Beyond Food: Fermentation
Fermentation isn't limited to culinary applications. It's pivotal in biofuel production, pharmaceuticals, and even waste management. Yeast fermentation helps create ethanol, a renewable fuel, showcasing the process's versatility.
The Science Behind Flavors
The Science Behind Flavors
The distinct flavors in fermented products stem from esters, ketones, and alcohols formed during the metabolic activities of microbes. These compounds are responsible for the complex flavor profiles in cheese, yogurt, and more.
