Good bacteria thus prevent spoilage of foods. However, similar processes take place in the leavening of bread (CO2 produced by yeast activity), and in the preservation of sour foods with the production of lactic acid, such as in sauerkraut and yogurt. Fermentation is the process of converting carbohydrates to alcohol or to organic acids using microorganisms, such as yeasts or bacteria. When studying the fermentation of sugar to alcohol by yeast, Pasteur concluded that the fermentation was catalyzed by a vital force, called "ferments", within the yeast cells. Incorrect temperatures, fermentation times, or unsterile equipment can cause the food to spoil, making it unsafe to eat. Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic conditions. [8] The two fermentations most commonly used by humans to produce commercial foods are ethanol fermentation (used in beer and bread) and lactic acid fermentation (used to flavor and preserve dairy and vegetables). These chemical changes are brought about by various chemicals called enzymes. organic acids, gases or alcohol).
