Product Information

You can prevent discoloration by covering peeled and cut slices with an inch or two of water and refrigerating them until you’re ready to use them ( 1). It’s okay to freeze them once they are fully or partially cooked, as the cooking process deactivates the browning enzymes and prevents them from discoloring ( 15). Summary Resistant starch also promotes gut health, since gut bacteria ferment it and produce short chain fatty acids, which help keep the lining of your large intestine healthy and strong ( 25, 26, 27). Sunlight or fluorescent light can cause potato skins to produce chlorophyll and turn an undesirable green color ( 1). This is because the enzymes that cause browning are still active in the potato, even under freezing temperatures ( 14).

Not sure how to use your well-preserved potatoes? Never fear! You can freeze potatoes, or cook them up whenever the mood takes you. You’ve never really got too many potatoes, only limitless options for your next meal. Need some inspiration for how to use your spuds? Here are our top seven ways to use up leftover potatoes. However, many countries have mandatory guidelines that limit the amount of solanine in commercial potatoes to under 91 mg per pound (200 mg/kg), so this is not a common concern ( 8, 9). First things first, you need to separate your potatoes so you know what you can use in the short and long term. If you spy any bruising or broken skin, use them up sooner and leave the unscathed potatoes for later on. Be sure not to wash your spuds before storing, the exposure to moisture invites rotting and greening to spread and will ultimately shorten the storage life. Where should I store them? Storing at temperatures slightly above refrigeration is a great way to extend shelf life and maintain vitamin C content. Summary Firm to the touch: Soft potatoes have already begun to degrade, so look for firm, bright qualities.

Where should I store potatoes?

Solanine creates a bitter taste and causes a burning sensation in the mouths or throats of people who are sensitive to it ( 6). You may also consider trying some of the more exotic potato varieties, such as those with blue or purple flesh.

While the chlorophyll that turns skins green is harmless, sun exposure can produce large amounts of a toxic chemical called solanine. This is because they contain an enzyme called polyphenol oxidase, which reacts with oxygen and turns the flesh a grey or brownish color.In fact, one study found that storing potatoes in cool temperatures more than quadrupled their shelf life, compared to storing them at room temperature ( 3). Smooth skin: Potatoes that have been damaged by cold temperatures may develop pitted skin and brown centers, so look for smooth textures. Very low temperatures can cause “cold-induced sweetening.” This happens when some of the starch is converted to reducing sugars ( 10).

I have often used deep holes dug in the garden for temporary potato storage, but it is not a long-term solution because the potatoes tend to develop skin issues that are rare when potatoes are kept in dry storage. I tried storing potatoes in a buried garbage can, which should have worked but did not. The potatoes inside stayed too damp and went gooey, which could have been due to many factors, including my own mistakes. Specialized Refrigeration Cooking and cooling also increase the formation of resistant starch, a type of carbohydrate that humans cannot digest and absorb. However, leftovers may become watery or gummy, since potato starches change shape and release water as they cool ( 22).A fresh potato smells like the ground it’s grown in, but a potato that’s gone bad will smell mouldy and musty. How to use leftover potatoes Solanine is also toxic to humans when consumed in very high quantities and can cause nausea, vomiting and diarrhea. A few cases of death have even been reported ( 7).
