23 Meals You Ought to By no means Refrigerate (and Why It Issues)

Most of us assume the fridge is the most secure place for meals. However for a surprisingly lengthy checklist of on a regular basis elements, the fridge is definitely the worst place you may put them. Chilly temperatures destroy taste compounds, halt ripening, convert starches to sugar, promote mould, and make textures mushy, all whereas convincing you the meals is being preserved.

What meals must you by no means refrigerate?

The brief reply: Tomatoes, potatoes, onions, garlic, honey, espresso, olive oil, bread, unripe avocados, bananas, entire melons, contemporary basil, chocolate, and apples (for peak taste) ought to by no means be refrigerated. These meals are actively broken by chilly temperatures in methods that can not be undone. The fridge makes them style worse, lose dietary worth, or deteriorate sooner than pantry storage would.

For a whole reference on which meals DO want refrigeration and the way lengthy they final, see our Food Storage Guide.

Why Refrigerating the Fallacious Meals Makes Them Worse

Fridges maintain meals secure by slowing bacterial progress, however chilly air additionally halts enzymatic exercise, disrupts cell membranes, causes condensation, converts starches to sugars, and absorbs odors. For meals developed to ripen at room temperature or saved in dry pantry circumstances, these results are dangerous relatively than useful.

🔬 The Science in One Sentence
Many vegetation and fruits include enzymes and unstable fragrant compounds that solely develop correctly between 50 and 70 levels Fahrenheit. Beneath that vary, enzyme exercise halts, taste compounds cease creating, and cell partitions can rupture from ice crystal formation. All of that are irreversible as soon as they happen.

20 Meals You Ought to By no means Refrigerate

1. Tomatoes

Tomatoes are essentially the most generally cited instance of fridge injury, and the science is evident. Chilly temperatures under 55 levels Fahrenheit break down the unstable fragrant compounds that give tomatoes their taste. Additionally they halt the enzymatic ripening course of and injury the cell partitions, leading to a mealy, watery, flavorless texture that can not be reversed by bringing the tomato again to room temperature.

⚠️ What the Analysis Exhibits
Analysis printed within the Proceedings of the Nationwide Academy of Sciences (Zhang et al., 2016) confirmed that tomatoes saved under 55 levels Fahrenheit misplaced important quantities of their key taste compounds inside days. The chilling silenced genes answerable for producing taste volatiles, and a few of these genes didn’t recuperate their exercise even after tomatoes had been returned to room temperature, making the flavour loss at the least partially everlasting.

Retailer as a substitute: On the counter, stem facet down, at room temperature.
