Many households experience confusion and domestic disagreements over proper food storage, with a significant portion of the public uncertain about whether certain items belong in the refrigerator or the cupboard.
A survey indicated that three-quarters of people are so perplexed by food storage guidelines that it results in arguments at home. Specialist dietitian Nichola Ludlam-Raine and food waste expert Kate Hall provide clarity on these common dilemmas.
Refrigeration Guidelines
Eggs: While refrigerators often have built-in egg compartments, Ludlam-Raine advises keeping eggs in their original carton on a shelf, rather than in the door, as the temperature in the door fluctuates more. Storing them this way can also prevent cracking when boiling.
Butter: Modern butters often contain added ingredients like rapeseed oil and water to make them spreadable straight from the refrigerator. While pure butter, especially salted, might be kept in a cool larder in less heated homes, Ludlam-Raine generally recommends refrigeration for most butter.
Bread and Cake: Chilling bread accelerates staling by firming up the starches, even though it may slow mold growth. It is best stored in a bread bin at room temperature. Cakes, with their high sugar content, are best kept in an airtight container in a cool, dark place.
Fruit: Most fruits ripen better at room temperature. Bananas should always be stored separately at room temperature as they emit ethylene gas, which can accelerate the ripening and spoilage of other fruits. Apples can be kept in a bowl but will last longer in the refrigerator, though they should be removed if any start to spoil. Avocados should be ripened on the counter before refrigeration.
Vegetables: Potatoes and onions are incompatible storage partners. Onions release ethylene gas that causes potatoes to sprout and rot, while potatoes emit moisture that makes onions soft and moldy. While historically advised against due to concerns about "cold sweetening," current understanding suggests refrigeration can extend the shelf life of potatoes. Onions and garlic are best kept in a pantry until cut. Leafy greens should always be refrigerated to maintain nutrients. Ludlam-Raine advises against washing and storing produce before use; keeping it in its original packaging is recommended.
Tomatoes and Salad: Tomatoes taste better and ripen more effectively at room temperature, provided they are kept out of direct sunlight. Lettuce and cucumber, however, should remain chilled and in their original protective packaging.
Jams, Spreads, and Honey: Nut butters can be stored in a cool, dark cupboard. Honey should be kept at room temperature to prevent crystallization. While older generations may have stored jams and marmalades in cupboards, Ludlam-Raine recommends refrigeration after opening to prevent spoilage, as the vacuum seal is broken. Hall emphasizes using a clean utensil to avoid contamination and never attempting to salvage moldy products.
Chocolate: Refrigeration can cause "sugar bloom" in chocolate, where sugar crystallizes on the surface, affecting its texture and taste. It is best stored in a cool, dry place, or in an airtight container during hot weather.
Olive Oil: To maintain quality, olive oil should be stored away from light and heat, making a cupboard the ideal location. It should not be refrigerated.
Ketchup and Mustard: Manufacturers like Heinz recommend refrigerating ketchup after opening due to its acidity and sugar content. While Hall suggests that ketchup's high sugar and vinegar content makes cupboard storage relatively low-risk if used quickly, refrigeration is advised during heatwaves. Opened mustard should always be refrigerated.
