Monosodium glutamate (MSG) is a commonly used flavor enhancer in the food industry. It works by enhancing the natural flavors of foods, making them more savory and appealing to the palate. MSG is a sodium salt of glutamic acid, an amino acid found naturally in many foods. When added to dishes, it interacts with the taste receptors on our tongues, intensifying the perception of umami, a savory taste. Despite some controversy surrounding its potential health effects, MSG is generally recognized as safe by regulatory authorities when consumed in moderate amounts and is valued for its ability to elevate the overall taste and enjoyment of various culinary creations.
