I would say yes, but not in the same way that we taste our food. As far as I know, snakes do not have taste buds in their mouths like us, so they don't actually taste the food item as they're swallowing it. But they use their tongues and a specialized organ (the Jacobson's organ) to sample the air and pick up clues to their surroundings. (That's why snakes are flicking their tongues all the time.) As the tongue waves around, it picks up particles from the nearby air. Those particles are then taken in and sent to the Jacobson organ for analysis. Whether the process is a form of taste, smell, or both, or some other sensing process that we humans do not possess, I am unsure. But it is this method by which snakes can sense potential prey nearby (or predators, potential mates, etc. ) . So, in a way, they can taste it before they actually eat it!
Others on this forum may be able to elaborate more on this process, or correct me if I have it wrong.
