Glutamic Acid and the Vegan Diet
Glutamic acid, often referred to as L-glutamic acid or E620, is a non-essential amino acid that plays a crucial role in protein synthesis and is commonly used in food as a flavor enhancer. It is naturally present in a variety of foods, including meats, dairy products, and some vegetables. In the food industry, it is often used to enhance flavors, particularly the umami taste, which is one of the five basic tastes.
