A person cannot taste food unless it is mixed with saliva. For example, if strong-tasting substance like salt is placed on a dry tongue, the taste buds will not be able to taste it. As soon as a drop of saliva is added and the salt is dissolved, however, a definite taste sensation results. This is true for all foods. Try it!
