The correct answer is option 1: oxidation. When food items are fried in oil, the oil undergoes a chemical reaction called oxidation. This process occurs when the oil is exposed to air and heat, causing it to break down and become rancid.

Oxidation is a natural process that happens to all oils over time. During oxidation, the fat molecules in the oil react with oxygen in the air, leading to the formation of free radicals and the breakdown of the oil`s chemical structure. This results in the development of an unpleasant taste, odor, and a change in the appearance of the oil.

To prevent consuming rancid oil, it is essential to check the date of manufacture of food items fried in oil before buying them. By checking the manufacturing date, you ensure that you are purchasing fresh food items that have not been sitting in the oil for an extended period. Consuming rancid oil can not only affect the taste and quality of the food but may also have negative health effects due to the production of harmful compounds during oxidation.
