The yeast of the genus Zygosaccharomyces have had a long history as spoilage yeasts within the food industry. This is mainly because these species can grow in the presence of high sucrose, ethanol, acetic acid , sorbic acid , benzoic acid , and sulfur dioxide concentrations, [ 74 ] representing some of the commonly used food preservation methods.
The introduction of commercial yeasts during the 19th century was detrimental to sourdough as these speeded up the baking process making production much easier. [ 37 ] Common additives include reducing agents such as L-cysteine or sodium metabisulfite , and oxidants such as potassium bromate or ascorbic acid ; [ 38 ] [ 39 ] this last ingredient ...
Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker 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 ...
Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period (around 10 000 years BC) [1] fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities (in this case, taste, sight, smell, touch).
Baker's yeast has the advantage of producing uniform, quick, and reliable results, because it is obtained from a pure culture. [50] Many artisan bakers produce their own yeast with a growth culture. If kept in the right conditions, it provides leavening for many years. [51] The baker's yeast and sourdough methods follow the same pattern. Water ...

Charles Louis Fleischmann (November 3, 1835 – December 10, 1897) was a Jewish Hungarian-American manufacturer of yeast who founded Fleischmann Yeast Company.. In the late 1860s, he and his brother Maximilian created America’s first commercially produced yeast, which revolutionized baking in a way that made today's mass production and consumption of bread possible.
