What would happen if spacesuit helmet was removed for 10 seconds on the moon?

Despite all unlikelihood, consider this hypothetical situation: An astronaut stands on the moon. He currently has no access to any form of shelter --aside from his space suit. He is on the brink of starvation. If he can stay alive a little longer he will be rescued, but he must eat to do so. He has food rations in hand. Assuming he must unseal/unfasten his helmet to ingest the food, could he do so and survive?
If no one is certain how long it might take an astronaut to make such a maneuver, let us hazard a guess that the whole process would take no longer than 10 seconds.
What would be the affects of depressurization and the subsequent exposure to the vacuum of space within this 10 second time frame.
Also, would the space suit return to its previous functioning state afterward?
