Is the bread sealed at room temperature or open

It is recommended to seal bread at room temperature for short-term storage, and freeze seal it for long-term storage. The storage method of bread is mainly related to factors such as humidity control, microbial growth rate, and starch aging degree.

Sealed storage of bread at room temperature can effectively delay moisture loss, prevent surface dryness and hardness, and is suitable for consumption within 2-3 days. A sealed environment can reduce the attachment of fungal spores, but it should be noted that condensation inside the packaging may accelerate local mold growth. When using food grade sealed bags or freshness boxes, it is recommended to let the bread cool completely first to avoid the accumulation of water vapor. If water droplets are found on the inner wall of the packaging, the drying container should be replaced in a timely manner.

Open storage of bread is suitable for situations where freshly baked bread needs to dissipate heat or maintain a crispy texture, but exposure to air can accelerate starch retrogradation, leading to a harder texture. When the environmental humidity exceeds 60%, open storage is prone to mold growth, especially during the rainy season or in humid kitchen environments where the risk is higher. If you want to keep the bread crust crispy, you can wrap it in a breathable cotton cloth first and then place it in a cool and ventilated place, but it is recommended to consume it within 8 hours. Regardless of the storage method chosen, it is recommended to cut the bread into edible portions and package them separately to avoid repeated opening and accelerated spoilage. Whole wheat and mixed grain bread are easier to dry and harden than white bread due to their lower oil content, and can be wrapped with an additional layer of aluminum foil to block air. If mold spots or a sour taste are found on the bread, it should be discarded immediately. The aflatoxin produced by mold cannot be decomposed even when cooked at high temperatures. Uneaten bread can be frozen and stored in daily life. Before consumption, it can be reheated in the oven to restore its soft texture. Frozen storage can maintain the same flavor for up to one month.
