Can potatoes be cut and stored in the refrigerator

After cutting potatoes, they can be stored in the refrigerator, but attention should be paid to the storage method and time. Cut potatoes are prone to oxidation, blackening, or bacterial growth. It is recommended to soak them in clean water or store them in a sealed refrigerator.

Soak the cut potatoes completely in clean water and refrigerate them in a fresh-keeping layer below 4 degrees Celsius to slow down oxidation and extend the shelf life to about 1 day. Clear water should completely cover the surface of potatoes to avoid contact with air. A small amount of white vinegar or lemon juice can be added to water to inhibit enzymatic browning, but soaking for more than 6 hours may result in the loss of some water-soluble vitamins. refrigerated potatoes are recommended for cooking methods that require thorough heating, such as stewing. If sealed in a box or wrapped in plastic wrap and refrigerated, un soaked potato chunks may experience edge browning within 2-3 hours. Although it does not affect food safety, the taste may deteriorate. When sealing and storing, pay attention to wiping off surface moisture to avoid accelerated decay caused by condensed water. Potatoes that have sprouted or turned green on the surface are not recommended for consumption even if they are cut into pieces and refrigerated, as their high content of solanine may cause poisoning. Potatoes are rich in starch and vitamin C. After refrigeration, the starch is partially converted into resistant starch, resulting in a decrease in glycemic index but a harder texture. It is recommended to choose the storage method according to cooking needs. The shredded potatoes for cold mixing should be cut and used immediately, while the potato chunks for stewing can be refrigerated and prepared in advance. Regardless of the storage method, it is necessary to observe for signs of spoilage such as mucus and odor before reuse to ensure food safety.
