What is yeast?!
Answers: NOT Yeast Infection but yeast to make bread?
Yeast are organisms like bacteria. Some species can metabolize pentose sugars, alcohols, and organic acids. This process is called fermentation.
Yeast is used in baking as a leavening agent, where it converts the fermentable sugars present in the dough into carbon dioxide. This causes the dough to expand or rise as the carbon dioxide forms pockets or bubbles. When the dough is baked it "sets" and the pockets remain, giving the baked product a soft and spongy texture.
Alcoholic beverages are loosely defined as a beverage that contains ethanol. This ethanol is almost always produced by fermentation - the metabolism of carbohydrates by certain species of yeast. Beverages such as wine, beer, or distilled spirits all use yeast at some stage of their production.
It's what makes the bread rise.
yeast is a small mircoorganism. They're classified as fungi, but they're not really like musrooms in any meaningful way to anyone but a biologist.
In the yeast from a packet each little granuole is actually throusands of yeast cells, you would need a microscope to see the individual yeast. You can also buy liquid yeast, or brick yeast if you want to be different.
Yeast makes bread rise because the yeast eat the sugar, and give off carbon dioxide (a gas) as a waste product. That's why you have to use a whole bunch of sugar in bread, but it doesn't usually come out tasing very sweet.
Yeast also help impart flavor into the bread. If you bake bread with brewer's yeast instead of bread yeast you'll notice a different taste, although not as profound as if you brew beer with bread yeast.
it's a bacteria, same as the infection. only this type of bacteria is useful to us; it is exposed to heat in the oven and it expands, making the bread rise. people usually freak out when they hear they're eating a bacteria, but yogurt is also a bacteria. activia is one that advertises it as a bacterial cutlures. not all bacteria is bad for us!
yeast is a living organism. If u leave a grain of yeast and don't touch the table u will see the piece of yeast jump in the air......
its pretty cool
