The water content material of foods and resources, called the drinking water action, can be lowered without having Actual physical drying because of the addition of solutes for example salts or sugars. At extremely significant concentrations of salts or sugars, the level of available h2o in microbial cells is reduced radically due to the fact drinking water are going to be drawn from a place of reduced solute focus (In the cell) to an area of superior solute focus (outside the house the cell) (Determine (PageIndex seven )). Many microorganisms do not endure these problems of large osmotic force.
