Bread is often stored by many families in the refrigerator to limit mold and prolong the duration of use, especially on hot and humid weather days. However, many people worry that low temperatures can cause nutrients in this food to be lost. In fact, cold storage does not significantly reduce bread's nutritional value, but it can affect the softness, freshness and flavor of the bread.
According to Ms. Archana, Head of Nutrition at KIMS Mahadevapura Hospital (India), the main nutritional components in bread such as carbohydrates, protein, fiber, vitamins and minerals are almost always preserved when stored in the refrigerator. In other words, cooling does not cause bread to lose significant nutritional value.
However, the most obvious change is the texture of bread. When stored at low temperatures, the process of starch degradation occurs faster. This is the phenomenon of starch molecules rearranging their structure after the bread is cooled, making bread drier, harder and less soft than when fresh. Therefore, although nutritional value is almost unchanged, eating experience can be significantly affected.
In addition to structural changes, the cooling process also creates a notable nutritional change. A portion of the starch in bread can be converted into resistant starch when stored at low temperatures for a certain period of time. This type of starch is more difficult to digest and acts similarly to fiber in the body. As a result, it can support bowel movements and bring some benefits to the digestive system.
However, if the goal is to keep bread fresh for a long time, freezing is often considered a more effective choice than keeping it in the refrigerator. Freezing helps slow down processes that make the bread dry and hard, while prolonging the shelf life while still maintaining better flavor and texture when properly thawed.
According to recommendations, storing bread in the refrigerated compartment is mainly suitable in extremely hot weather or high humidity conditions, when the risk of mold develops quickly. In these cases, cooling can help limit food spoilage. However, if you intend to use bread for many days, freezing is still the preferred option.
Experts also note that the quality of the chosen bread is considered more important than whether it is refrigerated or not. Whole wheat bread, cereal bread or bread rich in fiber often have higher nutritional value than refined bread.
Storing bread in the refrigerator does not significantly lose nutrients. The main changes are the softness, freshness and flavor of the bread. To both extend the shelf life and maintain the best quality, freezing is often a more suitable choice than storing it in the refrigerator.
