How yeasts effects food?

Yeasts play a crucial role in food production, primarily through fermentation. They convert sugars into alcohol and carbon dioxide, which is essential in the making of bread, beer, and wine. This fermentation process not only enhances flavor and texture but also contributes to the preservation of food by lowering pH and creating an environment less conducive to spoilage. Additionally, certain yeasts can produce beneficial compounds, such as vitamins and enzymes, that can enhance the nutritional value of food.
