Sweet potato is a kind of rural people's multigrains, can be processed into starch, made into vermicelli and various vermicelli, dried into potato chips, but also the rural people raise pigs of high-quality feed, sweet potato use is very much, is deeply loved by people plant food.
Rural sweet potatoes are usually stored in cellars after harvesting. During the storage process, because the temperature and humidity of the cellar are very suitable, the dormancy period of the sweet potato is broken, so that the sweet potato germinates a lot of young shoots. There is a fundamental difference between sweet potato sprouting and potato sprouting.
According to the data, the potatoes planted by farmers are very easy to germinate. Potato germination, in the potato sprout site and the root part of the young sprout, under the action of the biological enzyme active substance at the time of potato germination, produces a substance called longalin, also known as longki alkali, which is very toxic to people.
If people eat potatoes that have sprouted, longanin will produce a very strong poison to people, the light will appear poisonous phenomenon, and the heavy will be life-threatening. Therefore, sprouted potatoes can either be eaten after special treatment, or simply cannot be eaten.
According to the data, when the sweet potato sprouts, the active biological enzymes in the sweet potato tubers are unlikely to produce chemicals harmful to the human body such as longanin in the active process. Therefore, after the sweet potato sprouts, if it is eaten, there is no harm to the human body. Therefore, sweet potatoes have sprouted, unlike potatoes, they are safe to eat.
However, in the storage process of sweet potato tubers, due to the influence of suitable storage environment, sweet potato tubers are still in a very strong biological activity, and they begin to consume nutrients on the inside of sweet potato tubers and germinate new shoots.
Because, in the storage process, sweet potato is an independent tuber individual, without whiskers and leaves, it is impossible to obtain nutrients from the outside world, providing sufficient nutrition for tuber germination, and can only meet the nutrients needed for tuber germination by consuming the nutrients stored in the sweet potato tubers.
And because the nutrients in the sweet potato tubers are very limited, once the sweet potato tubers germinate young buds, they need to absorb and consume the nutrients in the tubers, so that the nutrients in the sweet potato tubers are gradually reduced.
Therefore, after the sweet potato tubers germinate, the nutrients on the inside of the sweet potato tubers will be lost in large quantities and consumed by the young shoots, reducing the nutrient content in the sweet potato tubers.
The nutrients in the sweet potato are mainly starch, fructose, vitamins and active enzymes, which are transferred to the germinating shoots. In this way, if the sweet potato is eaten, it is much less nutritious than when it is not sprouted, and the taste of eating decreases, the obvious difference is that the sweetness of the sweet potato has decreased, the hemicellulose on the inside has gradually thickened and increased, and the waxiness of the sweet potato meat has decreased and become rough.
However, when sweet potatoes have just sprouted young, the nutrients consumed are very small, so the decline in the eating experience of sweet potatoes is not obvious. The longer the sweet potato sprouts, the bigger and more, the longer the time, the more nutrients are consumed, the more the quality of the sweet potatoes declines, and the worse the taste.
