These vegetables should not be stored in the refrigerator
The A&L network published a report based on recommendations from food safety experts and specialized nutritionists, who confirm that storing certain types of vegetables in the refrigerator not only fails to extend their shelf life, but actually causes their taste, texture, and nutritional value to deteriorate faster than if they were left at room temperature. The report clarified that the common belief that everything must be refrigerated is a widespread misconception that costs consumers the quality of their fresh produce.
The report stated that experts identified three main types of vegetables that should be kept outside the refrigerator, with tomatoes (plums) being the primary example. They explained that refrigeration halts the activity of enzymes responsible for flavor development, turning their texture into something akin to flour—a process that cannot be reversed even after returning the fruit to room temperature. Furthermore, experts noted that low temperatures break down the cellular membranes inside the tomato, resulting in an undesirable mushy texture.
The list also included potatoes. The report explained that refrigeration accelerates the conversion of starches into sugars, causing potatoes to develop an undesirable sweet taste when cooked. Additionally, they become unattractively dark in color after frying or roasting. Experts warned that this chemical transformation of starches can also lead to the formation of acrylamide, a chemical compound of health concern, in higher amounts when potatoes stored in the refrigerator are cooked at high temperatures.
The report also conveyed specialists’ insistence that onions are the third variety that should be stored outside the refrigerator, for the following reasons:
• The high humidity inside the refrigerator accelerates the rotting of onions, turning them into a soft mass, as they easily absorb moisture from their surroundings.
• Refrigeration softens their texture and causes them to lose their characteristic crispness, making them less suitable for uses that require clean cutting and a firm texture.
• The pungent odors of onions can transfer to other sensitive products in the refrigerator, such as dairy and eggs, negatively affecting their taste.
The report emphasized that the optimal rule for storing these vegetables is to keep them in a cool, dry, and dark place, such as a kitchen cabinet or a well-ventilated basket, away from direct sunlight and heat sources. It stressed the importance of separating onions from potatoes, as the gases emitted by each accelerate the spoilage of the other. The source noted that following these simple guidelines can extend the shelf life of these products by several additional weeks, while preserving their quality and original taste as if they were freshly harvested.
