Although bread is a staple in most households, its longevity and quality can be affected by how it is stored. Many people believe that keeping bread in the fridge prolongs its shelf life.
However, this is not the case. Doing so can lead to faster bread spoilage and reduced flavor and texture.
Understanding the science of staling will allow you to understand why keeping bread in the fridge can affect its quality and longevity.
This process involves the retrogeny of starch molecules. When the starch is absorbed by water, it forms a gelatinous and soft texture when fresh bread is made.
The starch molecules then recrystalize once the bread cools. This process then produces a firm and dry texture once it has been exposed to temperatures of 32 to 50 degrees Fahrenheit.
The starch recrystalizes faster when stored in the fridge compared to when it is kept at room temperature.
This accelerates the staling process, and it also negatively affects the flavor and texture of bread.
The moisture collected by the starch molecules cannot evaporate and settles on the surface of bread, making it look unappealing and dry.
In addition, the cold process can also cause bread to absorb the flavor of other food items inside the fridge. This could result in bread tasting off-flavor and stale.
Some people believe that holding bread in the fridge will help prevent mold growth by lowering the temperature.
However, this theory is not true since the staling process is accelerated by this process. In order to prevent mold, keeping bread in a dry airtight container is ideal.
Freezing bread is a better option when it comes to preserving its freshness.
This method effectively stops both staling and mold development, allowing the bread to remain fresh. It should be stored in a cool, dry area such as a paper bag or bread box.
This ensures that the bread maintains its moisture balance. For long storage, it can be sliced and placed in a plastic bag prior to freezing.
The texture and taste of the bread can be preserved by either thawing or toasting it. It is customary to keep bread in the fridge to prolong its shelf life.
Studies reveal that the speed at which starch retrogradation occurs in the presence of refrigeration accelerates the staling process, resulting in reduced flavor and texture.
By comprehending the impact of this phenomenon, we can make better decisions regarding the preservation of bread. One way to achieve this is by freezing or keeping it at room temperature.
