In biological materials numerous transformations can be observed as a function of environmental conditions and humidity plays an important role during these processes. Chemical reactions such as Maillard reactions and spontaneous oxidations are directly related to the extent of hydration. Similarly, the initiation and intensity of such phenomena as the growth of microorganisms, photosynthesis, seed germination and, as a general consideration, enzyme activity are dependent on the humidity of the medium. |
