Is it possible to eat potatoes if it has sprouted
With the advent of spring, most of the mid-season potatoes, stored even under almost ideal conditions, begin to sprout. If the crop is kept in a closet or on a city balcony, the characteristic white shoots on the surface of the tubers begin to hatch already at the end of winter.
Chemical composition and calorie content
Potato is perhaps the most popular vegetable on our tables. And this is not surprising, because it is rich in vitamins, minerals, and due to calorie content it well nourishes and restores the body.
On average, a vegetable contains such substances (100 g):
- proteins - 1.9 g;
- fats - 0.38 g;
- carbohydrates - 17 g;
- fiber - 1.38 g;
- water - 79 g.
Calorie content of potato - 76.8 kcal. In addition, potatoes are rich in vitamins A, groups B, C, D, E, H, K, PP, minerals (Ca, Si, Mg, Na, Ph, Cl, Fe, I, Co, Mn, Cu, Mo, Se, F, Cr, Zn, etc.). All of these substances, and some others, are found in fresh potatoes.
Did you know? In its structure, solanine is close to the animal hormone cortisone and cardiac glycosides. Synthetic cortisone became available only after the hormone was synthesized from solasodine, the closest relative of solanine.
Why sprouted potatoes are considered harmful
The reason sprouted potatoes can be harmful to our bodies is because of the high solanine content in these tubers. Solanine is an organic toxic glycoside found in many plants of the nightshade family (tomatoes, nightshade, eggplant, potatoes, peppers, etc.) and not only. The substance consists of a glucose molecule and an alkaloid of solanoidin.
It functions as a fungicide and insecticide, protecting the plant from pests and diseases. Closer to spring, the tubers begin to prepare for planting - protection against potential fungal diseases and parasites is included. This happens approximately like this: the sugar contained in the vegetable and part of the starch under the influence of dampness, oxygen and time are combined with solanoidin. As a result, solanine is formed. The alkaloid is present in all parts of the bush.
Potatoes that can be stored until next summer will already contain almost 3 times more solanine - about 0.11%. After another year of storage in the substance that was potatoes, the alkaloid content will increase to 1.3%. The highest concentration of toxic substance is found in young sprouts up to 1 cm long - about 5%. In sick wrinkled tubers, toxin is 100–200% more than in normal healthy potatoes up to six months old.
Important! Solanine has the ability to accumulate in the body, you should not forget about it if you often consume solanaceae a lot. In addition, the poison is not afraid of high temperatures, but is partially washed with water. That is why the sprouted potatoes need to be cooked, not fried or baked.
Why can not eat sprouted potatoes
Talking about the danger in relation to potatoes, even if hypothetical, follows from the middle of winter. By the beginning of the new year, tubers lose most of their nutrients (vitamins), while the content of solanine increases. The poison in the tubers is unevenly distributed - its maximum content falls on the area located directly below the surface of the tuber (subcornal zone), in the area around the eyes, in green spots and sprouts.

So even sprouted spring potatoes are almost no danger. To seriously talk about it, you need to eat a few kilograms of sprouted unpeeled vegetable in its raw form. From the foregoing, we can conclude that, in principle, sprouted potatoes can be eaten. Such food is unlikely to cause significant harm to you, however, you should hardly expect any benefit from it.
How to cook sprouted potatoes
Do not rush to get rid of sprouted potatoes - it can be used, and not only for food, although this way too. For example, it is an excellent raw material for cooking homemade mash, and later moonshine. In addition, in many families in Russia, Ukraine, and Belarus, it is not accepted to throw away products that are not quite salable.
Did you know? In early spring, very small smooth potatoes appeared on the markets, supposedly local young. It is highly likely that these are tubers grown in the cellar on old potatoes, and they are really extremely dangerous - the solanine in them is an order of magnitude higher than in old sprouted tubers.
In a fresh tuber, from which the top layer has been removed (peel with a thin layer of pulp beneath it), only 5–10% of the alkaloid from the initial content remains. That is, 90% of the toxins are found in and under the peel . The same applies to sprouted potatoes, only with the amendment that in such tubers the highest concentration falls on the sprouts, areas around the eyes and all green areas, therefore, it is necessary to remove first of all all of the above parts.
The main thing to remember: only boiled tubers are absolutely harmless to health, as an option, stewing is allowed. For all other cooking methods (frying, baking, especially in uniform), forget it. Cut the peel by grabbing a sufficient layer of pulp. After that, use the product as you see fit: add to the soup, cook mashed potatoes, make the filling for dumplings or pies, casserole in the oven.
On our tables, the most popular among these products are the following:
- cabbage;
- beet;
- any greens;
- garlic;
- sour cream.
Important! Do not feed dishes containing sprouted potatoes to a child under the age of three.
Features of the use of sprouted potatoes in the diet of pets
Dogs and cats can be introduced into the diet such a product in boiled form in small quantities and not more than 1 time per week. It is mixed into porridge or other food in small volumes. Caution should be taken when feeding rabbits.
It should be borne in mind that for these animals, the lethal dose of solanine is 0.6–1.2 mg / 1 kg of animal weight. For feeding a decorative animal living in an apartment, such a product should not be used at all. For rabbits that are raised for slaughter, the proportion of such feed should not exceed 40% of the diet.
