Yes, both Accent and Ajinomoto are brand names for the food additive monosodium glutamate (MSG), which is used as a savor enhancer in cooking. Both products essentially provide the same function — they amplify the savory, umami flavor in dishes. The major contrast between the brand name and possibly the country of manufacture. Ajinomoto is a Japanese company that was the original commercial producer of MSG, while Accent is a brand name commonly seen in the United States.
