Vegetable Sprouts And Safety
Many vegetables can sprout. Some sprouting vegetables can not be consumed anymore while others might be more nutritious. It is known that the sprouted potatoes cannot be eaten because the potato will contain the anemone which is used to protect itself against pests. The content of anemone in normal mature potato is extremely low which is considered as harmless to human body. However, when the potato once began to sprout and turn green, they will produce a large amount of anemone which is 50 times of the normal potatoes. Potatoes will be toxic and can not be eaten anymore. This is because anemone has a strong corrosive effect on the gastrointestinal tract, as well as central paralysis and haemolysis. If taken, the symptom will be dry mouth, nausea, vomiting, abdominal pain, diarrhea and other acute gastritis symptoms. People can even get fever, breathing difficulties and convulsions.
Sweet potato sprouts don’t produce any harmful substances. However, germinated sweet potatoes tend to have moldy issues. If its skin is turning brown or black, it is usually caused by a type of black spot bacteria. Some other bacteria may produce toxins such as sweet potato ketone which is possible risky to human health. Even after boiled and grilled, its biological activity will still not be destroyed completely. Generally, the sprouting will have no safety issues because they don’t produce toxins. They’re just a little less nutritious and you should not worry too much about that.
On the contrary, some vegetables like yellow beans, peas and garlic often stored more nutrients such as protein, carbohydrate, sprouts are in the sprouting process. In general, vegetable seeds will become more nutritious after the spouting.
