How do Salt and Sugar Preserve Food?
If a red blood cell is placed in pure water, it will swell and eventually explode. This is due to a process called osmosis, which is also critical to the internal operation of many organisms. The red blood cell has a makeup that causes it to absorb water. When placed in water with a salt concentration equal to that of the blood, the red blood cell experiences no osmosis, and stays a constant size. When placed in highly salty water, the environment around the red blood cell will start sucking out the fluids inside the cell through osmosis, causing it to shrivel and die. This is the phenomenon of osmotic pressure. Food is spoilt when certain microorganisms begin to reproduce on and digest its surface, releasing harmful toxins as byproducts of their metabolic processes. Sometimes the microorganisms themselves — mostly bacteria and fungus — present a risk to humans, as ingesting them is an invitation to reproduce within the host’s body. Therefore, to preserve food, one must ensure that it
