The word acid is derived from the Latin word acere which means “sour.” Acid itself is a corrosive metal. However, in foods when mixed with various bases, its harmful effects are diminished even eliminated and leave only a sour flavor. To test to see if a food compound contains acids, a piece of litmus paper is used by dipping the litmus into compounds. If the litmus paper then turns red, the compound contains acids.
