Caution is advised when reusing cooking oil multiple times.
It's generally recommended to limit the reuse of cooking oil to a maximum of 2-3 times for frying, depending on the type of food cooked, to minimize health risks.
Reusing cooking oil can be a common practice in many kitchens but comes with risks. When oil is heated, it undergoes chemical changes, which can produce harmful compounds and free radicals. The more times oil is used, the more these harmful substances can build up. Signs that oil is no longer safe to use include a rancid smell, excessive thickness, or dark coloration. To safely reuse cooking oil, it is important to strain it through a fine mesh or cheesecloth after cooling. Store the strained oil in a dark, cool place and keep track of how many times it has been used. It's generally recommended to limit the reuse of cooking oil to a maximum of 2-3 times for frying, depending on the type of food cooked, to minimize health risks.
