As of the 2021 census, Yukon is the middle territory in terms of population, but the most densely populated. Yukon has an estimated population of 47,126 as of 2025. Whitehorse, the territorial capital, is the largest settlement. Yukon was split from the Northwest Territories by a federal statute in 1898 as the Yukon Territory. The current governing legislation is a new statute passed by the federal Parliament in 2002, the ''Yukon Act''. That act established Yukon as the territory's official name, although Yukon Territory remains in popular usage. Canada Post uses the territory's internationally approved postal abbreviation of YT. In 2021, territorial government policy was changed so that The Yukon would be rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Department Of Alaska
The Department of Alaska was the designation for the government of Alaska from its purchase by the United States of America in 1867 until its organization as the District of Alaska in 1884. During the department era, Alaska was variously under the jurisdiction of the U.S. Army (until 1877), the U.S. Dept. of the Treasury (from 1877 until 1879), and the U.S. Navy (from 1879 until 1884). The area later became the District of Alaska, then the Territory of Alaska, then the State of Alaska. History At the instigation of U.S. Secretary of State William Seward, the United States Senate approved the purchase of Alaska from the Russian Empire for $7,200,000 on April 9, 1867, and the United States flag was raised on October 18 of that same year (now called Alaska Day). Coincident with the ownership change, the de facto International Date Line was moved westward, and Alaska changed from the Julian calendar to the Gregorian calendar.

Fructilactobacillus Sanfranciscensis
''Fructilactobacillus sanfranciscensis'' is a heterofermentative species of lactic acid bacteria which, through the production mainly of lactic and acetic acids, helps give sourdough bread its characteristic taste. It is named after San Francisco, where sourdough was found to contain the variety, though it is dominant in Type I sourdoughs globally. In fact, ''F. sanfranciscensis'' has been used in sourdough breads for thousands of years, and is used in 3 million tons of sourdough goods yearly. For commercial use, specific strains of ''F. sanfranciscensis'' are grown on defined media, freeze-dried, and shipped to bakeries worldwide. Overview ''Fructilactobacillus sanfranciscensis'' was first known to be isolated in 1971 by Kline and Sugihara. As lactic acid bacteria, the strains are Gram-positive, slender, rod-shaped, nonsporulating, and non-motile. They are also obligately heterofermentative, meaning that they can convert hexose sugars into not just lactic acid, but also et ...
