All food will break down overtime as micro organisms go to work. At normal room temperature, the bacteria thrive, and depending on the food, they will multiply quickly to dangerous levels. By freezing the food, the micro organisms don't die, but they will multiply at much slower rates, meaning the food will keep longer.

∙ 11y agoThe main way in which a freezer (or any means of refrigeration) preserves foods is by slowing down the growth of bacteria, which then dramatically reduces the rate at which the food spoils. It works because bacteria multiplies at a significantly lower rate as temperatures drop.
