Placing cork stoppers inside the fridge has become a popular homemade trick to try to reduce bad odors. The method, which has been circulating for several years, is based on the idea that cork could help absorb smells and some moisture. However, the Economic and Food Safety Authority (ASAE) does not recommend this practice and states that it found no evidence that one or two stoppers are sufficient to solve a persistent bad odor problem.
ASAE instead recommends simple cleaning and maintenance care. The fridge should be kept at a temperature between 3°C and 4°C, which hinders the multiplication of microorganisms. The entity recommends regularly cleaning the interior, removing spoiled foods, and immediately cleaning any spills. These measures help not only to combat unpleasant odors but also to reduce food safety-related risks.
As for how food is stored, ASAE recommends placing it in suitable containers or properly protected, avoiding raw foods coming into contact with already cooked foods. Foods with strong odors should be stored in closed containers to prevent the smell from spreading. The appliance should also not be overfilled, allowing cold air to circulate between the products.
The Portuguese Cork Association (APCOR) describes cork as a material practically impermeable to liquids and gases and resistant to moisture, due to substances such as suberin. This means that cork should not be viewed as a sponge intended to absorb moisture. If the fridge has an unpleasant smell, the priority should be to identify the source, such as a spoiled food, spilled liquid, or poorly closed packaging. Although there is no problem with reusing stoppers in this way, the trick should not be used to mask a problem or replace the care recommended by ASAE.
