In addition to sprouting, physical damage, greening, and a bitter taste are three signs that a potato’s glycoalkaloid
Glycoalkaloids are a family of chemical compounds derived from alkaloids to which sugar groups are appended. Several are potentially toxic, most notably the poisons commonly found in the plant species Solanum dulcamara (bittersweet nightshade) and other plants in the genus Solanum, including potato.
Raw potatoes should be firm to the touch with tight skin that’s free of large bruises, black spots, or other blemishes. If a potato has become soft or mushy, you should throw it out. Though it’s normal for potatoes to smell earthy or nutty, a musty or moldy odor is a hallmark of spoilage.
Bad potatoes contain high levels of solanine and can cause solanine poisoning. Symptoms include nausea, diarrhea, stomach cramps, vomiting, headache, dizziness, among other things. Mild solanine poisoning should only last around 24 hours- but definitely seek medical help if you need it!
Sprouted potatoes that are still firm, have relatively small sprouts, and don’t show any wrinkles or shriveling are okay to eat, as long as you cut off the sprouted parts and soft spots. However, there’s still a chance you could get sick.
So, can you eat soft potatoes? Yes, you can. If they aren’t overly soft and shriveled, don’t have too much green coloring, and aren’t moldy then soft potatoes are safe to eat. If eyes or any small impurities start to show, they can easily be removed with a small paring knife or peeler for safe cooking.
But what if they’re just a little soft, or have a few sprouts? As long as the potatoes are still mostly firm, they’re fine to cook. Potatoes are 80 percent water, so softness is usually just a sign of dehydration. But if they’re extremely mushy or shriveled, do not pass go.
Rotting potatoes give off a noxious solanine gas that can make a person unconscious if they’ve inhaled enough. There have even been cases of people dying in their root cellars due to unbeknownst rotting potatoes.
So, if you keep your potatoes somewhere that it’s cool, dark, and they have access to moisture, they will joyously begin to spread their sprouts and grow in the shadows. The more sprouts that grow, the more depleted their nutritional value becomes.
Potatoes can last for up to several months in a cool pantry. If stored at room temperature, they are best if eaten within one to two weeks. Once cooked, keep them in the fridge for no more than three days.
Uncooked potatoes are best kept somewhere cool and dry, but don’t keep them in the fridge. Putting potatoes in the fridge can increase the amount of sugar they contain, and lead to higher levels of a chemical called acrylamide when the potatoes are baked, fried or roasted at high temperatures.
Do you need to remove the eyes? While most of the time the removal of the potato eyes is purely cosmetic, you should definitely remove the eyes if your potato has started to sprout in your pantry. Potatoes are a perennial from the nightshade family of plants, Solanaceae.
The ethylene gas given off by an apple will prevent potatoes from sprouting, while keeping onions nearby will actually cause them to sprout. In addition, moisture and exposure to light cause potatoes to spoil and turn green, so to keep potatoes fresh for up to 2 weeks, loosely store them in a paper bag.
Lenticels swell when tubers are exposed to highly moist soil or standing water for several days. When the bacteria enter the tuber, the cut, abrasion, or lenticel begins to discolor, decay, and even liquefy. The discoloration is creamy to tan and often outlined by a brown to black margin (Figure 2).
Solanum tuberosum poisoning. Potato plant poisoning occurs when someone eats the green tubers or new sprouts of the potato plant. This article is for information only. DO NOT use it to treat or manage an actual poison exposure.
Avoid closed containers, like resealable plastic bags or airtight storage containers—they’ll trap moisture and will cause the potatoes to mold and spoil faster. The best place to store potatoes is in a paper bag or in an open bowl or basket. Just make sure they aren’t too crowded—potatoes need air!
As all of us have seen, potatoes that are left for too long will inevitably begin to sprout. The sprouts grow from what we call the “eyes” of the potato. Before the sprouts begin to grow, the eyes can be identified as slight indents in the skin where there is a dry nub sticking straight out from the potato.
Is it ok to eat potatoes that have sprouted? A: The sprouts taste bitter, just knock them off if they are small and bake or use as usual. Sometimes the emerging sprouts are referred to as “peepers” coming out.
If you know how to store them properly, they’ll stay fresh weeks, or possibly even months, longer. All you need to store them so they’ll stay fresh longer is a cardboard box, a paper or mesh bag, or a basket. Your potatoes will last four to six months when properly stored.
Store whole eggs in a cool dry place, ideally in the fridge, until you use them. Storing eggs at a constant cool temperature will help to keep them safe. Do not use eggs after their ‘best before’ date.
You want to be able to eat your potato without worrying if you are going to get food poisoning or botulism. Here’s how you can ensure that your baked potatoes are safe to eat. DON’T let your potato sit out in the open at room temperature for over four hours regardless of whether or not it is wrapped in aluminum foil.
Abstract. Solanine is a toxic glycoalkaloid known to accumulate under certain conditions in potato plant, sprouts and tuber in levels which, if ingested, may cause poisoning in humans and farm animals.
