Should You Be Frying with Used Cooking Oil?

Many wonder if they should cook with used cooking oil when they fry foods. Used cooking oil is used by many people, but they disregard the health influences of using used cooking oil. The oil itself is pretty durable when it comes to heat. The problem is that the food that was cooked with the used cooking oil can be a problem depending on how long it has been sitting in the old cooking oil.

Most cooking oils have a long expiration date, but you have to remember that cooking oils do have a lifespan. Near the end of their lifespan they become rancid. That is when the bulk cooking oil has decomposed. The decomposition of the bulk oil is not as bad as the decomposition of the food fragments in the used cooking oil. When food begins to decay you usually see obvious signs when it is out in the open. When food decays in used oil it is almost impossible to spot it. In most cases, people won't die when they fry foods in used cooking oil because of the extreme temperatures that the cooking oil reaches. Heat doesn't make it healthy cooking oil again, but in many cases it makes it usable for cooking. That is because there are many types of organisms and other pathogens that can survive in extreme temperatures.
