The epidemic has been repeated
Many people have developed the habit of hoarding vegetables
But there are no vegetables that are consumed in time
Especially rhizomes
Always easy to germinate
But germination cannot be avoided
What foods cannot be eaten after sprouting?
And what foods double their nutrients after germination?
Foods that can no longer be eaten after germination
The killer in potato sprouting is a substance called dragon anthrophyll, which is a toxic alkaloid, which is eaten by people with mild nausea, vomiting, diarrhea, and severe heart failure and paralysis of the respiratory center, resulting in death.
In fact, normal potatoes also contain agaricin, but the content is very low and will not cause harm to the human body.
And when potatoes begin to sprout and turn green, potatoes will produce a large amount of longalin, which is 50 times that of normal potatoes, which is "highly toxic" to the human body. If you eat 200 mg of longanthrin at a time, about 30 grams of potatoes that have turned green and sprouted, symptoms of poisoning can occur in 15 minutes to 3 hours.
Can sprouted potatoes be eaten?
First of all, sprouted potatoes are not recommended to eat. I really don't want to waste, for a small amount of potatoes that sprout, there are still ways to sprout a sign.
ps: It is recommended to cut into silk when soaking, which is conducive to the dissolution of dragon sunflower in water!
However, if the area of potato greening is large and there are many parts of germination, it should be resolutely thrown away and not eaten again. If you can't judge whether the germination is more or less, or throw it away and don't eat safely.
Precautions
Store potatoes in a dry, cool place, or potatoes and apples together and store them tightly sealed, as the ethylene gas released by apples effectively inhibits germination.
Which sprouted foods have reduced nutritional value?
ginger
Although ginger sprouts are not poisonous, nutrition is greatly reduced. This is because with the storage of time, the buds absorb the nutrients of ginger, the ginger meat becomes very dry, it is dry and shriveled to eat, the nutrition will "shrink", and the taste will also become worse. So if you find that ginger has buds, you must use it as soon as possible.
Pay special attention
If ginger has rotted and grown mold, the rotten part and surroundings are not suitable for consumption, because ginger can produce safrin in rotten mold, which may make liver cells degenerate, necrosis, and even induce liver cancer.
Recommended storage method
Use a flower pot that you don't use at home, fill it with some sand, put the ginger in and cover it with sand, and keep the sand moist for a long time.
taro
Taro is actually a relatively durable food, but spring can not escape germination.
Like ginger, taro buds are not harmful to health, but their taste and nutritional value are reduced. Because of the consumption of nutrients and the loss of water due to germination, it will taste worse than if it did not sprout.
Pay special attention
Taro is not tolerant to low temperatures, so do not put fresh taro in the refrigerator. When the temperature is lower than 7 ° C, it should be stored in a warmer place indoors to prevent rot due to frostbite.
Recommended storage method
Hang it, buy a mesh bag, and put the taro in a dry, cool and ventilated place.
Red (purple) potato
Sweet potatoes and potatoes belong to the potato category, but after germination, they are still different from potatoes. After it germinates, it does not produce harmful ingredients to the human body and is edible. However, the same nutritional value as ginger and taro will be lost.
Pay special attention
Sprouted sweet potatoes are prone to mildew. If the epidermis has brown or black spots, which are contaminated by black spot bacteria, the toxins such as sweet potato ketone produced by it, even after boiling and roasting, biological activity will not be destroyed, and sweet potatoes in this condition should not be eaten.
Therefore, sprouted sweet potatoes can be eaten, and moldy sweet potatoes cannot be eaten.
Recommended storage method
The sweet potatoes are placed in a cardboard box, and the sweet potatoes can be separated from the sweet potatoes with dry paper, which is conducive to moisture protection and reduces the possibility of germination.
onions
Harvested onions are dried and stored for a long time without germination or mildew. But in the spring around 15 ° C, onions are most likely to germinate. Onions that have sprouted or even grown seedlings do not produce substances harmful to the human body and can still be eaten.
However, in the same way, germinated nutrients are transferred to the top for bud growth, resulting in a decrease in nutrient content. At the same time, the taste will be more spicy.
Recommended storage method
Suspension preservation method, you can use the clean mesh bag at home, put the onions one by one, tie a knot for each one, and then hang the whole string in a ventilated and cool place, and then use scissors to cut one down from the tail end when you want to use it.
Foods that double their nutritional value after germination
Soybeans, mung beans, peas
The nutritional value of the beans themselves is very high, and after germination, it actually becomes another ingredient - soybean sprouts, mung bean sprouts, pea sprouts, which increases nutrition.
For example, after soybeans sprout, their fat and sugar content decreases, while beneficial nutrients such as protein, isoflavones and vitamin C increase accordingly.
Soybean sprouts and mung bean sprouts are more suitable for people with poor digestive function. Compared with soybeans and mung beans, pea seedlings are very recommended, and their carotene content can reach 2700 μg / 100 g, while the carotene content of melons and fruits and vegetables that people often eat is below 100 μg / 100 g, a difference of 27 times.
peanut
If it is deliberately cultivated and germinated, the vitamin C content of peanuts will be greatly increased after germination, and it will also increase resveratrol, flavonoids, which have antioxidant effects on the human body.
However, in general, their own peanuts have sprouted, and many of them may be caused by damage to the outer skin of peanuts. Peanuts are prone to mildew, forming toxic aflatoxin, which is a strong carcinogen and is recommended not to be consumed again.
garlic
Sprouted garlic has a higher antioxidant content than fresh garlic, and its nutritional content in terms of dietary fiber, vitamin C, vitamin A, carotene, etc., is also better than that of unsprung garlic.
However, it is important to remember that discolored, moldy garlic can no longer be eaten.
