Even in the cleanest of kitchens, there can be an intrusive odor that spoils the taste of food. The problem isn’t always a forgotten piece of cheese or expired milk. Often the source of the stench is hidden in the technical features of household appliances or biological processes that occur on a microscopic level.
Biological activity of bacteria and molds
The main cause is the viability of microorganisms. Cold only slows down their reproduction, but does not stop it completely.
-
Mold can take up residence in porous rubber seals of the door where condensation and crumb residue accumulate.
-
Bacteria are active in drainage holewhich is designed to drain moisture. If it becomes clogged with food particles, water stagnates there, providing an ideal environment for decay.
-
Fresh fruits and vegetables release ethylene and moisture, which accelerates spoilage of neighboring products in closed crates.
Technical factors and operational disturbances
Sometimes an odor signals that the refrigerator is not working properly or needs maintenance.
-
Clogged drainage system causes water to accumulate under the bottom drawers.
-
On models with the system No Frost odors can circulate throughout the entire chamber through the ventilation duct system. If one product has spoiled, its “aroma” will be absorbed into the plastic walls and other open dishes.
-
New plastic or insulation elements may emit a specific chemical odorwhich should eventually wear off.
-
The temperature inside the chamber is too high due to a loose fit magnetic seal provokes rapid bacterial growth.
Features of food storage
The materials from which the refrigerator is made have the ability to absorb volatile molecules.
-
Polymers (plastic) easily absorb strong odors from fish, garlic or spices. If such products are stored without airtight containers, it will be difficult to get rid of the plume even after washing.
-
Open containers of liquids contribute to the increase of humiditywhich indirectly leads to the formation of slime on the shelves.
-
Drugs stored on the door can react with food vapors, creating a specific pharmacy background.
To maintain freshness, it is important to regularly check the drain hole for cleanliness and the condition of the rubber gaskets. The use of special odor absorbers based on activated charcoal or ordinary baking soda helps minimize the problem, but does not eliminate its root cause. Timely revision of the shelves and compliance with the rules of product neighborliness allow you to keep a neutral aroma inside the unit for many years.
