Annāda is one of the sons of the Agni (Fire )called Arka. According to the conception of Upaniṣad (Upanishad), Agni is the bhoktā (bhokta; consumer) of anna (edibles) or all kinds of āhutidravya (ahutidravya; things offered to fire). So he is also known as Annāda. It seems that this name of Agni is attributed to the son of the Agni called Arka.
