The slide of the vegetable drawer in the refrigerator is not just a simple cover; It regulates the air flow and humidity inside. As humidity-controlled storage systems develop, freshness management is moved to separate compartments in smart refrigerators.
Leafy vegetables continue to lose water after harvest. High humidity in the drawer slows this loss and helps keep the cells taut; Thus, products such as lettuce and spinach wilt later.
For fruit, lower humidity and more air flow are generally more suitable. If the ethylene gas released by apples, pears and similar products accumulates in a closed area, it can accelerate the ripening of the surrounding products.
When the slider is closed, air output is reduced and moisture is trapped inside. In the open position, it becomes easier for moisture and gases to escape. Since overfilling the drawer may disrupt air circulation, it is necessary to leave a small amount of space between products.
Leafy vegetables require high humidity, fruits require low humidity.
As a rule of thumb, leafy vegetables can be stored in a high humidity indoor setting, and most fruits can be stored in a low humidity outdoor setting. For sensitive products such as strawberries and mushrooms, packaging and washing time also change the result.
If drops of condensation form, it is necessary to ventilate the drawer for a short time, separate the rotting parts and place the products dry. To summarize, the right humidity setting can prolong freshness; But temperature, air circulation and product separation are equally important.
