Can you still eat the sprouted sweet potato when it is sprouted

Can you still eat the sprouted sweet potato if you eat it we all have experience. If the sweet potatoes are not stored properly, they will sprout. Can the sprouted sweet potatoes be eaten, and will they produce as much poison as the sprouted potatoes? Let's solve the mystery.

I. sweet potatoes can be eaten after germination

After germination, sweet potatoes will not produce harmful ingredients like potatoes. As long as the buds on sweet potatoes are removed, they can be eaten, not to mention the legendary poisoning symptoms. But one thing we should pay attention to is that, because of the loss of nutrition and water, the sweet potato will not only taste bad, but also lose its edible value. As for the saying that eating sprouted sweet potatoes can cause poisoning, there is no basis, nor is it scientific. It is a mistake in life. Nutritionists believe that sweet potato is not only a nutritious food, but also a therapeutic effect on many diseases. There are many advantages of eating sweet potato, but we must pay attention to scientific methods.

Although sweet potato sprouts can eat, but if the skin is brown or black spots can not eat, it is due to the black spot bacteria pollution. The toxin discharged by the black spot pathogen contains the sweet potato ketone and sweet potato ketone alcohol, which makes the sweet potato hard and bitter and highly toxic to the human liver. The biological activity of the toxin will not be destroyed. After eating, the disease usually occurs within 24 hours, with nausea, vomiting, diarrhea and other gastrointestinal symptoms. Serious, still send high fever, have a headache, wheeze, benefit Zhi not clear, vomit blood, coma, even die.

2. Why sweet potatoes are sweet when they are put on for a long time

The sweet potato has been put for a long time, the moisture is reduced a lot, and the skin is wrinkled. The decrease of water content has a great influence on the increase of sweetness. There are two reasons: the first is the decrease of water evaporation and the relative increase of sugar concentration in sweet potato. Second, during the process of storage, water participated in the hydrolysis reaction of starch in sweet potato, and starch hydrolyzed into sugar, which increased the sugar content in sweet potato. Therefore, we feel that the sweet potato which has been stored for a long time is sweeter than the newly excavated sweet potato.
