Who discovered to add yeast to bread to make rise ,and was brave enough to eat it?

Answer 1

Yeast are simple, unicellular fungi. The most common forms of yeast -- baker's and brewer's yeast -- are strains of the species Saccaromyces cerevisiae. Yeast is often taken as a vitamin supplement because it is 50 percent protein and is a rich source of B vitamins, niacin, and folic acid.

Yeast microbes are probably one of the earliest domesticated organisms. People have used yeast for fermentation and baking throughout history. Archaeologists digging in Egyptian ruins found early grinding stones and baking chambers for yeasted bread, as well as drawings of 4,000-year-old bakeries and breweries. Only in the last 150 years, since the experiments of Louis Pasteur, have scientist begun to explore how yeast works. Pasteur first proposed the production of carbon dioxide from yeast as responsible for raising a loaf of bread in 1859.

Answer 2

I don't think yeast was purposefully added to bread to make it rise. It was one of those things that happened and when they (the cavemen?) cooked it, it was good. Just like beer or alcohol fermentation and even making cheese/yougurt.

In fact, if you let flour and water mixture sit in a warm place it will naturally bubble up from the natural yeast in the flour. That's how a lot of wild yeast (sourdough) starters are created.

Since yeast is everywhere, a lot of people think you need to expose the flour-water mixture to air near a window or using grapes, but the reality is the yeast is already in the packaged flour.

Answer 3

This is an ancient fact.

It’s likely that man used yeast before the development of a written language. Hieroglyphics suggest that that ancient Egyptians were using yeast and the process of fermentation to produce alcoholic beverages and to leaven bread over 5,000 years ago. The biochemical process of fermentation that is responsible for these actions was not understood and undoubtedly looked upon by early man as a mysterious and even magical phenomenon.

Answer 4

You have to knead the dough for 8-10 minutes in order for it to be light. Test the water by putting your baby finger in it. If it feels nice and warm, it's good. Try not to add flour when kneading, just sprinkle some on your work area. You should be fine next time. Make sure the dough rises in a warm room. Yeast loves being warm.

Answer 5

Leaven, a type of yeast, is spoken of in the Old Testament of the Bible, so knowledge of yeasts goes back thousands of years and the one who discovered it use will never be known. It is quite possible that God gave the knowledge of the use of yeast to Eve, we cannot know this for sure but God mentions bread in the book of Genesis.

Answer 7

Well, I guess when man first appeared he wasn't thinking, "I wonder if this is safe to eat..."
He was probably eating whatever he could get his hands on.
