This invention discloses the formation of a new molecule when one mole only of D-ribose crystalline powder is mixed with one mole only of water at room temperature which new substance is entirely different from the precursor molecule, and a monohydrate of D-ribose is the likely newly discovered molecule formed with both the precursor and the result able to form caramels at below 100.degree. C. so can form relatively low temperature caramel taste when mixed with other sugars.
