Yeast is one of the oldest components of our cooking and drinking. The peculiar microorganisms that stood at the origins of baking and winemaking have long become an integral part of our culture and economy. The yeast, thanks to their enzymes, promote fermentation and raise bread, taste beer and wine, and enrich some products with lactic acid. But what are the usefulness and harm of yeast, and how did they become our faithful companions for centuries?
Yeast History: The history of yeast dates back to millennia. The first mention of the use of yeast in cooking and winemaking belong to ancient civilizations, such as Mesopotamia and Ancient Egypt. Yeast gave strength in the preparation of bread and alcoholic beverages, their use was widespread among different crops.
Since ancient times, yeast has been received from natural sources such as fruits and berries. However, the greatest impact on the production of yeast was the discovery of Louis Pasteur in the 19th century. He found out that yeast is a living microorganisms and that they play a key role in fermentation and fermentation processes.
The usefulness of yeast:
Bakery: yeast play an important role in baking, turning the dough into air and soft bread. They spread the sugar inside the dough, releasing carbon dioxide, which gives bread volume and porosity.
Alcohol production: yeast is used for fermentation of juice or wort in alcoholic beverages. They turn sugar into alcohol and carbon dioxide. It is a process that underlies the production of wine, beer, whiskey and other drinks.
Dairy products: yeast can be used for fermentation of milk, creating products such as yogurt and yogurt. Fermentation promotes the enrichment of lactic acid, which makes them useful for digestion.
Biologically active additives: yeast also contains many important vitamins and trace elements such as B vitamins, iron, zinc and others. Adding them to food can improve the enrichment of the body with useful elements.
Damage and problems:
Individual intolerance: Some people may experience an allergic reaction to yeast. This can be manifested in the form of itching, rash or other symptoms.
Excessive alcohol consumption: alcohol production with yeast can lead to excess alcohol, which can cause health problems.
Obesity: bread and other yeast products can contain many calories and carbohydrates, which can contribute to weight gain and obesity.
Yeast - important microorganisms that affect many aspects of our lives, starting with bread and ending with alcohol production. Their history is rich and reaches a long time. Yeast benefits, enriching our food and drinks, but as with any product, they should be consumed with moderation. By observing the quantity and quality of yeast in our diet, we can enjoy their beneficial properties, minimizing the possible health risks.
